Over-Pouring

What over-pouring actually means

Over-pouring is when the bartender puts more liquor in the glass than the recipe says. Spec says 1.5 oz of vodka, they pour 2 oz. It is the single biggest source of shrinkage in most bars, and it is rarely malicious. Most bartenders over-pour by habit, not by intent.

The impact on margin is brutal because it compounds over hundreds of drinks a shift.

How it shows up on the floor

Over-pouring takes three forms. The first is unintentional: the bartender free pours by count and their count is too slow. The second is friendly: they heavy-hand regulars, industry workers, or friends. The third is intentional: they over-pour to get bigger tips or trade drinks for favors.

All three cost the same money. The first two are fixable with training. The third is a termination issue.

The math behind it

The math is simple and depressing. If every 1.5 oz pour becomes 1.75 oz, you have added 17 percent to the cost of every drink without adding a penny to revenue. Pour cost jumps from 20 percent to 23.3 percent. That 3.3 points of pour cost is pure profit that just walked out the door.

Example: a bar doing $60,000 a month in liquor sales loses about $2,000 a month to a consistent 0.25 oz over-pour. Annualized, that is $24,000. More than most people’s rent.

How to catch it

Pour tests are the direct method. Variance analysis is the indirect one. If your theoretical pour cost says 20 percent and your actual pour cost is 24 percent, you have a leak. Over-pouring is the most common explanation before you get to theft.

Per-SKU variance is even better. If vodka variance is flat but tequila variance is 8 percent high, you know exactly where to look.

Common causes

Free pouring without counting. No jiggers on the bar. Unclear recipe specs. Bartenders who worked at higher-end bars where pours were bigger. No accountability because management never runs the numbers.

How PourIQ handles it

PourIQ calculates theoretical vs actual usage per SKU per shift. When a bottle should have lasted 200 pours but only delivered 180, it flags the over-pour before it becomes a monthly variance surprise. You know which bottle, which shift, and which bartender was working.
