Pour Test

What a pour test actually means

A pour test is when a manager stands a bartender up, hands them a bottle, and asks them to pour a 1.5 oz shot into a measuring glass. Then you measure what they poured and see how far off they are. Simple, direct, uncomfortable for the bartender, and incredibly effective.

It is the fastest way to figure out if your over-pour problem is one bartender or all of them.

How it is used on the floor

The standard setup: pour into a graduated cylinder that reads in quarter-ounce increments. Have each bartender pour what they think is a 1.5 oz shot three times into water glasses. Then measure each one and write down the results.

A well-calibrated free pourer hits within 0.1 oz of spec. An average bartender is within 0.25 oz. A bad one is routinely pouring 2 oz when the spec is 1.5. That 0.5 oz per drink on 80 drinks a shift is 40 oz, or about 1.5 bottles of liquor, given away every shift.

The real cost of a failed pour test

Example: one bartender pours 1.75 oz instead of 1.5 oz. That is 0.25 oz extra per drink. On 100 drinks per shift, that is 25 oz extra, or roughly one full bottle of liquor. At $25 a bottle wholesale and $8 menu price per shot, that is $25 in lost product and $200 in lost sales revenue per shift. Across a year, one bartender pouring 0.25 oz long costs the bar over $40,000.

Pour tests are free. Not doing them is expensive.

When to run them

New hires should pour test in week one and month one. Existing staff should test quarterly or any time variance spikes on a specific shift. Many operators run a “pour check day” every 90 days with all staff.

Some bars make it routine and non-punitive. Others only run them when something is already wrong. The first approach works better.

Common mistakes

Only testing when you suspect a specific person (breeds resentment). Testing without the bottle angle and speed they actually use on the floor (everybody pours slow when watched). Not documenting the results so you can track improvement.

How PourIQ handles it

PourIQ does not replace the physical pour test, but it tells you exactly when to run one. When variance spikes on a specific SKU or a specific shift, it flags the pattern so you know whether the problem is the bottle, the brand, or a specific bartender. The pour test becomes targeted, not random.
