13 Best Groomsmen Flask Sets (September 2026): Expert Reviews

Finding the right gift for your wedding party is harder than most people admit. You want something the guys will actually use, not just smile at and shove in a drawer. That is exactly why groomsmen flask sets have been a go-to gift for decades. They are practical, personal, and with the right engraving, they become a keepsake your crew will hold onto long after the reception ends.

I have spent weeks comparing flask sets across every price range and configuration for this guide. From single flasks with leather wraps to full sets of 12 for large wedding parties, I looked at build quality, engraving precision, leak-proof reliability, and what real customers actually say after using them. What I found surprised me in a few places, especially when it came to which budget sets punched above their weight class.

This roundup covers 13 groomsmen flask sets that deliver real value in 2026. Whether you need an affordable option for a big crew or a premium personalized set for your closest friends, there is a match here. I also included a buying guide that breaks down materials, sizes, and what to fill the flasks with, because nobody wants to hand out empty gifts.

Top 3 Picks for Best Groomsmen Flask Sets

Best Groomsmen Flask Sets in 2026

1. Personalization Lab Set of 6 Flask – Best Overall Personalized Flask Set

I picked the Personalization Lab set as my top choice because it nails the balance between quality, customization, and presentation. This is a set of 6 custom engraved 6oz stainless steel flasks, and the engraving is free, which immediately sets it apart from competitors that charge extra for personalization. When I looked at what customers were saying, the feedback was overwhelmingly positive, especially about how fast the orders ship out.

The flasks themselves feel solid in hand. They use a curved-edge design that gives them a more refined look compared to the boxy flasks you sometimes see at this tier. You can customize each flask with a name, title, and the whole set comes packaged nicely if you opt for the gift box version. That gift box includes a funnel, which is a small detail that makes a big difference when your groomsmen are trying to fill these at a bachelor party.

With over 1,700 reviews and a 4.8-star average, this set has earned its reputation. Customers specifically praise the engraving quality and how quickly the company turns around personalized orders. When there are minor issues with spacing on the engraving, the seller is known for correcting them fast. That level of customer service matters when you are ordering gifts on a wedding timeline.

On the downside, the 6oz capacity is smaller than the 8oz standard you see on many competitors. If your groomsmen are serious whiskey drinkers, they might wish for a larger flask. The finish can also show scratches over time if the flasks get tossed in a bag with keys or other metal objects.

Who should buy this set

This is the ideal pick for grooms who want a polished, ready-to-gift option for a standard wedding party of 6. The free engraving and gift box option save you time and effort. It works best for wedding parties where you want every groomsman to have a matching, personalized flask without having to coordinate separate orders.

What to watch out for

The 6oz size means about 4 standard shots per fill. If your crew prefers larger flasks or you are planning a long bachelor weekend where bigger capacity matters, you might want to look at the 8oz options in this roundup instead. Also, order at least 3 weeks before your wedding to allow for engraving and shipping time.

2. GENNISSY 8oz Hip Flask – Best Single Flask Gift

The GENNISSY 8oz hip flask is the single-flask option I recommend most often, and it comes down to two things: accessories and build quality. This flask includes a funnel and three 0.5oz mini shot glasses, so each groomsman gets a complete drinking kit right out of the box. The brown PU leather wrap gives it a premium feel that looks far more expensive than what you actually pay.

Under that leather wrap is 304 (18/8) food-grade stainless steel, which is the same material used in commercial kitchen equipment. The cap uses high-frequency welding technology and thickened threading to create a genuinely leak-proof seal. I read through hundreds of reviews, and the leak-proof claim holds up consistently. People carry these in jacket pockets and bags without issues.

With over 5,300 reviews and a 4.5-star rating, this is one of the most popular flasks on the market. Customers love the value proposition. You get the flask, three cups, and a funnel for what many competitors charge for the flask alone. The leather wrap is available in several variants including black, navy blue, and a US flag design, so you can match the style to each groomsman’s personality.

There are a couple of things to know before ordering. The flask needs a thorough wash before first use to remove manufacturing residue, which several reviewers mentioned. The included funnel has sharp edges, so handle it carefully. And the shot glasses are genuinely tiny at 0.5oz each, more for tasting than actual pours.

Who should buy this flask

This is perfect for grooms buying individual gifts for each groomsman rather than a matched set. If your wedding party ranges from 3 to 8 people, ordering these individually gives you flexibility on quantity. It is also a great pick if you want to give each guy something different while keeping the overall gift consistent.

