For a 5-hour reception with moderate drinkers: 9 cases of beer (216 bottles), 40 bottles of wine, and 6 bottles of liquor. This provides 500 total drinks (5 per guest). Light drinkers need 25% less, heavy drinkers 25% more. Always buy 10% extra to avoid running out.

What is the best alcohol ratio for a wedding?

Typical ratio is 40% beer, 40% wine, 20% liquor for mixed crowds. Summer weddings: increase beer to 50%. Formal/dinner weddings: increase wine to 50%. Younger crowds (21-30): increase liquor to 30%. Older crowds (50+): 30% beer, 60% wine, 10% liquor. Poll guests beforehand for accurate preferences.

How many drinks per person at a wedding?

Plan for 1 drink per hour per guest for cocktail hour + reception. Light drinkers: 3-4 drinks total. Average: 5-6 drinks. Party crowd: 7-8 drinks. First hour (cocktail): 1.5 drinks/person. Dinner hour: 0.5 drinks/person. Dancing hours: 1.5 drinks/person/hour. Many guests won't drink - others will drink more.

Should I have an open or cash bar at my wedding?

Open bar is standard etiquette and expected at most weddings ($15-30/person). Cash bar saves money but may upset guests who traveled far. Limited bar (beer/wine only): $10-15/person, good compromise. Drink tickets (2-3 free, then cash): balances cost and hospitality. Budget $1,500-3,000 for open bar for 100 guests.
