How Many Kegs for a 150-Person Wedding? (Simple Math)
Planning a wedding with a non-alcoholic option on tap? Here's the simple formula to figure out exactly how many kegs you need.
The Formula
Wedding beverage planning doesn't have to be complicated. Here's the math:
Guests × Drinks per Guest × NA Percentage = Total NA Drinks Needed
Then divide by pours per keg.
Let's Run the Numbers for 150 Guests
Assumptions
- Event duration: 5 hours
- Drinks per guest: 4-5 over the evening
- Percentage choosing NA: 15-25% (industry average is climbing)
Conservative Estimate (15% NA)
- 150 guests × 4.5 drinks × 15% = ~101 NA drinks
- That's roughly 2 sixtels or 1 quarter barrel + 1 sixtel
Higher Estimate (25% NA)
- 150 guests × 4.5 drinks × 25% = ~169 NA drinks
- That's roughly 1 half barrel or 2 quarter barrels
What We Recommend
For a 150-person wedding, order 1 half barrel. Here's why:
1. Buffer: You'd rather have leftover than run out
2. Variety: Many couples order 2 sixtels of different flavors instead of 1 half barrel - guests love choosing
3. Cost: A half barrel is more cost-effective per pour than two sixtels
Flavor Pairing Ideas for Weddings
- Classic combo: One hoppy NA IPA + one crisp NA lager
- Sophisticated: NA sparkling rosé + NA craft pilsner
- Summer: NA ginger beer + NA pale ale
Logistics Checklist
- Confirm venue has space for a jockey box or kegerator
- Order kegs 2 weeks before the event
- PourZero delivers the tap equipment - no rental needed
- Designate a "tap tender" (or we can recommend one)