What to watch out for

The mini cups are really small at 0.5oz. If you want actual shot glasses, you will need to buy those separately. Also, give yourself time to clean each flask thoroughly before filling them, as the manufacturing residue is a common complaint in the first-use experience.

3. Stepdiy Set of 5 Personalized Flasks – Best for Mid-Size Wedding Parties

The Stepdiy set of 5 hits a sweet spot that most competitors miss. Many flask sets come in quantities of 4, 6, 8, or 12, but 5 is actually the most common wedding party size. This set fills that gap with high-quality 304 stainless steel flasks that feature permanent laser engraving. The engraving is sharp, deep, and will not fade over time, which is exactly what you want in a keepsake gift.

Each flask holds 8oz, which gives your groomsmen about 5-6 standard shots. The black matte finish looks sleek in photos and in person, and there is also a gold variant if you want something that stands out more. The customization allows you to add names and titles for each groomsman, making each one personal while keeping the set cohesive.

Customer feedback is strong across the board with a 4.8-star average from over 600 reviews. Multiple reviewers specifically mention that the engraving quality exceeded their expectations. The customer service team is also responsive, typically getting back within 24 hours if there are any issues with an order.

The main concern I found in reviews is that the flask walls feel thinner than some competitors. This keeps the weight down for portability but means they can dent if dropped on a hard surface. A few customers also noted minor packaging issues, though the flasks themselves arrived intact in nearly every case.

Who should buy this set

This is the go-to for grooms with a 5-person wedding party who want personalized 8oz flasks without paying for extras they do not need. The laser engraving quality makes these feel special enough for the occasion while the larger capacity keeps them practical for actual use.

What to watch out for

The thinner walls mean these are better suited as display and occasional-use flasks rather than everyday carry items. If your groomsmen are the type to take a flask camping or fishing regularly, consider a heavier-duty option instead.

4. BALABALA 12-Piece Flask Set – Best Value Bulk Set

If you have a large wedding party or are planning a bachelor party with a big group, the BALABALA 12-piece set is hard to beat on value. You get 12 matte black 8oz flasks and 12 matching funnels, all for a price that works out to just a few dollars per flask. Despite the low per-unit cost, these flasks use food-grade stainless steel that is BPA-free and anti-corrosion.

What makes this set particularly appealing for wedding use is that the matte black finish takes laser engraving beautifully. Several reviewers who run engraving businesses specifically mentioned these as their go-to blanks for custom work. The flasks are laser welded and air-pressured to be leak-proof, and that claim holds up based on the consistent feedback from over 1,200 customers.

The 8oz capacity is the standard sweet spot for hip flasks, holding enough for several pours without being bulky. Each flask measures 0.8 inches deep by 3.8 inches wide by 5.38 inches tall, which fits comfortably in most jacket pockets. The set is versatile enough for wedding parties, bridesmaid gifts, or even corporate events.

The trade-off for the low price is that these do not feel as premium as individual flask gift sets. There is no leather wrap, no gift boxes, and no shot glasses included. A few customers noted that the flasks can look a bit plain without engraving. If you want these to feel like proper gifts, plan to add your own personalization.

Who should buy this set

This is the clear winner for large wedding parties of 10-12 people where budget matters. It is also excellent for grooms who want to add their own custom laser engraving locally. If you are buying for both groomsmen and bridesmaids, the quantity and neutral design work perfectly.

What to watch out for

Without personalization, these flasks look fairly basic. Budget for engraving or plan to dress them up with your own gift packaging. The funnels included are functional but nothing special.

5. United Craft Supplies Rustic Flask Set – Best Rustic Style

The United Craft Supplies rustic flask set stands out because of its leatherette covering, which gives each flask a warm, textured look that photographs beautifully for wedding gifts. Under the vegan leather exterior is rust-proof stainless steel, and the combination creates a flask that feels genuinely premium without the premium price tag. The laser engraving cuts cleanly through the leatherette for a personalization that looks professionally done.

What impressed me most about this set is the customer service. United Craft Supplies is a USA-based company that specializes in wedding gifts, and it shows in how they handle orders. When I read through the reviews, multiple customers mentioned that the company fixed engraving errors quickly and even sent replacements when there were issues with the clasp mechanism on the cap.

The 6oz capacity keeps these flasks compact and easy to carry. The never-lose cap design means the screw top is attached to the flask body, so it cannot be misplaced during a night out. Available in sets of 1, 3, or 6, you can match the quantity to your wedding party size without buying extras you do not need.

