One of the most common questions couples ask during wedding planning is:
“How much alcohol should we purchase for our wedding?”
Between beer, wine, liquor, signature cocktails, and non-alcoholic beverages, planning your wedding bar can quickly feel overwhelming. Purchase too little, and you risk running out during the reception. Purchase too much, and you may spend hundreds (or thousands) more than necessary and have a surplus of alcohol and non-alcoholic beverages leftover to take home.
As wedding venue owners and coordinators, we’ve hosted hundreds of weddings of all sizes and styles, and we’ve seen firsthand what works best when it comes to building a successful wedding bar.
This guide will help you determine:
- Which wedding bar beverages to offer
- How much alcohol to buy for your wedding
- How guest count and wedding style affect consumption
- Tips to stay on budget while keeping guests happy
Start With Your Wedding Style and Guest Experience
Before calculating quantities, think about the atmosphere you want to create.
Ask yourself:
- Is this a formal evening wedding or casual celebration?
- Do we want to offer a full open bar or limited selections?
- Are our guests primarily beer drinkers, wine drinkers, or cocktail drinkers?
- Will our reception be during the afternoon or evening?
- How long is our reception?
These factors significantly impact alcohol consumption.
General Guidelines:
- Evening weddings typically consume more alcohol than daytime weddings.
- Longer receptions require more beverages.
- Summer weddings often increase beer and light cocktail consumption.
- Formal weddings tend to see higher wine and cocktail service.

How Much Alcohol to Buy for a Wedding
One of the most searched wedding planning questions online is:
“How many drinks should I plan per guest?”
Standard Wedding Alcohol Calculator Rule:
For average drinkers plan for:
- 1 drink per guest during the first hour
- 1 additional drink every hour afterward
Example Wedding Alcohol Calculation
150 Guests
5-Hour Reception
Calculation:
150 guests × 5 drinks = 750 total drinks
Wedding Alcohol Breakdown Guide
Beer
Estimate:
30% of total drinks
Formula:
Total drinks × 0.3
Example:
750 × 0.3 = 225 – 12 oz. beers
Best Beer Choices:
Offer:
- 1 light beer
- 1 domestic beer
- 1 craft or local beer/seltzer option
Wine
Estimate:
- 20% of total drinks
Example:
750 × 0.2 = 150 glasses of wine
Important Guideline:
One standard 750 mL wine bottle provides approximately:
- 4 glasses of wine
Example:
150 wine servings ÷ 4 = approximately 36 – 750 mL bottles (approximately 18 – 1.5 L bottles)
Suggested Wine Mix:
- 40% white wine
- 40% red wine
- 20% rosé, sweet, or sparkling
Liquor
Estimate:
- 50% of total drinks
Example:
750 × 0.5 = 375 – 1.5 oz pours of liquor
Typical Wedding Bar Liquor:
- Vodka
- Bourbon/whiskey
- Tequila
- Gin
- Spiced/Clear Rum
- Malibu
Bottle Planning:
A standard 750 mL liquor bottle provides approximately:
- 17 mixed drinks
Example:
375 cocktails ÷ 17 = approximately 22 – 750 mL bottles (approximately 11 – 1.75 L handles)
Don’t Forget Non-Alcoholic Drinks
For your convenience, Melhorn Manor offers a bottomless non-alcoholic drink/mixer package which allows you to relax and enjoy your wedding day without worrying if the non-alcoholic drinks will run out before the reception ends. No one wants to ask a family member or friend to leave the reception to purchase more soda or juice if the bar runs out of non-alcoholic beverage(s) supplied by the couple but the correct amount was not purchased.
Every wedding should offer:
- Water
- Soft drinks
- Tea/lemonade
Some guests:
- don’t drink alcohol
- are pregnant
- are designated drivers
- appreciate non-alcoholic alternatives
Wedding Bar Budget Tips
1. Limit the Liquor Selection
You do not need every spirit.
Most wedding guests primarily order:
- vodka
- bourbon/whiskey
- rum
A focused menu saves money.
2. Offer Signature Cocktails
Signature drinks:
- reduces inventory complexity
- speeds up service
- reduces waste
Popular options:
- Old Fashioned
- Margarita
- Moscow Mule
- Orange Crush
- Malibu Baybreeze
3. Buy From Stores With Return Policies
Some retailers allow returns on unopened alcohol.
Always verify local laws and store policies before purchasing alcohol.
4. Avoid Overstocking Champagne
Champagne is often overpurchased for wedding toasts. Melhorn staff usually fills champagne flutes about half full for toasts. We can fill about 8-10 champagne flutes with one 750 mL bottle of champagne.
Reality:
Most guests only consume:
- one partial glass during the toast
Common Wedding Alcohol Mistakes
Offering Too Many Options
Too much variety:
- increases cost
- slows bar service
- creates waste
Simple bars often perform best.
Ice Needs
Rule of thumb:
- 1 – 1.5 pounds of ice per guest
Luckily Melhorn Manor Bar Service, and our Exclusive Caterers who offer bar service, provide all ice needed for your wedding day so you can rest assured you will not need to purchase and you will run out of ice!
Forgetting Water Stations
Hydration is essential, especially for summer weddings, when alcohol is being served and outdoor venues. Melhorn Manor always ensures there is a water station available at every wedding during the cocktail hour and reception.
