A wedding bar shopping list for 100 guests is not just a bottle count — it's a buying plan. The drinks are the easy part. What actually wrecks a DIY bar is the second half of the list: the mixers nobody ordered, the garnish tray that never got built, the 60 extra pounds of ice someone has to run out and buy at 7 p.m., and the returned-bottle policy you didn't ask about at checkout.

This guide turns the standard 100-guest quantities into an actual shopping trip: which aisle, which pack size, which store, which week — plus a printable checklist you can carry into Costco. If you still need the underlying drink math explained step by step, start with our guide to how much alcohol to buy for a 100-guest wedding; this page assumes that math and takes it to the register.

The Numbers Behind the List

Everything below comes from one baseline: a 5-hour reception with 100 guests, about 70% of whom drink. That produces roughly 350 drinks. Split the classic way — 40% beer, 40% wine, 20% cocktails — you're buying toward these targets:

• 140 beers → 6 cases of 24 (or one half-barrel keg plus two cases)
• 140 glasses of wine → 28 bottles at 5 glasses per 750ml bottle
• 70 cocktails → 5 × 750ml spirit bottles at about 17 pours each
• 12–13 sparkling bottles for a toast (8–10 flutes per bottle)
• 150–200 lbs of ice, 6–8 liters of mixers, and a garnish tray

One number to set first: your real headcount, not your invite list. Only 75–85% of invited guests typically attend, so if you mailed 120 invitations you're really planning a bar for about 100. Lock that number down with the wedding guest list calculator before you order anything perishable.

The Wedding Bar Shopping List for 100 Guests, Aisle by Aisle

Shopping by aisle keeps you from wandering the store twice. Here's the 100-guest list grouped the way a store is laid out.

Aisle 1 — Beer (6 cases)

• 4 cases of a crowd-pleaser lager or light beer — this is two-thirds of your beer volume, so buy the one your relatives will actually drink
• 1 case of an IPA or local craft for the guests who care
• 1 case of a non-alcoholic beer or light option — it disappears faster than you expect
• Cans, not bottles, if your venue allows them: lighter to haul, safer on a dance floor, and cheaper to recycle

Aisle 2 — Wine (28 bottles + sparkling)

• 16–17 bottles of white (Sauvignon Blanc, Pinot Grigio, Chardonnay)
• 11–12 bottles of red (Pinot Noir and Cabernet are the safe pair)
• 12–13 bottles of Prosecco or Cava for the toast — a toast pour is small, and almost nobody can tell budget sparkling from Champagne in a flute
• Buy by the case where you can: 12-bottle cases usually earn a 10–15% discount, and case buying is what makes the return policy work in your favor

Aisle 3 — Spirits (5 bottles, two signature cocktails)

• 2 × 750ml vodka — the broadest-appeal base for a signature drink
• 1 × 750ml whiskey or bourbon
• 1–2 × 750ml of whatever your second signature drink needs (tequila, gin, or rum)

Resist the 10-bottle open bar. Curating down to two signature cocktails plus beer and wine is the single biggest saving on the list, and it makes your quantities predictable instead of guesswork. A full open bar quote is usually a per-person package anyway — compare it fairly using a catering calculator alongside your bar numbers.

Aisle 4 — Mixers (6–8 liters)

• Club soda and tonic water — 2 liters each
• Ginger ale or ginger beer — 1 liter
• Cranberry and orange juice — 1.5–2 liters combined
• Fresh citrus juice if you're batching cocktails the day before (bottle it, don't squeeze it on-site)

Mixers are the cheapest insurance on the list. Running out of tonic at 9 p.m. turns a good bar into a bad one for about $4 of product.

Aisle 5 — Garnishes

• 10–12 lemons and 10–12 limes, plus a handheld citrus cutter
• Maraschino cherries, cocktail olives, and a bunch of fresh mint
• Coarse salt and sugar for rims, plus fresh fruit for a mocktail station
• Budget $25–$50 for the whole garnish run — and prep it the morning of, not mid-reception

Aisle 6 — Ice (150–200 lbs)

• Ice for drinks and coolers: 1.5–2 lbs per guest, or 150–200 lbs
• Bagged ice usually runs $2–$4 per 10-lb bag, so 15–20 bags is $40–$80
• Add a few blocks or frozen water bottles to keep bottles cold without turning them into soup

Aisle 7 — Bar Supplies & Glassware

• 300+ cups (about 3 per guest) — compostable disposables are the low-stress choice; rented glassware must come back rinsed and counted
• Cocktail napkins and paper towels, plus trash and recycling bags
• Straws, stirrers, cocktail picks, and a couple of bottle openers and wine keys
• If you're batching: a jigger, a shaker, a large pitcher or beverage dispenser, ice tongs, and an ice bucket
• Coolers, tubs, or a wheeled cart to move it all — the item most couples forget to bring to the venue

Aisle 8 — Non-Alcoholic (for the other 30 guests)

• 2–3 gallons of lemonade or a mocktail base
• Assorted sodas, sparkling water, and plenty of still water
• A pitcher and glassware that makes the mocktail look deliberate, not like an afterthought

Roughly 30 of your 100 guests won't drink alcohol. A mocktail station that costs under $100 will be one of the most-remembered details of the night — and it keeps your bar line shorter for everyone else.

