Wedding Alcohol Calculator 2026 – Spirits, Wine & Beer

FAQ

How much alcohol do I need per wedding guest?

A standard 5–6 hour reception with moderate drinking averages 5–7 drinks per guest total across wine, beer, and spirits.

Party Style	Drinks Per Guest (5 hrs)	Drinks Per Guest (6 hrs)
Light / family crowd	3 – 4	4 – 5
Moderate / typical wedding	5 – 6	6 – 7
Lively / party crowd	7 – 9	8 – 10

Add +15% for every 2 extra hours beyond 6 hours of open bar.

How many bottles of wine, beer, and spirits for 100 guests?

Use these moderate-party benchmarks for a 6-hour reception (before buffer).

Beverage	Bottles for 100 Guests	Serving Notes
Wine (total)	50 – 60 bottles	~5 glasses per bottle
White wine (60% split)	30 – 36 bottles	Popular year-round
Red wine (40% split)	20 – 24 bottles	Heavier in fall/winter
Sparkling (toast)	15 – 20 bottles	1 glass per guest
Beer	200 – 300 bottles	2 – 3 per guest
Spirits (mixed)	10 – 12 bottles	1 bottle per 8–10 guests

Always add 15–20% extra and keep receipts for unopened returns.

How does party style change bottle quantities?

Your crowd's drinking habits matter more than formulas alone. Adjust the calculator accordingly.

Party Style	Wine Multiplier	Beer Multiplier	Spirits Multiplier
Light / daytime brunch	×0.7	×0.6	×0.5
Moderate / standard	×1.0	×1.0	×1.0
Lively / late-night dance party	×1.4	×1.4	×1.5

A lively 100-guest party may need 70+ wine bottles and 400+ beers vs. 50 wine and 200 beer for a light crowd.

How much does a wedding bar cost in 2026?

DIY bar costs vs. venue open-bar packages differ significantly. Budget both liquor and mixers.

Bar Option	Cost for 100 Guests (2026 USD)	Pros / Cons
DIY beer + wine only	$1,500 – $3,000	Affordable; limited selection
DIY full bar (buy own liquor)	$2,500 – $5,000	Best value if venue allows
Venue open bar (standard)	$4,000 – $8,000	Convenient; per-person pricing
Venue open bar (premium spirits)	$8,000 – $15,000	Top-shelf; highest cost
Cash bar (guests pay)	$500 – $1,500 setup	Controversial; saves host money

Per-person open bar pricing typically runs $25 – $60/guest for 4–5 hours in 2026.

What non-alcoholic drinks and mixers should I budget?

A complete bar includes mixers, water, and alcohol-free options — often overlooked in bottle counts.

Item	Quantity (100 guests)	Cost (2026 USD)
Soft drinks / mixers (2L)	35 – 45 bottles	$70 – $120
Tonic, soda water, ginger beer	20 – 30 liters	$40 – $80
Still + sparkling water	40 – 60 bottles	$50 – $100
Juice (cranberry, orange)	10 – 15 liters	$30 – $50
Coffee + tea service	1 station	$200 – $400
Non-alcoholic beer / mocktails	5–10% of beer count	$80 – $150

Buy from retailers that accept unopened case returns — Costco, Total Wine, and many local liquor stores offer this in 2026.
