Service Plan for 125 Guests
For a event, plan on approximately 375 total servings over a 4-hour event. Keep a 15-20% buffer so you can handle late arrivals and heavier-than-average consumption.
Because beer is typically served alongside other drinks, set a second non-alcoholic option to avoid over-concentration on a single beverage and reduce stockout risk.
- Prep checklist: 450+ cups, 188+ lbs of ice, and backup storage nearby.
- Chill strategy: pre-chill at least 70% before service to reduce ice melt and dilution.
- Replenishment cadence: refresh serving stations every 30-45 minutes instead of all at once.
