# Wedding Alcohol Calculator Calculate how much beer, wine, and liquor to buy for your wedding. Enter guest count, event hours, and drinking preferences for an accurate estimate. ## What this calculates Figuring out how much alcohol to buy for a wedding is one of those tasks that feels like guesswork. This calculator takes the uncertainty out of it by estimating beer, wine, and liquor quantities based on your guest count, event duration, and crowd preferences. ## Inputs - **Number of Guests** — min 10, max 1000 - **Event Duration** (hours) — min 1, max 12 — Duration of the cocktail hour + reception - **Guest Drinking Level** — options: Light (brunch, daytime, many non-drinkers), Average (typical wedding crowd), Heavy (late night, party crowd) - **Non-Drinkers** (%) — min 0, max 100 — Estimated percentage of guests who will not drink alcohol - **Beer Drinkers** (%) — min 0, max 100 — Percentage of drinkers who prefer beer - **Wine Drinkers** (%) — min 0, max 100 — Percentage of drinkers who prefer wine - **Liquor/Cocktail Drinkers** (%) — min 0, max 100 — Percentage of drinkers who prefer cocktails or spirits ## Outputs - **Total Drinks Needed** — Estimated total standard drinks for the event - **Beer** — formatted as text — Number of 12 oz bottles/cans needed - **Wine** — formatted as text — Number of 750 mL bottles needed - **Liquor** — formatted as text — Number of 750 mL bottles needed - **Champagne (Toast)** — formatted as text — Bottles for a single toast (if desired) - **Budget Tip** — formatted as text — Cost-saving advice based on your event size ## Details The standard industry rule of thumb is **one drink per guest per hour**, but that is just an average. The first hour (usually cocktail hour) tends to be heavier, and consumption drops off as the night goes on. This calculator adjusts for that pattern. **What counts as one drink:** - 1 beer (12 oz) - 1 glass of wine (5 oz) - 1 cocktail (1.5 oz of liquor) **Bottles math:** - 1 wine bottle (750 mL) = 5 glasses - 1 liquor bottle (750 mL) = about 17 standard cocktails - 1 champagne bottle = 6 flutes - 1 beer case = 24 bottles/cans **Tips for getting the quantities right:** 1. **Adjust for your crowd.** A Sunday brunch wedding will drink less than a Saturday night barn party. Older guests tend to drink less than younger crowds. If many guests are family with kids, bump up the non-drinker percentage. 2. **Seasonal adjustments.** Summer weddings tend to see more beer consumption. Winter weddings skew toward wine and cocktails. 3. **The toast.** Champagne toasts are traditional but not required. If you include one, plan for one flute per guest (even non-drinkers often participate). You can skip this entirely if budget is tight. 4. **Buffer stock.** This calculator adds a 10% buffer to all quantities. Better to have a few extra bottles than to run out at 9 PM. 5. **Return policies.** Many liquor stores allow returns on unopened, undamaged bottles purchased for events. Ask before you buy and keep your receipt. 6. **Hire a bartender.** Professional bartenders control pour sizes, which actually saves alcohol. Self-serve bars burn through liquor much faster. ## Frequently Asked Questions **Q: How much alcohol do I need for 100 guests?** A: For a 5-hour reception with 100 guests (20% non-drinkers, average drinking level), you would need roughly 400 total drinks. With a typical 30/40/30 split of beer/wine/liquor, that works out to approximately 132 beers (6 cases), 18 wine bottles, and 8 liquor bottles. Add champagne for a toast and you need about 17 bottles. These numbers include a 10% buffer. **Q: Should I offer a full bar or just beer and wine?** A: Both are perfectly acceptable. Beer and wine only is simpler, cheaper, and easier to manage. A full bar with cocktails adds variety but increases cost and complexity (you need mixers, garnishes, and ideally a bartender). A popular middle ground is offering a signature cocktail alongside beer and wine, which adds personality without a full bar setup. **Q: How much does wedding alcohol typically cost?** A: Costs vary hugely by region and taste. For a 150-guest wedding with a full bar, budget roughly $10-$20 per guest for mid-range options from a liquor store ($1,500-$3,000 total). Venue-provided bars with per-drink pricing typically run $35-$75 per person. Buying your own alcohol (if the venue allows it) is almost always cheaper. The biggest cost factors are top-shelf vs. well liquor and how heavy your crowd drinks. **Q: What mixers and supplies do I need?** A: For a basic bar: tonic water, club soda, cola, diet cola, ginger ale, cranberry juice, orange juice, and lemon/lime wedges. Plan about 1 liter of mixers per 3 guests. You also need ice (1.5 lbs per guest, more in summer), cups or glassware, napkins, a bottle opener, and a corkscrew. For cocktails, add whatever the recipes require. Do not forget non-alcoholic options: water, iced tea, lemonade, and ideally a mocktail option. --- Source: https://vastcalc.com/calculators/health/wedding-alcohol Category: Health & Fitness Last updated: 2026-04-08