The rustic design aesthetic makes these flasks feel like they belong at a barn wedding or an outdoor ceremony. They have that vintage, handcrafted look that pairs well with wooden decor and burlap accents. However, the 6oz capacity is smaller than the 8oz standard, which means fewer pours per fill.

Who should buy this set

Perfect for rustic, barn, or outdoor weddings where the gift should match the overall aesthetic. The leatherette finish adds a tactile quality that bare stainless steel lacks. Great for grooms who want a thoughtful, personalized gift that looks like it came from a specialty shop.

What to watch out for

The 6oz size holds about 4 shots, so these are more of a symbolic gift than a serious drinking vessel. Check each flask when it arrives, as a small percentage of customers reported clasp issues that required replacement.

6. GliSun 8-Piece Flask Set – Best Budget Set with Accessories

The GliSun 8-piece set delivers more accessories than almost any other option in this price range. You get 8 matte black 8oz flasks, 8 stainless steel shot cups, and 8 funnels. That is a complete gift package for each groomsman, all at a price that makes sense for larger wedding parties. The 304 food-grade stainless steel construction is the same material used in much more expensive flasks.

What makes this set work well for groomsmen gifts is that each flask comes with its own cup and funnel. Your groomsmen can pour and share drinks without scrambling for glasses. The leak-proof design uses laser welding and air pressure testing, which is impressive at this price point. Over 100 customers bought these in the last month alone at the time of my research.

The matte black finish looks professional and takes laser engraving well, according to multiple reviewers who had these custom-engraved for their weddings. Each flask measures 5.35 x 3.6 x 1 inches, which is compact enough for a jacket pocket or a small gift bag. The set is suitable for whiskey, bourbon, vodka, and other spirits.

The main drawback is that the black finish scratches relatively easily. If these flasks get jostled around in a bag with keys or coins, you will see marks over time. The included shot cups are also on the small side, more suitable for tasting pours than full shots.

Who should buy this set

Ideal for wedding parties of 8 who want a complete gift package without paying premium prices. The included cups and funnels mean you do not need to buy anything extra to make these feel like proper gifts. Also great for couples who want to give matching gifts to both groomsmen and bridesmaids.

What to watch out for

The finish durability is the main concern. If you want these to look pristine for years, consider the stainless steel-only versions rather than the coated black ones. The shot cups are functional but small.

7. My Personal Memories Custom Flask Set – Best Multi-Line Engraving

My Personal Memories offers the most flexible engraving options of any set in this roundup. Each flask supports three separate lines of custom text, which means you can include a name, a title like “Best Man” or “Groomsman,” and a date or short message on each one. The silver engraving on the black matte background creates a sharp contrast that photographs beautifully for wedding memories.

The flexibility extends to quantity as well. You can order anywhere from 1 to 8 flasks, making this a good choice whether you have 2 groomsmen or 8. The gift box option adds a funnel, 4 shot glasses, and a presentation box for an upgraded gifting experience. Each flask holds 6oz of liquid in a compact rectangular shape.

Customers consistently praise the engraving quality and how well it holds up over time. Multiple reviews mention that the engraving shows no signs of fading even after months of use. The processing and delivery times are also noted as being fast, which is important when you are ordering personalized gifts on a wedding deadline.

The paint finish is the weak point. Several customers reported that the black matte coating can scratch if the flask rubs against keys, coins, or other metal objects in a pocket or bag. When the paint chips, the metal underneath has a bronze tint rather than silver, which can look noticeable on a black flask.

Who should buy this set

Best for grooms who want detailed personalization beyond just a name. The three-line engraving lets you include meaningful details like a wedding date, a personal message, or each person’s role in the wedding. The flexible quantity makes it work for any party size.

What to watch out for

These flasks look great but the painted finish is not the most durable. If your groomsmen plan to carry these regularly, consider that the coating may show wear over time. The engraving itself is permanent, so even if the paint wears, the personalization will remain.

8. Tebery Set of 4 Flask Set – Best Budget 4-Pack

The Tebery 4-pack is the set I would reach for if I had a smaller wedding party and wanted to keep costs reasonable without sacrificing quality. You get 4 matte black 8oz stainless steel flasks and 4 funnels, each individually packaged so they are ready to hand out as gifts. The screw-down cap is attached to the flask body, which prevents the common problem of losing caps at a party.

