Half a Teaspoon: What Over-Pouring Actually Costs

Nobody can picture two and a half millilitres. Everybody can picture half a teaspoon.

That is the whole problem with over-pouring. The quantity is too small to argue about, too small to see in the glass, and too small for anyone to feel they have done anything wrong. So it never gets discussed — until it turns up in the margin months later with no obvious cause.

Half a teaspoon, a bottle at a time

A 70cl bottle holds twenty-eight 25ml measures. Add half a teaspoon to each pour and it holds twenty-five and a half.

You have given away three measures from every bottle — a little over 9% of the contents — and not one person could have told you it was happening.

A small bar going through a dozen bottles of spirits a month loses about 370 measures a year. At £4 a measure that is £1,470, on half a teaspoon. A busier one turning over twenty bottles a week is closer to £10,500 a year.

Most pieces on this subject stop at "1,000 drinks poured is two litres lost". Two litres sounds like a spill. Half a teaspoon sounds like nothing, and costs more.

It is rarely anybody's fault

Over-pouring is usually not generosity and almost never theft. Thumb measures drift. Optics wear. A busy Friday produces a different pour from a quiet Tuesday. Free-pouring varies between two people who are both doing their best, and a cocktail with four ingredients has four chances to drift.

None of that is a disciplinary matter. All of it is measurable.

Why it shows up as a GP that slowly slides

This is the mechanism behind a gross profit that goes 74, 73, 72, 70 with no obvious cause. Nothing dramatic happened. Prices did not change, nobody is stealing, and the cellar looks fine. The margin is leaving half a teaspoon at a time, and the only place it becomes visible is in the gap between what the till recorded and what the stock actually moved.

There is a pattern worth knowing, too. The products poured most often are usually poured most accurately — it is the lines people reach for less that drift furthest. That is the opposite of what most operators expect, and it is why an overall spirits figure can look tolerable while individual products do not.

A single stocktake shows you the gap. A series of them shows you whether it is getting wider.

Cocktails widen it

A cocktail specified as 25ml spirit, 15ml liqueur, 20ml syrup and 25ml juice has four measures to drift and a recipe that may exist more firmly on paper than behind the bar.Who has 1 5ml or 20ml thimble measure? Batch-prepared drinks concentrate the same risk into one operation: get the batch wrong once and every drink from it is wrong.

This is why accurate recipes matter more than they look like they should. Without them the theoretical consumption is a guess, and a variance measured against a guess tells you nothing.

The target is consistency, not surveillance

The answer is not standing behind the bar with a measuring jug. It is consistent measures, recipes that match what is actually poured, EPOS buttons that match the recipes, and waste that gets written down. When those line up, the numbers mean something. When they do not, no amount of analysis will rescue them.

If you do not know your current spirit variance, that is the number to ask for. It is on every stocktake we produce, and it is the one that tells you whether the half teaspoon is costing you a few hundred a year or ten thousand.

Hospitality Counts.
