How the Estimate Works
1. Count Active Drinkers
Enter the guest list and exclude the percentage who will not drink alcohol.
2. Set Party Duration
The model reserves 2 servings in hour one and 1 in each later hour.
3. Round to Packages
The selected profile becomes beer cases, wine bottles, and liquor bottles.
Cocktail Party Quick Reference
Three-hour Cocktail Crowd inventory with no assumed non-drinkers or buffer
| Guests | Base servings | Beer | Wine bottles | Liquor bottles |
|---|---|---|---|---|
| 25 | 100 | 20 beers (1 cases) | 4 | 4 |
| 50 | 200 | 40 beers (2 cases) | 8 | 8 |
| 75 | 300 | 60 beers (3 cases) | 12 | 11 |
| 100 | 400 | 80 beers (4 cases) | 16 | 15 |
Category and package rounding can create more packaged capacity than the base serving estimate. Recipe ingredients, mixers, garnishes, and ice are not included.

Frequently Asked Questions
How much alcohol do I need for a cocktail party of 30 guests?
For 30 guests, 3 hours, no assumed non-drinkers, a Cocktail Crowd profile, and no buffer, the calculator reserves 120 servings: 24 beers (1 case), 5 wine bottles, and 5 liquor bottles. This is an inventory estimate, not a recommendation for how much guests should consume.
What does the default cocktail party example produce?
The default is 50 guests for 3 hours, with no assumed non-drinkers, a 20% beer, 20% wine, and 60% liquor Cocktail Crowd split, and the optional buffer switched off. It produces 200 base inventory servings, packaged as 2 beer cases, 8 wine bottles, and 8 liquor bottles.
How does the cocktail party calculator work?
It reserves 2 servings per active drinking guest for the first hour and 1 for each later hour. It applies the chosen drink mix, rounds each category up, and converts it using 24 beers per case, 5 wine servings per bottle, and 17 liquor servings per 750ml bottle.
Does one liquor bottle always make 17 finished cocktails?
No. The calculator conversion is based on 17 standard 1.5oz liquor servings from a 750ml bottle. A finished cocktail may use a different pour or more than one spirit, so scale every recipe from its measured ingredients and stated yield.
Are mixers, garnishes, and ice included?
No. Results cover packaged beer, wine, and liquor only. Choose the cocktail menu first, then calculate mixers and garnishes from each recipe yield. Confirm ice needs with your bartender, caterer, or venue because service style and storage change the amount.
How should I budget for a cocktail party?
Price the calculated packages with current local quotes, then add the exact recipes, ice, alcohol-free drinks, service, delivery, tax, and venue fees that apply to your event. Product choices and local prices vary too much for one universal party budget.
