Frequently Asked Questions

How much alcohol do I need for a party of 50?

For a 4-hour party with 50 guests, plan for about 200 drinks total. Using a standard mix, that is roughly 80 beers (7 cases), 15 bottles of wine, and enough liquor for 48 cocktails (2-3 bottles). Use our calculator for exact quantities based on your crowd.

How many bottles of wine for 30 people?

For 30 people at a 4-hour party where wine is served alongside beer and cocktails, plan for about 10-12 bottles of wine. If your crowd skews toward wine lovers, increase to 15-18 bottles. The standard rule is about 1 bottle per 2.5 wine-drinking guests per hour.

How many cases of beer for a house party?

For a typical 4-hour house party, plan 1 case (24 beers) per 6-8 guests. A 30-person party needs about 4-5 cases, and a 50-person party needs 7-8 cases. If your crowd leans heavily toward beer, add 1-2 extra cases. Our calculator adjusts for your specific crowd profile.

What is the rule of thumb for how many drinks per person at a party?

The standard rule is 1 drink per guest per hour. Some planners use 2 drinks for the first hour, then 1 per hour after. For a 4-hour party, plan 4-5 drinks per person to be safe.

How much ice do I need for a party of 50?

Plan for 1.5 pounds of ice per guest. For a 50-person party, that is about 75 pounds. Double this if you are chilling bottles in tubs rather than a refrigerator.
