The bar bleeds first

The over-pour

Your menu costs a 30ml nip. Your bartender free-pours 40 to 45ml. The guest tastes generosity. Your P&L records a spirit sold at two-thirds of its intended margin — hundreds of times a week.

This is not theft and it is rarely carelessness. It is the absence of a standard. Free-pouring without a jigger drifts heavy under pressure, and Friday night is nothing but pressure. The busier the venue, the worse the drift — which means the loss scales with your best trading nights.

How to detect it:

• Weigh five open bottles at close, and again at close the next night. Compare millilitres poured against nips rung in the POS. The gap is your pour variance.
• Watch one busy service with a jigger standard in place and one without. The difference is measurable within a week.
• Set a pour-cost target by category — spirits, wine, draught — and review it against actuals weekly, not quarterly.

The phantom keg

Eleven kegs delivered. Nine kegs' worth of beer rung through the till. The two missing kegs never appear on any report, because no report exists that would show them.

The gap is real and mundane: foam during service, line cleaning losses, staff drinks poured without a button pressed, comps that never touch the POS, and the first and last glasses of every keg. Individually each is defensible. Untracked, they compound into a share of draught volume that would horrify you if it arrived as a single invoice.

How to detect it:

• Yield-test one keg: litres in the keg versus litres sold from it at your standard glass size. Do it on your highest-volume tap first.
• Ring every staff drink and comp through the POS at zero value. The point is not the dollar — it is the paper trail.
• Log line-cleaning losses per clean. If your cleaning schedule costs you beer, that cost belongs in your pour-cost number, not in the dark.

The house favourite

The signature cocktail is the one on the chalkboard, the one the regulars order, the one staff recommend. Six ingredients, three garnishes, a price set by feel eighteen months ago. It is often the lowest-margin serve on the list — sometimes a loss-maker outright.

Cocktails hide cost in the components nobody costs: the fresh juice squeezed and half wasted, the syrup batch made weekly, the garnish prepped and binned, the ten extra seconds of labour per serve. A cocktail list that has never been costed ingredient-by-ingredient is a list priced by guesswork. The most popular drink amplifies whatever that guess got wrong.

How to detect it:

• Cost your top five sellers ingredient-by-ingredient, garnish and wastage included, against current invoice prices.
• Apply the same star, puzzle, plowhorse and dog matrix you would use on the food menu. Cocktail lists respond to menu engineering exactly the way food menus do.
• Re-cost quarterly. Citrus, spirits and labour do not hold their prices for you.

Poured, not plated

All three losses share one trait: the product disappears at the moment of service. There is no plate coming back to the pass, no portion to eyeball, no leftovers to question. The bar's losses are structural until they are measured — and the measurement takes a stocktake discipline most venues reserve for the kitchen.

The bar deserves the same rigour. It earns better margin than the kitchen on every dollar it takes. Protecting that margin is not a side project. It is the fastest payback in the building.

One week of measurement

You do not need new equipment. You need a standard and a count.

• Jiggers on the well. Non-negotiable, modelled by the head bartender first.
• One keg yield-tested this week.
• Every staff drink and comp rung at zero.
• Top five cocktails costed against current invoices.
• A weekly pour-cost number, by category, on one page.

This is the Evaluate stage of the NEST Method applied to one department — the department that pays back fastest. A bar that measures stops bleeding within a fortnight. A bar that doesn't never knows it started.
