- ✓ Label clearly as alcoholic
- ✓ Provide a ladle for self-service
Service Plan for 20 Guests
For a medium party, plan on approximately 40 total servings over a 3-hour event. Keep a 10-15% buffer so you can handle late arrivals and heavier-than-average consumption.
Because party punch (alcoholic) 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: 48+ cups, 30+ 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.