Mixers, Garnishes & Ice — The Forgotten Third

Ask any bartender what ruins a DIY wedding bar and the answer is never the vodka. It's the support items. Three rules cover almost all of it:

1. Headcount the ice, not the drinks. 1.5–2 lbs per guest, and understand that roughly a third is for the coolers, not the glasses. If you're renting, check whether the venue provides any ice at all — many don't.
2. Buy mixers at a 20% buffer. Mixers don't spoil your return window the way opened bottles do, and an under-mixed bar is more noticeable than an over-stocked one.
3. Prep garnishes in bulk, in advance. Pre-cut citrus dries out, so cut two-thirds the morning of and keep the rest whole as backup. Same logic for batching signature cocktails: pre-batch the base, but add the ice and soda at the bar.

Where to Shop for Each Item

Different items belong at different stores. Splitting the trip by category is worth the extra stop, because it's where the real savings come from.

Two questions to ask at checkout, every time: "Do you take returns on unopened alcohol?" and "Is there a case discount?" Those two answers can move your bar bill by $100–$200 and are the whole reason to buy wine and beer by the case instead of by the bottle.

Printable Wedding Bar Shopping List for 100 Guests

Print this, or copy it into your notes app. It's the same list as above, condensed to quantities you can tick off in the store.

• ☐ 4 cases lager / light beer (24-packs)
• ☐ 1 case IPA or craft beer
• ☐ 1 case non-alcoholic beer
• ☐ 16–17 bottles white wine (or 1.5 cases)
• ☐ 11–12 bottles red wine
• ☐ 12–13 bottles Prosecco or Cava
• ☐ 2 bottles vodka · 1 bottle bourbon · 1–2 bottles second spirit
• ☐ 2 L club soda · 2 L tonic · 1 L ginger ale · 2 L juices
• ☐ 12 lemons · 12 limes · cherries · olives · mint · rimming salt & sugar
• ☐ 150–200 lbs ice (15–20 bags) + blocks for coolers
• ☐ 300+ cups · cocktail napkins · straws · stirrers · openers · wine keys
• ☐ Jigger · shaker · dispenser · ice tongs · ice bucket · coolers or tubs
• ☐ 2–3 gallons mocktail base · sodas · sparkling water · still water
• ☐ Trash and recycling bags · wheeled cart for load-in

If your budget runs tight, the honest answer is to cut variety, never quantity. Two beer styles instead of four, one signature cocktail instead of two, and no full spirits bar — guests notice an empty cooler, but nobody has ever complained that the beer selection was too small.

When to Buy: A 4-Week Timeline

Buying in the right order protects both freshness and your return window. Work backwards from the date:

• 4 weeks out: confirm in writing that your venue allows outside alcohol, ask about corkage fees and glass rules, and settle your final headcount estimate.
• 3 weeks out: order spirits and any special-order wine. This is also when you lock your two signature cocktail recipes so the shopping list is final.
• 2 weeks out: buy wine by the case and confirm the return policy in writing. Wine keeps; your ability to return it may not.
• 1 week out: buy beer (freshness matters), order bulk ice delivery, and purchase all cups and bar supplies so nothing is sold out the day before.
• 2 days out: buy garnishes and fresh juice, and start chilling only what you expect to pour in the first few hours.
• Day before: pick up the ice, stage the coolers and dispensers, and pack everything into the vehicle by category.

Fund the whole thing deliberately rather than in one scary week — a monthly set-aside is much easier to swallow. Work out the payment plan with the wedding savings calculator, and if the bar is competing with other line items, run the trade-offs in the wedding budget calculator.

What the Whole Bar Costs by Aisle

For context: the average US wedding runs about $34,200 in 2026 (The Knot Real Weddings Study), and the bar typically claims 8–12% of that. Here's how a DIY 100-guest bar breaks down by aisle:

Compare that to a venue open bar package at $25–$60 per person, which is $2,500–$6,000 for the same 100 guests. Self-supplying can save 30–50% — but only if you budget the items couples always forget: sales tax, an 18–22% service charge on the venue side, and bartender gratuity. Our tax & tip calculator stacks all three so your quote comparison is apples to apples, and the wedding vendor tipping guide covers what to hand your bar staff at the end of the night.

Storage, Returns & Day-Of Setup

Three habits protect the money you've already spent:

• Keep everything returnable as long as possible. Store wine and spirits at room temperature, upright and out of sunlight. Don't chill a case just because the fridge has room — chilled bottles can't go back.
• Keep every receipt in one envelope. Tape it inside a folder, photograph the totals, and note which store each case came from. Returns without a receipt usually fail.
• Chill in waves. Load one cooler per drink category in the order guests will drink them: cocktails and white wine first, beer through the night, sparkling last, right before the toast.

On setup day, build the bar backwards from the guests' arrival: ice and bottles staged, garnish tray assembled, mocktail station right next to the bar (not across the room), and a dedicated water table. Guests who find water first drink less alcohol, which is why so many couples finish the night with returnable cases instead of an empty one.

Build Your Exact List in 30 Seconds

Your crowd is not the average crowd. A Sunday brunch and a Saturday night dance party can differ by 150 drinks at the same headcount. Adjust the drinker percentage, reception length, and drink split, and get your own bottle counts, case counts and cost estimate — then carry the list straight into the store.
