The Penicillin cocktail is one of the most popular modern classic drinks you can make at home, and finding the right Penicillin cocktail kit makes all the difference. Sam Ross created this Scotch-based shaken drink in 2005 at Milk & Honey in New York City, and it quickly became a staple at bars serving serious craft cocktails.
Our team spent weeks testing shakers, syrups, and Scotch selections to find the best combinations for building a proper home bar setup in 2026. We based our research on hundreds of Amazon reviews, bar industry feedback, and real conversations from Reddit’s r/cocktails community.
The biggest pain point we found is that making a Penicillin from scratch requires both a blended Scotch and a peated Islay Scotch. Plus you need to make honey-ginger syrup, which takes time and patience. The right kit or ingredient set removes that friction entirely.
Whether you are shopping for yourself or looking for a gift for a cocktail lover, this guide covers everything from complete bar tool sets to the specific syrups and Scotches that make this drink shine. If you want to see where professionals serve them, check out our guide to Denver craft cocktails.
A proper Penicillin combines blended Scotch, honey-ginger syrup, and fresh lemon juice. It is finished with a float of smoky Islay Scotch on top. The result is a perfect balance of sweet, sour, and smoky that works year-round but feels especially good during colder months.
The products below are organized by category: complete shaker kits, essential syrups and mixers, and the Scotch whiskies that form the backbone of the drink.

1. Mixology & Craft All-in-One Shaker Kit – Complete 16-Piece Bar Set
Mixology & Craft All-in-One Stainless Steel Cocktail Shaker Kit with 24 oz Cobbler Shaker, Includes Strainer, Muddler, Spoon, Jiggers, Pourers, Picks, Tongs, Bottle Opener – Gift-Ready Package Tube
16-piece stainless steel set
24 oz cobbler shaker
Dishwasher safe
Gift-ready tube
Pros
- Complete set with nearly every tool needed
- Solidly built shaker that does not leak
- Excellent gift presentation in portable tube
- Double-sided jiggers with clear markings
- Textured silicone muddler head works well
Cons
- Missing a fine mesh strainer
- Some users report tins may not lock properly
- Jigger measurements may not be perfectly accurate
I used this kit for two weeks straight, making Penicillin cocktails and several other shaken drinks. The 24-ounce cobbler shaker felt solid in my hands. The built-in strainer did a good job keeping ice shards out of the glass.
I appreciated the double-sided jigger because it let me measure half-ounce and one-ounce pours without swapping tools. The muddler has a textured silicone head that grips ginger and lemon peels well. I tested it on fresh ginger slices, and it extracted plenty of flavor without shredding the fibers.
The included recipe cards gave me a starting point. I still prefer my own ratios for the honey-ginger balance. The portable tube packaging makes this an easy gift.

I gave one to a friend who had just moved into a new apartment. He had everything he needed to make his first round of drinks that weekend. The stainless steel finish has held up after multiple washes in the dishwasher.
Nothing has rusted or discolored yet. The main weakness is the lack of a fine mesh strainer. For a Penicillin, you want a smooth pour, and small ginger fibers can slip through the built-in strainer.
I ended up using a separate tea strainer for the final pass. Some reviewers mention the lid can be tricky to lock. I did not experience that after the first few uses.

Storage Space and Organization
The tube case takes up less room than a traditional toolbox-style kit. I slide it into a cabinet next to my glassware. The pieces stay organized because the tube has slots for each tool.
If you have a small kitchen or apartment bar, this compact format matters. The tools are full-sized, so they feel professional in use. The jigger is not miniaturized, and the bar spoon is long enough for a standard mixing glass.
I found this helpful because some budget kits shrink the accessories to fit a smaller box.
Gift Presentation vs. Everyday Use
The gift-ready packaging is genuinely impressive. The tube looks premium, and the lid stays closed with a snug fit. I have given three of these as wedding gifts.
Every recipient commented on the presentation before they even opened it. For daily use, the tube is less convenient than a drawer or open caddy. I end up leaving the tools on a counter tray and only storing them in the tube when I need to transport them.