These flasks have a kidney-shaped design that fits the curve of your body better than rectangular flasks, making them more comfortable to carry in a pocket. The stainless steel is rust and corrosion resistant, and the matte black coating provides a clean surface that works well for laser engraving. Multiple reviewers specifically mentioned taking these to a local engraver for customization.

With nearly 1,400 reviews and a 4.7-star average, the Tebery set has proven itself with a large customer base. The value proposition is strong. Reviewers consistently mention that the flasks look and feel more expensive than they actually are. The individual packaging is a nice touch that saves you from buying separate gift boxes.

The main quirk is that the actual capacity is slightly less than the advertised 8oz. Several reviewers measured and found it holds about 7.1 to 7.2 ounces. There are also occasional reports of receiving fewer funnels than flasks in a pack, so it is worth checking when your order arrives.

Who should buy this set

Perfect for wedding parties of 4 who want a budget-friendly option that does not feel cheap. The individual packaging makes these easy to distribute as gifts. Also great if you want to add your own engraving locally to give each flask a personal touch.

What to watch out for

The slightly reduced capacity means each flask holds about one less shot than a true 8oz flask. Check the funnel count when your order arrives, as a few customers received incomplete sets.

9. United Craft Supplies Chestnut Flask Set – Best Premium Leatherette

The Chestnut version of the United Craft Supplies flask set is the premium option for grooms who want their groomsmen gifts to feel truly special. The Chestnut vegan leather cover has a warm, rich tone that stands out from the standard black or brown options you see everywhere. Each flask in this set of 6 gets laser-engraved with your custom text, cutting cleanly through the leatherette for a personalization that looks high-end.

Under the leather exterior is a stainless steel core that is built to last. The never-lose cap design keeps the screw top tethered to the flask body. You can choose from 4 leatherette colors including Black, Grey, Rustic, and this Rawhide/Chestnut finish. The set is available in quantities of 1, 3, or 6 to match different wedding party sizes.

Customers who chose this set for their weddings praise the fast shipping, even when ordering on tight timelines close to the wedding date. The engraving quality gets consistent positive feedback. Several reviewers mentioned that the leatherette covering looks and feels realistic enough that people assumed it was genuine leather.

The main consideration is the price. This is one of the more expensive options per flask in the roundup, and it is still vegan leather rather than the real thing. A few customers noted that upon close inspection, the synthetic nature of the leatherette is apparent, though most felt it looked convincing at gift-giving distance.

Who should buy this set

Ideal for grooms who want a distinctive, upscale look for their groomsmen gifts. The Chestnut color is unique and photographs well. Best for wedding parties of 6 where the budget allows for a premium gift that makes a strong impression.

What to watch out for

This is vegan leather, not genuine leather, so set your expectations accordingly. The 6oz capacity is on the smaller side. The higher price per flask means this is best for smaller, close-knit wedding parties rather than large groups.

10. CARLOTA Hip Flask Gift Set – Best Single Flask Gift Box

The CARLOTA flask gift set is the most complete single-flask package I found. It comes in a presentation gift box with the 8oz flask, 2 mini shot cups, and a funnel all included. The flask has a black PU leather cover over 18/8 (304) stainless steel, giving it a classic look that works as a gift for any groomsman. The lifetime warranty is an unusual bonus at this price point.

The leak-proof design uses a hinged screw cap that stays attached to the flask. This is a thoughtful design choice because it eliminates the most common flask problem: losing the cap at a party or on the trail. The laser-welded hinge construction feels sturdy and holds up to regular use based on customer feedback.

With nearly 1,300 reviews and a 4.6-star average, this set has built a strong reputation. The gift box presentation gets consistent praise from customers who ordered these for wedding parties. Multiple reviewers mentioned that the box looks nice enough to hand directly to someone without additional wrapping. The lifetime warranty adds confidence that the company stands behind the product.

There are some inconsistencies to be aware of. A few customers reported that the product they received did not exactly match the listing photos, particularly in the leather texture and stitching. The shot glasses can have quality variations, with some arriving with rough edges. These are minor issues but worth knowing about when you are buying gifts.

Who should buy this set

Great for grooms buying individual gifts for 3-5 groomsmen who want each flask to arrive gift-ready. The included gift box saves time and effort. The lifetime warranty makes this a smart pick for groomsmen who will actually use their flasks regularly.

What to watch out for

Check each set when it arrives for quality consistency, especially the shot glasses. If you need these to be identical for a matched set, order them all at once from the same batch to minimize variation.

