How much should
you buy?

The mix is 40% cocktails, 35% wine, and 25% beer; wine-and-beer mode uses 60% wine and 40% beer. A 750 mL spirits bottle yields about 16 single-spirit drinks at 1.5 oz, and a wine bottle yields five 5 oz glasses. Mixers assume 4 oz per cocktail, citrus assumes about ten garnish portions per fruit, and cups include a 20% buffer. Water, ice, and serving supplies are adjustable planning allowances. Additional ingredients depend on the recipes.

Hours set a suggested drink estimate; you can edit the total per guest. Outdoor mode raises the ice allowance, which you can also adjust.