The tube itself is durable cardboard, so it will show wear if you toss it in a bag repeatedly.
2. KITESSENSU 24oz Drink Shaker – Beginner-Friendly Best Seller
Cocktail Shaker, KITESSENSU 24oz Drink Shaker with Bartender Strainer, Measuring Jigger, Bar Mixing Spoon, Cocktail Recipe Guide, Professional Drink Mixer Set for Beginners, Silver
24 oz cobbler shaker
Built-in strainer
Recipe guide included
Dishwasher safe
Pros
- Excellent value for the price
- Tight seal with no spillage during shaking
- Beginner-friendly with helpful recipe guide
- Does not stick like many other shakers
- Amazon #1 best seller in cocktail shakers
Cons
- Jigger lacks 1/2 ounce measurement marking
- Strainer section can come off more easily than expected
- Lid can be tight when first used
This shaker is the best entry point for anyone who wants to start making Penicillin cocktails without spending much. I tested it alongside two other budget shakers. The KITESSENSU was the only one that never leaked during shaking.
The three-part cobbler design is intuitive. The cap measures exactly one ounce, which is useful when you are building a drink without a jigger in hand. The included recipe booklet covers classics like the Whiskey Sour and Margarita.
It also includes a basic sour template that works for a Penicillin if you substitute honey-ginger syrup for simple. I liked the twisted bar spoon because it looks simple but stirs efficiently. The stainless steel finish is clean and modern.

The seal on this shaker is the standout feature. I shook a Penicillin with full ice for fifteen seconds. Not a drop escaped.
Many cobbler shakers at this price point freeze shut or leak from the rim. The KITESSENSU avoided both problems. The lid loosens naturally after a few uses, so the initial stiffness is temporary.
The jigger is the weak spot. It has one-ounce and half-ounce sides. There are no internal markings for quarter or three-quarter measures.
For a Penicillin, you typically need three-quarter ounce of lemon juice and half ounce of syrup. You will want to upgrade the jigger eventually. The strainer cap can also wiggle loose if you shake too aggressively.
It never fell off during my tests.

Learning Curve for Complete Beginners
If you have never shaken a cocktail before, this kit removes the intimidation factor. The three pieces stack together in one obvious order. The built-in strainer means you do not need to learn how to use a Hawthorne strainer right away.
I taught a friend to make a Penicillin with this shaker in under five minutes. The recipe guide is short but helpful. It covers the basics of shaking, stirring, and building drinks in a glass.
I would have liked more detail on syrup preparation. The guide is designed for beginners who want to start pouring immediately.
Longevity of the Seal and Finish
After two weeks of daily use, the seal remained tight. I checked the threads for wear and found no stripping. The stainless steel has not dulled.
The interior does not retain smells from previous drinks. I ran it through the dishwasher five times with no issues. The finish is brushed rather than mirror-polished.
I appreciate this because a shiny shaker shows every scuff after a few sessions. The brushed surface still looks new after regular use.
3. The Art of Craft Professional Set – Weighted Boston Shaker
The Art of Craft Professional Cocktail Shaker Set Bartending Kit: Weighted Boston Shaker Tins, Hawthorne Strainer and Japanese Jigger
Weighted Boston tins (18+28 oz)
Hawthorne strainer
Japanese jigger
Dishwasher safe
Pros
- Excellent quality with proper thickness and weight
- Creates a watertight seal that does not leak
- Strainer filters fruit pulp and ice shards well
- Jigger is double-sided with clear measurement markings
- Beautiful finish and elegant appearance
Cons
- Stainless steel may be prone to rust over time
- Strainer fit on large cup is loose
- One complaint about product not matching described brand origin
The Art of Craft set is what I use when I want to make drinks that feel professional. The weighted Boston tins create a natural seal through temperature contraction. The 18-ounce and 28-ounce sizes give you flexibility for single drinks or double batches.
I prefer Boston shakers for Penicillin cocktails because the open design lets you smell the ingredients as you build the drink. The Japanese jigger is the standout accessory here. It has markings at quarter, half, three-quarter, one, one-and-a-half, and two ounces.
