# How Much Alcohol for a Wedding: A 2026 Calculator and Planning Guide

> One drink per guest per hour is the rule, but the real calculation is more nuanced — this guide walks you through the math for every guest count, bar type, and reception length so you never run short or over-order.

*Published 2026-06-24 · By Grace Bellamy*

In short
The professional rule is one drink per guest per hour, with a refinement: plan for two drinks in hour one (cocktail hour drinks fastest) and one drink per hour thereafter. For a five-hour reception with 100 guests, that is roughly 500–600 total drinks. Always buy 10–15% more than your estimate and shop at a retailer with an unopened-bottle return policy.

Running out of wine at a wedding reception is the single most memorable hospitality failure guests will discuss for years afterward — and it is entirely preventable with one afternoon of honest math. Yet the reverse — over-ordering by so much that two cases of wine go to waste — is nearly as common, and considerably more expensive. The goal of this guide is to help you order precisely: enough to ensure generosity, not so much that you are donating to your caterer's pantry.

The calculations below are grounded in the industry-standard formula used by professional bartenders and validated by resources including [Joy's wedding alcohol calculator](https://withjoy.com/blog/wedding-alcohol-calculator/) and The Knot's bar planning guidance. Adjust up or down based on the specific character of your guest list — an older, largely non-drinking crowd needs less; a younger group of social dancers needs more.

## What is the standard formula for calculating wedding alcohol?

The baseline: **one drink per guest per hour**. But professional bartenders refine this further:

- **Hour one (cocktail hour):** plan for 2 drinks per drinking guest

- **Each subsequent hour:** plan for 1 drink per drinking guest

For a 5-hour reception (1-hour cocktail hour + 4-hour dinner and dancing), that equals approximately 6 drinks per guest who drinks. Remember that roughly 15–20% of your guests typically do not drink alcohol — subtract those guests from your alcohol calculation and ensure you have robust non-alcoholic options for them.

The [Reventals party drink calculator](https://www.reventals.com/blog/party-drink-calculator-how-much-alcohol/) notes that as of 2026, average national pricing runs approximately $1.33 per beer, $13 per bottle of wine, and $28 per bottle of spirits (well brands). At these prices, a self-catered open bar for 100 guests at a 5-hour reception runs $800–$1,800 for alcohol alone before mixers, ice, and bartender labor.

## How do you divide the alcohol between beer, wine, and spirits?

  Wedding Alcohol Split Guide: Drinks by Type and Guest Preference

      Drink Type
      Typical Share
      Bottle Yield
      Notes

      Wine (red + white + rosé)
      35–40% of consumption
      5 glasses per 750ml bottle
      Rosé is no longer seasonal — include year-round; roughly 40% red, 40% white, 20% rosé

      Beer
      30–35% of consumption
      1 serving per 12 oz bottle or can
      Offer both a lager/light beer and a craft option; kegs (½ barrel = 165 servings) for 150+ guests

      Spirits / mixed drinks
      25–30% of consumption
      17 drinks per 750ml bottle (1.5 oz pour)
      Vodka is the highest-volume spirit at most American weddings; follow with bourbon, gin, rum, tequila in that order

      Champagne / Prosecco (toast)
      Toast only (single pour)
      4–5 flutes per 750ml bottle
      1 bottle per 4–5 guests; Prosecco or Cava are excellent substitutes at half the price

      Non-alcoholic options
      15–20% of guests
      Varies
      Budget 3 non-alcoholic drinks per non-drinking guest; include at least one interesting mocktail or sparkling option

## What are the specific bottle counts for different guest counts?

The following quantities are calculated for a 5-hour reception (1 cocktail hour + 4 hours dinner and dancing) with approximately 80% of guests drinking. Adjust proportionally for different reception lengths or drinking cultures. All quantities include a 10% buffer above the calculated need.

**50-guest wedding (5 hours):**

- Wine (red): 7–8 bottles | Wine (white): 6–7 bottles | Wine (rosé): 4–5 bottles

- Champagne for toast: 10–13 bottles

- Beer (assorted): 4–5 cases (96–120 units)

- Vodka: 2 liters | Bourbon/whiskey: 1.5 liters | Gin: 1 liter | Rum: 1 liter | Tequila: 1 liter

- Ice: 50–75 lbs

**100-guest wedding (5 hours):**

- Wine (red): 12–15 bottles | Wine (white): 10–12 bottles | Wine (rosé): 6–8 bottles

- Champagne for toast: 20–25 bottles

- Beer (assorted): 8–10 cases (192–240 units)

- Vodka: 3–4 liters | Bourbon/whiskey: 2–3 liters | Gin: 1–2 liters | Rum: 1–2 liters | Tequila: 1–2 liters

- Ice: 100–150 lbs

**150-guest wedding (5 hours):**

- Wine (red): 18–22 bottles | Wine (white): 15–18 bottles | Wine (rosé): 9–12 bottles

- Champagne for toast: 30–38 bottles

- Beer (assorted): 12–15 cases (288–360 units)

- Vodka: 4–5 liters | Bourbon/whiskey: 3–4 liters | Gin: 2 liters | Rum: 2 liters | Tequila: 2 liters

- Ice: 150–200 lbs

**200-guest wedding (5 hours):**

- Wine (red): 24–28 bottles | Wine (white): 20–24 bottles | Wine (rosé): 12–15 bottles

- Champagne for toast: 40–50 bottles

- Beer (assorted): 16–20 cases (384–480 units); consider a ½-barrel keg for the primary lager

- Vodka: 5–6 liters | Bourbon/whiskey: 4 liters | Gin: 2–3 liters | Rum: 2–3 liters | Tequila: 2–3 liters

- Ice: 200–300 lbs

## What else should you budget beyond the alcohol itself?

The alcohol cost is only part of the bar budget. A complete bar budget must include bartender labor ($25–$60 per hour per bartender; industry standard is one bartender per 50–75 guests), mixers and garnishes ($3–$8 per guest), glassware rental ($1–$3 per glass if not provided by the venue), ice, and any corkage fees your venue charges for outside alcohol (typically $5–$25 per bottle or $5–$15 per guest). According to [Zola's bar planning guide](https://www.zola.com/expert-advice/how-to-calculate-alcohol-needs-for-your-wedding), total bar and beverage service — including all components — represents approximately 10–15% of total wedding spend, with the national average running $2,800–$5,500 depending on guest count, location, and bar type.

The smart purchasing strategy for self-catered bars: buy from Total Wine, Costco, or another warehouse retailer that accepts returns on unopened bottles. Purchase 10–15% above your calculated need, keep all receipts, and return whatever remains. This eliminates the risk of running short without wasting money on over-purchasing.
