How many pours you really get from a bottle, a pricing formula with waste built in, worked examples and a free calculator to price your by-the-glass list.

Wine by the glass is often the highest-margin line on the list and the easiest one to lose money on without noticing. The bottle cost is known, the price looks generous, and the leak is quiet: half a bottle poured down the drain on Thursday, a heavy pour on Saturday, a glass price nobody has checked since the distributor raised the bottle cost. This guide shows how to price a glass with waste built in, how many pours you really get from a bottle, how to read the one number that decides your by-the-glass pour cost, and a free calculator to price your own list.
The traditional rule is that the first glass pays for the bottle: if the bottle costs $12, charge $12 for a glass and the other four pours are margin. On paper that is a 20 percent pour cost. In practice it is rarely 20 percent, for three reasons:
That is why realistic by-the-glass pour cost runs 25 to 35 percent once waste is counted, the range we use in the beverage program guide. The aim of pricing is to land inside that range on purpose, with waste in the math, instead of landing there by accident.
A standard 750 ml bottle holds about 25.4 ounces. Divide by the pour size to get the pours in a bottle, then remember that the last half ounce is often sediment, spills or the taste the server pours to check the bottle.
| Pour size | Pours in a 750 ml bottle | Common use |
|---|---|---|
| 5 oz | 5.1 | Standard glass of still wine |
| 6 oz | 4.2 | Generous glass; check your glassware can hold it with room to swirl |
| 4 oz | 6.3 | Sparkling in a flute, dessert wine at 2 to 3 oz |
| 8.45 oz (250 ml) | 3.0 | Quartino or carafe: a third of a bottle |
| 2 to 3 oz | 8 to 12 | Tasting pours and flights |
Pick one pour size per glass type, write it on the list, and make it easy to hit: pour-line glasses, a measured carafe or a jigger for wine. If the glass is 16 ounces and the pour is 5, a free pour will be 6 or 7 every time because a 5 ounce pour looks small in a big glass.
Price from the bottle cost, your target pour cost and the number of pours you realistically sell from each bottle, not the number the bottle holds:
Pours sold per bottle is the honest version of "pours in a bottle". It comes from your own numbers: glasses sold of that wine for the week (from the POS) divided by bottles used (opening count plus received minus closing count, from the bar inventory). A 5 ounce program that sells 4.5 pours per bottle is running well. Under 4 means bottles are dying open or pours are heavy.
Then round to a clean menu price. Most lists step in whole dollars ($11, $13, $15) and avoid prices ending in 99 cents, which read as retail.
Three wines from a full service list. The house red sells fast, so 4.5 pours per bottle is realistic. The premium red carries a slightly higher target, the sliding scale from the beverage guide applied to the glass: a lower percentage on the cheapest wine and more dollars on the better one. Sparkling loses its bubbles quickly, so it is priced on four pours sold.
| Wine | Bottle cost | Target pour cost | Pours sold per bottle | Exact price | Menu price | Real pour cost | Profit per glass |
|---|---|---|---|---|---|---|---|
| House Cabernet | $12 | 25% | 4.5 | $10.67 | $11 | 24.2% | $8.33 |
| Pinot Noir | $22 | 28% | 4.5 | $17.46 | $18 | 27.2% | $13.11 |
| Prosecco | $14 | 28% | 4 | $12.50 | $13 | 26.9% | $9.50 |
Two things stand out. The house red at $11 makes about $8.33 a glass at a 24 percent pour cost, close to the old first-glass rule but with waste already counted. And the premium red makes more than $13 a glass at a higher percentage, which is the point of the sliding scale: percent margin is how you check the list, dollar margin is how you pay the rent.

Pours sold per bottle is glasses sold divided by bottles used for the same week. A 5 oz program that sells 4.5 pours per bottle is doing well; under 4 means bottles are dying open.
Keep the same $12 bottle and the same $11 glass, and change only how many pours you sell before the bottle is dumped:
| $12 bottle at an $11 glass | Sales from the bottle | Pour cost |
|---|---|---|
| 5 pours sold, nothing wasted | $55 | 21.8% |
| 4.5 pours sold (half a glass lost) | $49.50 | 24.2% |
| 4 pours sold | $44 | 27.3% |
| 3 pours sold | $33 | 36.4% |
Same wine, same price, and the pour cost runs from about 22 percent to 36 percent depending on what happens to the last third of the bottle. That is why the fixes for a high by-the-glass pour cost are mostly operational, not pricing:
The Beer and Wine Inventory and Order Guide tracks every bottle by the glass and by the bottle, works out usage and pours sold, and builds the order from pars. Excel and Google Sheets, one-time purchase.

Five free calculators turn these guides into results in a few minutes: prime cost, food cost, labor cost, break-even and pour cost. Each one shows the gap to the benchmark for your concept in dollars a year. No signup.

A 750 ml bottle holds about 25.4 ounces: about five 5 ounce glasses, a little over four 6 ounce glasses, or three 250 ml quartinos. Price on the pours you actually sell, which is usually a little less.
Most restaurants run 25 to 35 percent once waste from open bottles is counted. The old first-glass-pays-for-the-bottle rule is about 20 percent on paper, but only if every pour in the bottle sells.
It is a useful starting point, not a rule. It assumes all five pours sell. Price with waste built in instead: bottle cost divided by target pour cost divided by pours sold per bottle.
Most still wines hold for two to three days with a stopper, less for sparkling and delicate whites. Vacuum stoppers add a day or two, and inert gas or needle-through-the-cork systems keep bottles much longer, which makes premium wines by the glass practical.