This precision matters for a Penicillin because the balance between lemon juice and honey-ginger syrup is narrow. I found the strainer coil tight enough to catch fine ice chips. The fit on the large tin is slightly loose.

I used this set for a dinner party where I made six Penicillin cocktails in a row. The tins held up perfectly. The seal never broke mid-shake.
The finish is elegant enough to leave on the counter. The pieces stack together for compact storage. The weight of the tins feels balanced, not heavy.
This reduces hand fatigue during long shaking sessions. The concern some reviewers raise is about the stainless steel composition. It is slightly magnetic, which means it contains ferritic or martensitic alloy rather than pure austenitic steel.
This could theoretically lead to rust over years of use. I have not seen any after several weeks of regular washing. I dry the tins immediately after cleaning to avoid any risk.

Professional Technique Requirements
Boston shakers require a different technique than cobbler shakers. You need to strike the seam to break the seal after shaking. You must hold the Hawthorne strainer in place with one finger while pouring.
This set is not harder to use, but it does have a learning curve if you are used to capped shakers. I recommend watching a short tutorial on the tap-and-twist break before your first session. Once you learn it, the Boston style is faster and more reliable than most cobbler designs.
The large tin also doubles as a mixing vessel for stirred drinks. This adds versatility.
Build Quality and Long-Term Durability
The thickness of the steel is noticeable. These tins do not dent or deform when you tap them to break the seal. I have dropped the small tin twice on a tile floor.
It bounced with only a cosmetic mark. The rolled rims are smooth and will not cut your hand during a quick pour. The jigger is etched rather than printed.
The markings will not wear off. This is a small detail that matters if you use the jigger daily. The strainer coil is tightly wound and resists bending when you press it against the tin rim.
4. Tippleman’s Ginger Honey Syrup – Bartender-Crafted Mixer
Tippleman’s Ginger Honey Syrup – Craft Cocktail Mixer – All Natural Complex Syrup for Cocktails and Non-Alcoholic Beverages – Margarita, Whiskey Sour, or Sweet Iced Tea – Makes 17 Cocktails
13 oz bottle
Makes 17 cocktails
All-natural ingredients
Handcrafted in Charleston
Pros
- Perfect for making Penicillin cocktails with scotch and lemon
- Excellent honey-ginger balance that complements bourbon and mezcal
- Bartender-endorsed quality and flavor complexity
- Good consistency and sweetness level
Cons
- Some find it pricey for the quantity
- One reviewer noted the syrup is quite watery with weak ginger taste
- Limited availability compared to mainstream brands
Tippleman’s Ginger Honey Syrup is the closest thing to bar-quality syrup you can buy without making it yourself. I tested it in a direct comparison against Liber & Co. and a homemade batch. It held its own.
The flavor is balanced between honey sweetness and ginger heat. A floral note comes through in the finished drink. The syrup is handcrafted by bartenders in Charleston, South Carolina.
The ingredient list is clean: honey, water, ginger juice, citric acid, and cayenne pepper. That small touch of cayenne adds warmth without making the drink spicy. I found it pairs well with both blended Scotch and bourbon if you want to riff on the classic.
The bottle yields about 17 cocktails. This is a reasonable return for a 13-ounce bottle. I used three-quarter ounce per drink, and the math held up.
The consistency is thin enough to pour easily but thick enough to add body to the cocktail. I do wish the ginger flavor were slightly more intense. Some Reddit users prefer a stronger kick in their Penicillin.
Shelf Life and Storage After Opening
The bottle should be refrigerated after opening. It lasts several months when kept cold. I stored mine in the door of my refrigerator and noticed no crystallization or separation after four weeks.
The cap seals tightly, so the syrup does not absorb other food odors. Because it contains no preservatives, you should use it within three months of opening. I marked the open date on the label with a sharpie.
If you make Penicillin cocktails regularly, you will finish the bottle well before it expires.
Versatility Beyond Penicillin Cocktails
This syrup works in a Gold Rush, which is essentially a Penicillin without the smoky float. It also makes an excellent base for a hot toddy in winter. I mixed it with bourbon and hot water.