11. Rtteri Tuxedo Flask Set – Best Themed Design

The Rtteri tuxedo flask set brings a fun theme that ties directly into the wedding aesthetic. Each of the 6 flasks features a tuxedo pattern design in black, with one flask labeled “BEST MAN” and five labeled “GROOMSMAN.” It is a small detail, but it adds a layer of thoughtfulness that plain flasks lack. The 8oz capacity gives each groomsman enough room for a proper pour.

The tuxedo design is printed directly onto the stainless steel surface in matte black. The flasks measure 5.43 x 3.62 inches, which is standard for 8oz hip flasks and fits easily into jacket pockets. The stainless steel construction is basic but functional, with no leaks reported by most customers who tested them.

Customer feedback is generally positive, with most reviewers appreciating the themed design and the affordable price for a set of 6. Over 50 customers purchased these in the last month at the time of my research, indicating steady demand for wedding season. The concept of having distinct BEST MAN and GROOMSMAN labels saves you from having to add that personalization yourself.

The quality concerns are worth noting. Several reviews mention that the flasks feel lightweight and somewhat cheap in hand. There are also reports of an initial oil or manufacturing smell that requires washing before first use. The tuxedo design is a printed pattern rather than engraved, so it may wear over time with heavy use.

Who should buy this set

Best for grooms who want a fun, themed gift that matches the wedding vibe without spending a lot. The pre-printed BEST MAN and GROOMSMAN labels are a convenient touch. Works well for casual weddings where a playful gift fits the tone.

What to watch out for

These are budget flasks with a fun design, not premium keepsakes. The printed tuxedo pattern may fade with heavy use. Wash them thoroughly before gifting to remove any manufacturing residue, and consider filling them with a nice bourbon to elevate the presentation.

12. GENNISSY Chess Flask Gift Set – Best Novelty Gift Set

The GENNISSY chess flask gift set is the most unique option in this roundup, and it is perfect for that one groomsman who loves both whiskey and board games. The set includes an 8oz stainless steel hip flask, a wooden chess board, 4 metal shot cups, a funnel, and a brown leather carrying case that holds everything together. It is a gift that gives your groomsman something to do while enjoying his drink.

The flask itself is the same quality GENNISSY construction as the standalone model, with 100% leak-proof sealing and food-grade stainless steel. The leather case folds out into a chess board, which is a clever space-saving design. The set includes all the chess pieces and the shot cups nest inside the case for storage.

Customers love the concept and presentation of this set. With 481 reviews and a 4.6-star average, the feedback is solid. Most buyers purchased this as a gift for Father’s Day, birthdays, or groomsmen gifts. The “wow” factor when the recipient opens the leather case and sees the chess board inside is something multiple reviewers mentioned.

The main trade-off is size. Everything in this set is compact, which is necessary for portability but means the chess board and pieces are smaller than a standard set. The shot glasses are on the tiny side. A few customers noted that the chess board was not perfectly square, though it is still playable. This is a novelty gift first and a serious chess set second.

Who should buy this set

Perfect for the groomsman who appreciates a good game of chess along with his whiskey. This makes an excellent standalone gift for your best man or a particularly close friend in the wedding party. The leather case presentation makes it feel like a special occasion gift.

What to watch out for

Manage your expectations on the chess board quality. It is functional but not tournament-grade. If your groomsman is a serious chess player, he will appreciate the thought more than the board itself. Focus on the flask and presentation quality as the real value here.

13. Yaomiao Complete Groomsmen Gift Set – Best All-In-One Proposal Kit

The Yaomiao complete groomsmen gift set is the most comprehensive package in this roundup, and it is designed specifically for grooms who want to handle everything in one order. Each of the 8 kits includes an 8oz stainless steel flask, a shot glass, a funnel, a credit card bottle opener, and a black gift box with raffia grass shred fill. You literally open the box, fill the flask, and hand it to your groomsman.

The attention to presentation is what sets this apart. The raffia grass shred fill inside each gift box creates an upscale look that you usually only see from specialty gift shops. The credit card bottle openers are a practical addition that your groomsmen will use long after the wedding, since they fit in a wallet. The black finish on all items makes this set look cohesive and professional.

Customer feedback is overwhelmingly positive with a 4.8-star average. Reviewers love the convenience of having everything arrive together in gift-ready packaging. Multiple customers mentioned that these looked far more expensive than what they actually paid. The set is particularly popular for groomsmen proposals, where you ask your friends to be in the wedding party.

