Frequently Asked Questions

Q

How many drinks should I plan per person at a party?

Plan for 1 to 2 drinks in the first hour and about 1 drink per hour after that for moderate drinkers. A 4-hour party with moderate drinkers averages about 6 drinks per guest. Light drinkers average 1 per hour and heavy drinkers average 2 per hour.

  • Light drinkers: 1 drink/hour — a 4-hour party = 4 drinks per person
  • Moderate drinkers: 1.5 drinks/hour — a 4-hour party = 6 drinks per person
  • Heavy drinkers: 2 drinks/hour — a 4-hour party = 8 drinks per person
  • Assume 10–15% of guests will not drink alcohol — always stock non-alcoholic options
  • Brunch and afternoon events trend lighter (1/hr); evening parties and celebrations trend heavier (1.5–2/hr)
Q

How much ice do I need for a party?

Plan for about 1 pound of ice per person. Buy 10-pound bags and figure one bag for every 10 guests. If it is a hot outdoor party or you are chilling beer in coolers, double the ice. Keep extra bags in a cooler or freezer as backup.

  • 1 lb/person for indoor parties; 2 lbs/person for outdoor summer events above 80°F
  • A standard cooler holds 40 lbs of ice plus 24–36 cans — plan cooler capacity accordingly
  • Buy ice the morning of the party and store unopened bags in a chest freezer until 1 hour before guests arrive
  • Use separate ice for drinks (clean) vs chilling bottles/cans (can use lower-quality bagged ice)
  • A 50-guest outdoor party needs roughly 100 lbs of ice — ten 10-lb bags ($20–30 total)
Q

What is a good beer-wine-cocktail ratio for a party?

A popular default split is 40% beer, 30% wine, 20% cocktails, and 10% non-alcoholic drinks. Adjust based on your crowd: younger guests skew toward beer and cocktails, dinner parties skew toward wine, and always keep non-alcoholic options available.

  • Casual BBQ/sports party: 50% beer, 20% wine, 20% cocktails, 10% non-alcoholic
  • Dinner party: 20% beer, 50% wine, 20% cocktails, 10% non-alcoholic
  • Wedding reception: 30% beer, 40% wine, 25% cocktails, 5% non-alcoholic
  • Stock 2–3 beer varieties (light, IPA, domestic), 1 red and 1 white wine, and 1–2 cocktail options
  • Non-alcoholic options are trending — budget 10–15% of total drinks for sparkling water, mocktails, and soda

Q

How many glasses of wine come from one bottle?

A standard 750ml wine bottle yields about 5 glasses at 5 oz each. For a party of 30 moderate drinkers over 4 hours where 30% of drinks are wine, you would need about 11 bottles. Buy a mix of red and white, and consider sparkling wine if you plan toasts.

  • A 750ml bottle = 25.4 oz = 5 glasses at a 5 oz pour (standard serving size)
  • A magnum (1.5L) yields 10 glasses and is more cost-effective for parties at $15–25 per bottle
  • For 50 guests with 30% wine drinkers over 4 hours: ~18 bottles needed (90 wine drinks ÷ 5 per bottle)
  • Buy 60% white/rosé and 40% red for warm-weather parties; reverse the ratio for fall/winter events
  • Chill white wine 2 hours before the party and open red 30 minutes early to let it breathe

With 30 guests drinking moderately over 4 hours, each person averages 6 drinks (1.5 in the first hour, 1.5/hr after). That gives 180 total drinks split into 72 beers (3 cases), 54 glasses of wine (11 bottles), 36 cocktails (3 spirit bottles + 3 mixer bottles), and 18 non-alcoholic drinks (3 soda bottles), plus 3 bags of ice.

A 100-guest wedding over 5 hours at moderate pace yields 7.5 drinks per person (750 total). With a wine-heavy mix typical of weddings: 225 beers (10 cases), 300 wine glasses (60 bottles), 187 cocktails (12 spirit bottles + 12 mixer bottles), and 38 non-alcoholic drinks (5 soda bottles), plus 10 bags of ice.

Formulas Used

Drinks Per Person

D = min(2, R) + max(0, H - 1) × R

Calculates total drinks per person based on hourly rate with a first-hour cap of 2

Where:

D= Total drinks per person
R= Hourly drinking rate (1.0 light, 1.5 moderate, 2.0 heavy)
H= Party duration in hours

Category Quantities

Beer cases = ⌈(Total × Beer% / 100) / 24⌉, Wine bottles = ⌈(Total × Wine% / 100) / 5⌉

Converts total drink count into purchasable units (cases of 24, bottles of 5 servings)

Where:

Total= Guests × drinks per person
Beer%= Percentage allocated to beer
Wine%= Percentage allocated to wine

How to Calculate Drinks for Any Party

Planning the right amount of drinks is one of the most stressful parts of hosting a party. Buy too little and you run out early. Buy too much and you are stuck with cases of warm beer. The key is a simple formula: estimate drinks per person based on your party length and drinking pace, then split that total across beer, wine, cocktails, and non-alcoholic beverages.

Most bartenders use the rule of one drink for the first hour and one drink per hour after that for average drinkers. Our calculator refines this by letting you set the actual pace (light, moderate, or heavy) and adjusting the first-hour cap. It then converts total drinks into real shopping quantities: cases of 24 beers, 750ml wine bottles (5 glasses each), spirit bottles (about 17 cocktails per 750ml), and 2-liter mixer and soda bottles.

Do not forget the ice. One pound per guest is the baseline, but outdoor summer parties need double. Buy 10-pound bags and keep extras in a freezer. Finally, always round up when buying. Leftover sealed beer and wine keep for months, but running out mid-party is a hosting nightmare nobody forgets.