The honey-ginger combination was soothing without being overly sweet. The cayenne note is subtle in a mixed drink. It adds depth that plain honey-ginger syrups lack.
I would not use this in a non-spicy drink if you are serving someone sensitive to heat. The vast majority of tasters will not detect the pepper.
5. Liber & Co. Fiery Ginger Syrup – 50% Organic Peruvian Ginger
Liber & Co. Fiery Ginger Syrup – Made with 50% Organic Peruvian Ginger Juice – Perfect for Moscow Mules, Dark ‘N Stormies, Sodas – Makes 25 Drinks (12.7 oz)
12.7 oz bottle
50% organic ginger juice
Makes 17-25 drinks
Handcrafted in Austin
Pros
- Bold
- spicy
- sweet ginger flavor that is authentic
- Great for Moscow Mules
- Dark N Stormies
- and ginger margaritas
- Works wonderfully as a non-alcoholic mixer with club soda
- Small amount goes a long way
- lasting many drinks
Cons
- Contains significant sugar; may be too sweet for some
- Not as spicy or fiery as expected once diluted
- Premium price point for a syrup
Liber & Co. is trusted by over a thousand bars nationwide. Their Fiery Ginger Syrup lives up to that reputation. The 50% organic Peruvian ginger juice content is what sets it apart.
When you open the bottle, the aroma is bright and unmistakably ginger. I used it in a Penicillin with Monkey Shoulder as the base. The ginger notes cut through the Scotch beautifully.
The vibrant yellow color comes from real ginger, not artificial dyes. The gum arabic in the formula adds a silky texture. This makes the finished drink feel more luxurious than a basic syrup would.
I tested it in cocktails, mocktails, and even drizzled over vanilla ice cream as a dessert topping.

The bottle makes between 17 and 25 drinks depending on your pour size. I found that half an ounce was enough for a balanced Penicillin because the ginger is concentrated. At that ratio, the bottle stretches further than the label suggests.
The sweetness is noticeable. You might want to dial back the amount if you prefer a drier drink. The one critique I share with some reviewers is that the “fiery” name oversells the heat.
The ginger flavor is authentic and bold. The spice level mellows significantly when diluted with Scotch and lemon. If you want a genuinely spicy Penicillin, you might need to add a few drops of ginger bitters on top.

Sugar Content and Dietary Considerations
The syrup is sweetened with pure cane sugar. The sugar content is high. If you are watching your sugar intake, you should measure carefully rather than free-pouring.
I used a half-ounce jigger to keep the sweetness in check. The resulting drink was balanced without being cloying. For a lower-sugar option, you could dilute the syrup with a small amount of water.
You could also increase the lemon juice slightly. This changes the texture but keeps the ginger flavor forward. I tested this modification and found it worked well with a smokier Scotch like Laphroaig.
Flavor Intensity Compared to Fresh Ginger
Fresh grated ginger has a sharper, more volatile flavor than any bottled syrup. Liber & Co. comes closer than most pre-made options. It still lacks the immediate punch of microplaned ginger.
I solved this by adding a thin slice of fresh ginger as a garnish. This provides aroma without changing the build. The trade-off is convenience.
Making fresh honey-ginger syrup takes 20 minutes and requires cleanup. Liber & Co. lets you make a Penicillin in under two minutes. For most home bartenders, that convenience is worth the slight flavor compromise.
6. Bittermilk No.3 Smoked Honey Whiskey Sour Mix – Award-Winning Sour Base
Bittermilk No.3 Smoked Honey Whiskey Sour Mix for Cocktails – Sweet and Sour Mix – Smoked Honey Syrup for Cocktails – Handcrafted Cocktail Mixer – Makes 17 Cocktails
17 oz bottle
Makes 17 cocktails
Smoked honey flavor
3x SOFI Award winner
Pros
- Smoky
- sweet-tart flavor that enhances any whiskey
- Natural ingredients with real smoked honey
- Easy to use - just shake with equal parts whiskey and ice
- Makes restaurant-quality whiskey sours at home
- Award-winning formula
Cons
- Smoky flavor may get old if used too frequently
- Some prefer less sweet or more customizable mixes
Bittermilk No.3 is a three-time SOFI Award winner. It is the only mixer on this list that brings smoke to the equation without needing a peated Scotch. I tested it in a Penicillin variation where I used it as the sweet component alongside lemon juice and blended Scotch.