The main consideration is stock availability. At the time of my research, only about 20 units were left in inventory, which suggests this set sells quickly during wedding season. The items are also not dishwasher safe, as the coating can peel with high-heat washing. Hand wash only to keep them looking good.

Who should buy this set

Best for grooms planning a groomsmen proposal who want everything handled in a single purchase. The all-inclusive nature of this set means no additional shopping or packaging needed. Ideal for wedding parties of 8 who appreciate practical, giftable items.

What to watch out for

Stock can be limited, especially during peak wedding season. Order early to secure your set. The dishwasher warning means your groomsmen need to know to hand wash only. The flasks are also ideal candidates for custom engraving, so budget for that if you want to add personalization.

What to Look for in a Groomsmen Flask Set

Choosing the right groomsmen flask sets comes down to matching your wedding party size, budget, and personalization expectations. After comparing all these options, here are the key factors that actually matter when making your decision.

Material: Stainless Steel vs Leather vs Leatherette

Stainless steel is the standard for a reason. It is durable, rust-resistant, and does not impart flavors into the liquor. All 13 sets in this roundup use stainless steel as the core material. The question is really about the exterior finish.

Bare stainless steel or matte black coatings are the most versatile and take engraving well. Leather and leatherette wraps add a premium feel and are more comfortable against the body when carrying in a pocket. Genuine leather is rare at these prices; most wrapped flasks use PU leather or leatherette, which still looks great but will not age the same way real leather does.

For wedding gifts, leatherette wraps from United Craft Supplies offer the best balance of appearance and durability. For grooms on a tight budget, bare or coated stainless steel from brands like BALABALA and Tebery delivers the best value.

Flask Size: 6oz vs 8oz

This is a bigger decision than most people realize. A 6oz flask holds about 4 standard 1.5oz shots, while an 8oz flask holds 5-6 shots. For a wedding gift that may sit on a shelf more than it gets used, 6oz is fine. For groomsmen who will actually carry and drink from their flasks, 8oz is the better choice.

The trade-off is that 6oz flasks are more compact and easier to pocket. They also tend to look a bit more refined. The Personalization Lab and United Craft Supplies sets use 6oz, while the BALABALA, Stepdiy, and most budget options use 8oz.

Personalization Options

Engraving is what separates a generic gift from something meaningful. Most sets in this roundup offer some form of personalization, but the quality varies. Laser engraving is the gold standard because it cuts into the metal permanently and will not fade. Paint-based or printed designs look good initially but can wear off over time.

The best engraving options come from dedicated wedding gift companies like Personalization Lab, Stepdiy, and United Craft Supplies. Bulk sets like BALABALA and Tebery work great if you want to have them engraved locally, since the matte black finish takes laser work beautifully.

Set Size and Party Matching

Buy a set that matches your wedding party size. Having extra flasks is wasteful, and coming up short is awkward. The options in this roundup cover every party size from 1 to 12. Sets of 4 (Tebery), 5 (Stepdiy), 6 (Personalization Lab, Rtteri, United Craft), 8 (GliSun, Yaomiao), and 12 (BALABALA) give you plenty of choices.

Accessories and Presentation

The difference between handing someone a bare flask and handing them a flask in a gift box with accessories is significant. Sets like the Yaomiao and CARLOTA come with complete packaging that makes the gifting moment feel special. The Yaomiao set even includes raffia grass shred in the boxes for a professional presentation.

Shot glasses, funnels, and bottle openers are the accessories worth having. Funnels are essential for actually filling the flasks without spilling. Shot glasses turn a solo drinking vessel into something shareable. Bottle openers are practical items your groomsmen will use beyond the wedding.

What to Fill Your Groomsmen Flasks With

Handing over an empty flask feels like giving someone an empty picture frame. Filling each flask with a quality spirit takes the gift to another level. Here are the best options based on what pairs well with a stainless steel flask.

Bourbon is the classic choice. Something like Buffalo Trace, Woodford Reserve, or Maker’s Mark fills an 8oz flask with 5 generous pours and tastes great straight. Whiskey (Irish or Scotch) is equally appropriate, with Jameson or Johnnie Walker being crowd-pleasing choices. For groomsmen who prefer lighter spirits, a good gin like Hendricks or a quality tequila like Herradura works well. Avoid cream liqueurs or anything sugary, as they are hard to clean from a flask.
