How much alcohol for 150 wedding guests?

Here's a ready-to-shop estimate for 150 guests at a typical 5-hour reception (average-drinking crowd, 10% buffer included). Need different assumptions? Open the alcohol calculator to adjust and get a copyable shopping list.

Quick answer

For a 5-hour reception with an average-drinking crowd of 150 guests, plan for about 991 drinks. With a full bar that's roughly 100 bottles of wine, 298 beers, and 13 bottles of liquor, plus 25 bottles of champagne for a toast. These figures include a 10% buffer.

Total drinks by reception length

A longer reception means more drinks per guest (the first hour counts double).

Crowd matters too: a lighter-drinking group of 150 needs about 743 drinks over 5 hours, while a heavy-drinking crowd needs closer to 1,238.

Bar setup for 150 guests

Around 150 guests, a single bar tends to back up during the rushes right after the ceremony and after dinner — a second bartender or a self-serve wine-and-beer station keeps things moving. Batching one signature cocktail ahead of time noticeably cuts the wait.

How the estimate works

The math is simple: plan about 2 drinks for the first hour and 1 drink per hour after that, per guest. For 150 guests over 5 hours that's roughly 991 drinks once a 10% buffer is added. We split a full bar about 50% wine, 30% beer, and 20% liquor, then convert: a wine bottle pours 5 glasses, a 750ml liquor bottle makes ~16 drinks, and a champagne bottle gives 6 toast pours.

Serve responsibly

Serve only guests of legal drinking age, use a licensed and insured bartender, keep water and non-alcoholic options out, and help guests arrange a safe ride home. Host and dram-shop liability rules vary by state.

These are planning estimates based on common rules of thumb — confirm quantities with your caterer or bartender.