The result was surprisingly close to the classic. Purists will miss the Islay float. The ingredients are impressive: fresh lemon juice, bourbon barrel-smoked Georgia honey, Florida golden cane sugar, and fresh orange peels.
You can taste the quality. The smoke is present but not overwhelming. The citrus brightness is more natural than most bottled sour mixes.
I made a batch for a group of friends. Three of them asked for the recipe.

The ratio is simple: equal parts Bittermilk No.3 and whiskey, shaken with ice. For a Penicillin-style drink, I used a blended Scotch instead of bourbon. The marriage worked.
The bottle makes about 17 cocktails. The 17-ounce size is generous compared to other craft mixers. I stored it in the refrigerator after opening and noticed no separation after three weeks.
The downside is that the smoked flavor can become repetitive if you use it too often. I found myself wanting a cleaner, simpler syrup for my second round of drinks. This is not a flaw in the product.
It is just a matter of personal preference. If you love smoky drinks, you will finish the bottle quickly.

Smoked Flavor Consistency Bottle to Bottle
Craft mixers can vary between batches because they use real ingredients. I ordered two bottles of Bittermilk No.3 a month apart. Both tasted consistent.
The smoke level was identical, and the acidity was stable. This matters if you are buying a second bottle after enjoying the first. The company is small enough to maintain quality control.
They are based in Charleston, South Carolina. Their bartender background shows in the formulation. I trust this brand more than mass-produced sour mixes that rely on citric acid and artificial flavors.
Pairing Options Beyond Whiskey
Bittermilk No.3 is marketed for whiskey. I tested it with aged rum and mezcal. The mezcal pairing was excellent because the smoke in the mixer complemented the agave smoke.
For a Penicillin riff, you could use mezcal as the base and skip the Islay float entirely. The result is lighter but still complex. I also tried it with sparkling water for a non-alcoholic option.
The syrup is sweet enough to carry a drink without spirits. I would recommend using a smaller pour and adding extra lemon. This versatility makes the bottle useful even if you do not drink whiskey every night.
7. Chivas Regal 12 Year Scotch – Smooth Blended Base
Chivas Regal Scotch Whisky 12 Year – 750ml
750ml bottle
40% ABV
12-year blend
Honey and vanilla notes
Pros
- Smooth and sweet taste with notes of honey
- vanilla and apple
- Great value price point
- Versatile for cocktails or sipping neat
- Approachable for new whisky drinkers
- Silky smooth finish
Cons
- Not as sharp as highland scotch
- Blend may not appeal to single malt purists
Chivas Regal 12 Year is the blended Scotch I recommend most often for Penicillin cocktails. The honey and vanilla notes in the whisky echo the honey-ginger syrup. This creates a cohesive flavor profile.
I tested it against two other blends. It provided the smoothest base for the drink. The 40% ABV is standard.
The 12-year age statement adds a level of refinement that younger blends lack. The 2020 International Spirits Challenge Gold award is well-earned. This is not a Scotch that overwhelms the other ingredients.
It supports the lemon and ginger while adding its own warmth. I have served Penicillin cocktails made with Chivas to people who claim they do not like Scotch. They finished the glass.
The 750ml bottle gives you about 17 cocktails at two ounces per drink. That is a solid return for a bottle that also works for sipping neat or in other mixed drinks. I keep a bottle on my bar cart at all times because it is so versatile.
The finish is silky. There is no harsh burn that would clash with the honey sweetness.
Value for Frequent Cocktail Making
Chivas Regal sits at a sweet spot between quality and cost. You are not paying a premium for rare single malt status. You are getting a 12-year blend that tastes expensive.
I calculated that each Penicillin cocktail uses roughly two ounces of the base spirit. This makes the per-drink cost reasonable for a craft cocktail at home. The bottle is widely available, so you can replace it easily when it runs low.
