How Much Alcohol for a 75-Guest Wedding

The full shopping list for 75 guests

This is a 4-hour open bar at the wine-leaning default of 25 percent beer, 50 percent wine, and 25 percent liquor, with a 20 percent overage buffer already built in. Every quantity rounds up, because running dry is worse than a few unopened bottles you can return.

Where the numbers come from

The list is generated by the same engine as our wedding alcohol calculator: one drink per guest per hour, a 20 percent buffer, then published yields of 5 pours per wine bottle, 24 beers per case, and 22 cocktails per liter at a 1.5 ounce pour. The 100-guest list walks through every conversion line by line. What's below is what's specific to 75: the bartender ceiling, and the signature cocktail math.

One bartender at the ceiling

Seventy-five is not a round number by accident here. It's exactly where our staffing formula, one bartender per 75 guests, hits its limit before rounding up to a second hire. That makes 75 guests the largest wedding where a single, experienced bartender is still the standard call for a beer, wine, and simple mixed-drink bar.

The formula assumes steady pacing across the night, not everyone arriving thirsty in the first ten minutes. A single bartender at exactly 75 guests will feel the opening-hour rush more than one covering 50, so don't be surprised if the first round takes a little longer than the rest of the night.

When to add a second anyway

A handful of situations push past the one-bartender math even at 75 guests. A full craft-cocktail menu is the biggest one: shaken and stirred drinks take a minute or more each, while pouring wine or popping a beer takes seconds, so the same headcount needs more hands once the drinks get complicated. A single bar station with no second line, a hot outdoor reception where guests hit the bar hard and early, or a bar open longer than the standard 4 hours are the other common triggers. If two or more of those apply, book a second bartender before the day, since a mid-event add is rarely possible.

Signature cocktail batch for 75

If you're serving a signature cocktail during cocktail hour, plan on one per guest. At a 1.5 ounce pour, 75 drinks is 113 ounces of the base spirit, which is about 4 one-liter bottles (or 5 standard 750ml bottles), plus mixer, citrus, and garnish for 75 servings. Buy that on top of the base list above rather than folding it in. Batching it ahead of time also takes real pressure off the single bartender covering this size, since a pre-mixed pour is nearly as fast as opening a beer.

What a 75-guest bar costs

The list above sizes the bar; it doesn't price it. As an editorial estimate, the alcohol and mixers alone run about $9 to $13 per guest at typical US retail prices, which is roughly $638 to $954 for the whole 75-guest order. That figure is our own construct, built from the exact bottle counts above times common retail price bands (wine around $12 to $18 a bottle, beer $24 to $34 a case, liquor $22 to $34 a liter). It is not a quote, and it excludes labor.

A single bartender for a 4-to-5-hour reception typically runs $35 to $75 an hour, plus the $50 to $100 tip. If you're adding a second bartender for any of the reasons above, budget that as a second full labor line, not a small add-on.

Adjust the mix to match your crowd

The 25/50/25 wine-leaning split is a safe default for a mixed guest list, but it's not the only option. A cocktail-forward crowd runs closer to 25 percent beer, 25 percent wine, and 50 percent liquor, which shifts bottles toward spirits. A craft-beer crowd leans beer-forward at 40/30/30. Skipping spirits entirely to keep it simple? A beer-and-wine-only bar goes wine-heavy at 40/60 and drops the liquor, mixers, and a chunk of the labor.
