Complete Reception Beverage & Ice Calculations

A comprehensive wedding bar requires calculating not just alcoholic beverages, but also non-alcoholic mocktails, sodas, spring water, and bulk ice poundage for chilling and serving.

The 1.5 lb Ice Rule

Catering standards recommend 1.5 lbs of ice per guest for indoor receptions (and 2.0 to 2.5 lbs per guest for outdoor summer weddings) to cover both glassware ice and bottle chilling tubs.

Non-Alcoholic Pacing Ratio

Plan for 2 non-alcoholic drinks per drinking guest (water/soda between cocktails) plus 1 soft drink per hour for designated drivers and non-drinking attendees.