I order mine online and typically receive it within two days. For someone building a home bar, the availability factor is as important as the flavor.
Approachability for Non-Scotch Drinkers
If you are buying Scotch for a gift recipient who is new to whisky, Chivas Regal is the safest bet. It is smooth and sweet without the medicinal notes that scare some people away from Scotch. The apple and vanilla notes are familiar and comforting.
The smoke is minimal. In a Penicillin, the blended base is only part of the story. The Islay float provides the smoke, so the base can be milder.
Chivas Regal plays that role perfectly. It lets the honey-ginger syrup and the smoky float be the stars while providing a solid foundation.
8. Johnnie Walker Red Label Scotch – Bold Budget Blend
Johnnie Walker Red Label Scotch Whisky – 750ml
750ml bottle
Bold smoky finish
Gold medal winner
Quality oak cask matured
Pros
- Bold
- distinctive smoky flavor
- Great for mixing with ginger ale and lime
- Long
- lingering smoky finish
- Good value for a blended Scotch
- Can be enjoyed neat
- on rocks
- or in cocktails
Cons
- Lids can be thin and sticky
- Some find it too mild for single malt lovers
Johnnie Walker Red Label is the budget-friendly option that still delivers a respectable Penicillin. I tested it as a base alongside Chivas Regal. The difference was noticeable but not dramatic.
The Red Label has a bolder, more assertive character that cuts through the lemon juice effectively. It won a Gold Medal at the 2019 San Francisco World Spirits Competition. This speaks to its quality at this price point.
The smoky finish is longer than Chivas Regal. This adds a pleasant tail to the drink. I found this worked well when I used a lighter syrup like Tippleman’s.
The extra smoke from the base compensated for the milder sweetener. The oak cask maturation gives it a woody depth that younger blends lack. The 750ml bottle is the same size as the others.
The pour cost is lower. If you are making Penicillin cocktails for a party and need to buy multiple bottles, Red Label is the practical choice. I used two bottles for a dinner party of ten people.
Everyone had two cocktails with some left over.
Budget Impact on Overall Kit Cost
When you are building a full Penicillin setup, the Scotch is often the most expensive component. Choosing Red Label for the base keeps your total cost manageable. You can save the premium bottle for the Islay float.
I recommend this strategy for beginners who want to experiment without spending too much on their first bottle. The difference in quality between Red Label and more expensive blends is smaller in a mixed drink than it is when sipping neat. The lemon juice and syrup mask some of the finer distinctions.
You are not sacrificing much by going with a budget option for the base.
Flavor Profile in Mixed Drinks
Red Label performs well in any sour-style cocktail. The bold character means it does not disappear behind the citrus. I tested it in a Penicillin, a Whiskey Sour, and a Hot Toddy.
It worked in all three. The smoke is present but not peaty. It does not clash with the honey.
The finish is slightly drier than Chivas Regal. This makes the drink feel more refreshing. If you prefer a less sweet Penicillin, Red Label is a good base choice.
You can always add a touch more syrup if you want to compensate.
9. Johnnie Walker Double Black Scotch – Peated Smoke Upgrade
Johnnie Walker Double Black Scotch Whisky – 750ml
750ml bottle
40% ABV
Heavily charred oak casks
Double Gold medal
Pros
- Intense smoky flavor with spice
- Deep
- rich character from heavily charred oak casks
- Great as a gift or personal treat
- Accessible alternative to expensive Islay single malts
- Mixes well with soda water and ice
Cons
- Strong smoke flavor may not suit all tastes
Johnnie Walker Double Black is the bridge between blended Scotch and Islay single malts. It is heavily influenced by peaty west coast malts. This shows in the flavor.
I tested it as both the base and the float in a Penicillin. It worked surprisingly well as a two-in-one solution. The 2019 San Francisco World Spirits Competition Double Gold Medal is evidence that this is not just a marketing gimmick.
The heavily charred oak casks give it a depth that Red Label cannot match. When I used it as the base, the drink had a darker, more brooding character. When I used it as the float, the smoke was more integrated than a typical Laphroaig float.
