How to Use Wedding Alcohol Calculator
The Wedding Alcohol Calculator turns a few simple inputs into a complete wedding bar plan.
- Enter guest count and event length — Drinking time is the biggest driver. Cocktail hour + dinner + dancing usually totals 4–6 hours.
- Pick drinking style — Choose Light, Moderate or Heavy. The Wedding Alcohol Calculator uses 0.75 / 1.0 / 1.75 drinks per hour respectively.
- Choose the alcohol mix — Beer only, wine only, beer + wine, the full bar, or a champagne toast.
- Adjust share percentages and buffer — Fine tune beer / wine / liquor splits and how much safety stock to keep.
- Read the plan — The Wedding Alcohol Calculator returns total drinks, beer bottles, wine bottles (750 ml), champagne bottles and liquor bottles.
Formula & Theory — Wedding Alcohol Calculator
The Wedding Alcohol Calculator is based on standard catering rules.
drinkers = guests × drinking_percentage
total = drinkers × hours × drinks_per_hour
beer = total × beer_share
wine = total × wine_share
liquor = total × liquor_share
bottles_w = ceil(wine_drinks / 5 × buffer) # 5 glasses per 750 ml
bottles_l = ceil(liquor_drinks / 16 × buffer) # 16 shots per 750 ml
champagne = ceil(guests / 6 × buffer) # 1 bottle per 6 guests| Symbol | Meaning |
|---|---|
| drinkers | Drinking adults attending the wedding |
| drinks_per_hour | 0.75 / 1.0 / 1.75 by drinking level |
| buffer | 1 + safety reserve % |
