Why This Guide Exists
Planning the drink side of an event can be confusing — how much alcohol should you buy, how much ice do you need, how many cups are enough, and what happens if your venue has rules like no shots, no glass outdoors, or no self-serve alcohol?
This guide gives you real-world bartender formulas so you can confidently plan your event bar — even if you are not hiring a bartending service.
Step 1: Lock In Your Event Details
Before buying anything, confirm:
• Final guest count
• Total bar service hours
• Indoor, outdoor, or mixed location
• Type of crowd (light, moderate, heavy drinkers)
• Venue alcohol rules
These details control every calculation in this guide.
Step 2: Estimate Total Drinks Needed
Use this industry-standard formula:
Light drinking → 1 drink per guest per hour
Moderate drinking → 1.5 drinks per guest per hour
Heavy drinking → 2 drinks per guest per hour
Formula:
Guest Count × Hours × Drinking Level = Total Drinks Needed
Step 3: Choose Your Drink Split (Modern Event Crowd)
Modern events are cocktail-heavy. Use these realistic planning ranges:
• Cocktails: 50–70% of total drinks
• Beer: 20–50% of total drinks
• Wine: 10–15% of total drinks
Choose where your crowd fits within these ranges based on age, season, and venue rules.
Step 4: Convert Drinks Into Bottles
Beer
1 drink = 1 bottle or can
Wine
750ml bottle ≈ 5 glasses
Cocktails (2 oz pours)
Each cocktail uses about 2 oz of liquor
1 bottle (750ml) ≈ 12 cocktails
Step 5: Ice Planning (Critical)
Ice is the most underestimated part of event bars.
General Rule of Thumb
Plan approximately 2 pounds of ice per guest for up to 5 hours of bar service.
This safely covers:
• Ice for chilling drinks
• Ice used in cocktails
• Normal melting and handling loss
Increase Ice By 15–30% If Your Event Is:
• Outdoors
• During warm or hot weather
• Cocktail-heavy
• Longer than 5 hours
Always round ice up — running out of ice is one of the biggest event mistakes.
Step 6: Cups
Choose one method:
• Simple method → Guests × 2
• Detailed method → Total drinks × 1.1
Round up for cocktail-heavy events.
Step 7: When to Buy & Chill
Alcohol
• Purchase 2–3 days before your event
• Chill beer and wine 24–48 hours before
Ice
• Buy the morning of your event
• Store in insulated coolers
Step 8: Bar Setup Best Practices
• Keep ice behind the bar
• Place trash bins near the bar
• Separate kid-friendly drinks
• Pre-cut garnishes
• Keep backup ice accessible
Step 9: Common Venue Rules
• No shots or doubles
• No self-serve alcohol
• No glass outdoors
• Valid ID required
Always confirm with your venue.