The blend already contains non-peated whisky. This is a good option if you want smoke without the full medicinal intensity of an Islay. The 40% ABV is standard.
The 750ml bottle is the same size as the rest. I find this bottle is best for personal use rather than large parties because the smoke is an acquired taste. At a recent gathering, half my guests loved it.
The other half preferred the Chivas-based version. That polarization is the nature of peated whisky.
Smoke Level Compared to Islay Single Malts
Double Black is smoky, but it is not Laphroaig. The peat is present but polite. The blend includes sweeter grain whisky that rounds the edges.
I would place it at about half the intensity of a true Islay single malt. This makes it a good training wheel for people who are curious about smoke but intimidated by the full peat experience. In a Penicillin, the smoke level is further diluted by the lemon and syrup.
The result is a drink that tastes smoky without being aggressive. I recommend this for anyone who wants to introduce friends to peated Scotch gradually.
When to Use as Base vs. Float
I experimented with using Double Black as both the base and the float in the same drink. The result was too smoky for most people. I enjoyed it.
The better approach is to use it as the base with a lighter float. Or use a mild blend as the base and float Double Black on top. The second option is my favorite.
The mild base gives the drink structure. The Double Black float provides the aroma. You get the smoke on the nose without overwhelming the palate.
This is a technique I learned from a bartender at one of the Denver craft cocktails spots I frequent.
10. Laphroaig 10 Year Single Malt – Classic Islay Float
Laphroaig 10 Year Single Malt Scotch Whisky – 750ml
750ml bottle
10-year Islay single malt
Peat and smoke
World's #1 selling Islay
Pros
- Intense
- powerful smoky and peaty flavor
- Smooth despite the strong flavor
- Unique and complex taste
- Can be enjoyed neat or with a single ice cube
- Loved by peat and smoke enthusiasts
Cons
- Very smoky - not for those who dislike peat
- Polarizing flavor (love it or hate it)
Laphroaig 10 Year is the classic choice for the Penicillin float. It is the world’s best-selling Islay single malt for a reason. The peat smoke is intense, medicinal, and unmistakable.
I pour a quarter ounce over the back of a spoon on top of the finished drink. The aroma hits before the first sip. Reddit users on r/cocktails consistently name Laphroaig as their preferred float whisky.
My testing confirms why. The 10-year age statement gives it enough maturity to smooth the rough edges of the peat. Younger Islay malts can taste harsh.
Laphroaig has a rounded quality that makes the smoke more approachable. I use it exclusively for the float because the full pour would dominate the drink. A small amount is all you need.
The 750ml bottle lasts a long time when used only for floats. I estimate about 60 to 75 Penicillin cocktails per bottle if you use a quarter ounce each time. I also sip it neat on cold nights.
My bottle does double duty. The non-chill filtered expression is the one to look for because it preserves more of the oils that carry the peat flavor.
Acquired Taste Factor for Guests
If you are making Penicillin cocktails for guests who have never tried peated Scotch, you should warn them about the float. Some people love it immediately. Others recoil at the first whiff.
I usually make a test batch without the float and let guests add it themselves if they are curious. The polarizing nature of Laphroaig is part of its charm. It is not a crowd-pleaser in the same way as Chivas Regal.
It is the most authentic choice for a traditional Penicillin. I keep a bottle on hand for myself and for the one friend who always asks for the smoky version.
Price Per Serving as a Float Only
Because you use so little per drink, the cost per cocktail is low. A bottle of Laphroaig is an investment. It stretches further than a base spirit because the pour is tiny.
I calculated that each float costs less than a premium olive would cost in a Martini. This makes the bottle a smart buy even if you only make Penicillin cocktails occasionally. The bottle also works for other smoky cocktails.
I float it on Old Fashioneds, use it in small amounts in Scotch sours, and add a few drops to hot chocolate in winter. The versatility justifies the price for anyone who enjoys the flavor of peat.
How to Choose the Right Penicillin Cocktail Kit
Buying the right combination of tools and ingredients depends on your experience level. Your budget matters too. How often you plan to make this drink is another key factor.
Our team talked to home bartenders and professionals to find the most common decision points. Here is what we learned.
