Pour Cost 101: Why Your Bar Is Hemorrhaging Profit and How to Stop It

The bar is supposed to be your highest-margin revenue center. A well-run bar program should generate 75–82 cents of gross profit for every dollar it brings in. For most operators, however, the bar is quietly leaking money in ways that don't show up until a full-period audit — and by then, thousands of dollars are already gone.

The metric that controls this is pour cost — also called beverage COGS. If you're not tracking it by category, you're managing your bar by feel. That's expensive.

What Is Pour Cost?

Pour Cost % = Beverage COGS ÷ Beverage Sales × 100

Just like food cost, it measures what fraction of your beverage revenue went to the cost of product consumed. The formula itself is simple. The challenge is in getting accurate, timely data — and separating it by category so you can actually see where the problem is.

Benchmarks by Category

• Draft Beer: 20–26%
• Bottled / Canned Beer: 22–28%
• Wine (by the glass): 28–38%
• Spirits / Liquor: 18–24%
• Cocktails: 20–28% (varies significantly by spec complexity)

Why Blending These Numbers Hides Problems

A single beverage COGS percentage that lumps beer, wine, and liquor together is almost useless for management purposes. A tight liquor program can mask a bleeding draft beer program. An excellent wine margin can hide over-pouring on cocktails. You think you're at target — but the number is lying to you by averaging away the signal.

Separate tracking by category is the only way to pinpoint exactly where margin is being lost, and it's the only way to assign accountability to the right person or process.

The Six Most Common Reasons Pour Cost Runs High

1. Over-pouring. A bartender consistently pouring 1.25 oz instead of the specified 1 oz is giving away 25% more product than you're charging for — every single drink, every single shift.
2. Comp abuse. Drinks comped to friends, regulars, or social media "influencers" without management authorization or proper tracking.
3. Spills and breakage. Real cost that isn't logged against revenue. On a busy Friday night, untracked spill cost can run $50–$200 depending on your volume.
4. Theft. Cash drinks not rung in, a bottle taken home, or bartenders pocketing the difference from under-pouring. Uncomfortable to think about, common in practice.
5. Wrong pricing. Cocktail ingredients changed due to substitutions or premium upgrades, but prices weren't updated to reflect the new cost.
6. Incorrect bottle size purchasing. Specs written for 1L bottles but purchasing 750ml. Your cost per ounce is higher than the recipe assumes.

How to Calculate Your Actual Pour Cost

For each beverage category, you need three numbers:

• Opening inventory value (beginning of period)
• Plus: purchases received during the period
• Minus: closing inventory value (end of period)

The result is your cost of beverage consumed. Divide by beverage sales in the same period for that category.

What to Do When It's Too High

Start with the category furthest from its benchmark target. Then work through this sequence:

1. Audit your pour specs. Pull out the jigger and actually measure what's going into each cocktail on your menu during service. Compare to spec. You may be surprised.
2. Check POS voids and comps by bartender. Consistent over-voiding or comp patterns by a specific staff member tells a clear story.
3. Count liquor inventory mid-period. A mid-week count against sales lets you calculate a real-time pour cost. If it's wildly different from your end-of-period number, something is happening during specific shifts.
4. Price-check your highest-volume cocktails. Calculate the actual cost of each cocktail based on current product cost, not what you costed it at when you opened or last updated the menu.

The goal isn't to catch anyone doing anything wrong. The goal is to build a system where the numbers tell the story before the damage adds up — and your team knows those numbers matter.
