How Much Beer for a Wedding?

The Wedding Beer Formula

The Standard Crowd planning profile assigns 33% of the bar inventory to beer. For a 5-hour reception, here is the math:

• 2 servings per drinking guest in hour one
• 1 serving per drinking guest in each of the next 4 hours
• A 5-hour reception = 6 planned servings per drinking guest
• 33% assigned to beer = about 2 planned beers per drinking guest

Divide planned beer servings by 24 and round up to a whole case. The optional 20% buffer is applied before the beverage split and container rounding.

Beer Quantities by Guest Count

These 5-hour examples count every listed guest as a drinker and do not include the optional buffer. Beer-and-wine-only assumes a 50/50 split.

Kegs vs Cases: Which is Right for Your Wedding?

Cases (Bottles/Cans)

Consider when: You want packaged servings, several varieties, or no draft equipment

• Pros: No tap equipment needed, multiple varieties are easy, and unopened stock may be returnable when the retailer allows it
• Cons: More packaging and cooler space
• Price check: Compare the local price per 24 servings and confirm return terms

Kegs

Consider when: The venue approves draft service and can support the required equipment, chilling, and service plan

• Pros: Less packaging and a familiar draft-service setup
• Cons: Requires compatible tap equipment, chilling, advance ordering, and staff approved by the venue; verify all return and deposit terms before ordering
• Price check: Include the keg, tap, tub, ice, deposit, delivery, and any service charge

Beer Service Tips for Weddings

• Chilling plan: Follow supplier guidance and confirm refrigeration, cooler space, delivery timing, and responsibility with the venue.
• Ice requirements: Ask the venue or beverage provider to size ice for the beer format, equipment, weather exposure, and service duration.
• Service setup: Use only a setup approved by the venue and beverage provider, with clear product labeling.
• Glassware: Decide between packaged service and glassware with the venue, then include collection and cleanup in the plan.
• Replenishment: Agree on who monitors cold stock and when supplies are replenished during service.

Seasonal Beer Adjustments

Summer Weddings

For an outdoor or warm-condition setup, confirm the chilling plan and make style choices from known guest preferences rather than a generic seasonal ratio.

• Consider a larger share of light, crisp styles if your guests prefer them
• Confirm that the selected styles will be available on the event date
• Have the venue or beverage provider size the ice and refrigeration plan

Winter Weddings

Use the menu and any known preferences to choose styles; do not change the total solely from a generic seasonal percentage.

• Include heartier options (porters, ambers)
• Keep the beer share tied to the confirmed menu and known preferences

Common Wedding Beer Mistakes

• Choosing varieties without evidence: Use direct knowledge of guests and the menu instead of assuming a universal favorite
• Leaving the subtype allocation unreviewed: Reallocate from direct preference information and the menu, not a generic audience assumption
• Forgetting the cooler space: 9 cases of beer takes up significant room - plan ahead
• Leaving chilling unconfirmed: Document equipment, capacity, delivery timing, and replenishment responsibility