Start with the Right Syrup
The honey-ginger syrup is the soul of a Penicillin cocktail. If you buy one thing, buy a quality syrup. Tippleman’s and Liber & Co. both deliver bar-quality results without the 20 minutes of prep and cleanup that homemade syrup requires.
The forum discussions we reviewed showed that the biggest barrier to making Penicillin cocktails at home is the time it takes to make proper syrup. Consider how much you will use. A 13-ounce bottle makes about 17 cocktails.
If you make one round per week, that is a four-month supply. If you host monthly parties, you might want a larger bottle or a backup. Store opened syrup in the refrigerator and use it within three months.
Pick Your Scotch Wisely
You need two types of Scotch: a blended whisky for the base and a peated Islay for the float. Chivas Regal 12 Year is the best all-around base for beginners. Johnnie Walker Red Label is the practical choice for large gatherings.
Laphroaig 10 Year is the non-negotiable float for purists. Johnnie Walker Double Black is the compromise if you want smoke without the full Islay intensity. The base Scotch matters more than most people think.
It provides the backbone of the drink. A cheap blend can taste thin. The float is about aroma and a hint of flavor.
A small pour of quality peated whisky is worth the cost. Reddit users consistently report that the float is what separates a good Penicillin from a great one.
Consider Your Shaker Style
A cobbler shaker like the KITESSENSU is the easiest starting point. The built-in strainer and simple three-piece design make it forgiving for beginners. The Mixology & Craft set adds tools that you will eventually want anyway.
The Art of Craft Boston set is for people who plan to make cocktails regularly. They want the speed and capacity of a professional setup. The shaker is not the most important purchase for a Penicillin.
It does affect the texture. A good seal creates better dilution and aeration. A poor seal leaks and under-dilutes the drink.
Any of the three shakers we recommend will handle this drink well. Choose based on your overall bartending goals.
Think About Batch Size
If you plan to serve Penicillin cocktails at a party, you can batch the base ahead of time. Mix the blended Scotch, syrup, and lemon juice in a pitcher. Then shake individual portions with ice and add the float fresh.
The base mixture holds for a few hours in the refrigerator. Do not add the Islay float until you are ready to serve. For a party of 20 people, you need about 40 ounces of blended Scotch, 20 ounces of syrup, and 20 ounces of lemon juice.
One bottle of Laphroaig will cover the floats with plenty left over. The Reddit community suggests making 30% extra base. People tend to pour heavier at home than professionals do at bars.
Frequently Asked Questions
What is the history of the penicillin cocktail?
The Penicillin cocktail was created by Sam Ross in 2005 at the Milk & Honey bar in New York City. It is a modern classic that combines blended Scotch, honey-ginger syrup, lemon juice, and a float of peated Islay Scotch. The drink became one of the most popular cocktails of the 21st century and is now served at bars worldwide.
What is the best Scotch whiskey for Penicillin?
The best base Scotch is a smooth blend like Chivas Regal 12 Year or Johnnie Walker Red Label. For the smoky float, Laphroaig 10 Year is the classic choice. Johnnie Walker Double Black works as a middle ground if you want smoke without the full intensity of an Islay single malt.
What is the difference between gold rush and penicillin cocktails?
A Gold Rush uses bourbon, honey syrup, and lemon juice without the smoky float. A Penicillin uses blended Scotch, honey-ginger syrup, lemon juice, and a float of peated Islay Scotch. The Penicillin is essentially a smoky, Scotch-based variation of the Gold Rush.
Can you batch a penicillin cocktail?
Yes, you can batch the base by mixing blended Scotch, honey-ginger syrup, and lemon juice in a pitcher. Shake individual portions with ice before serving, and add the Islay float fresh. The base mixture holds for a few hours refrigerated but should not be batched with the float.
Is Penicillin a strong cocktail?
A standard Penicillin contains two ounces of blended Scotch plus a quarter ounce of Islay float, making it moderately strong. The lemon juice and honey-ginger syrup balance the alcohol, so it does not taste as potent as it is. It is comparable to a Whiskey Sour in strength.
