Product waste accounts for thousands of dollars in lost profits at bars each year. Human error is just a part of the job. One of the most important skills a bartender can have is preventing that waste from occurring. When you finish a bottle of liquor, for example, having properly trained bartenders should mean you sold the maximum number of drinks possible from that bottle. This is a great way to determine waste, keep track of sales, and even recognize stealing. We’ll go over the tricks of the trade you can use to determine how much liquor is left in your bottles so you can get a better look at your bar’s functionality.
How to Calculate How Many Ounces of Alcohol Are Left
The secret to figuring out how many ounces of alcohol you have left in your bottles requires just a little bit of math. Don’t worry – the math is simple, and any good bartender should already know the number of ounces that go into each corresponding drink type we mention. First, we should go over some basic conversions.
How Many mL in a Fl. Oz?
A US fluid ounce equates to 29.57mL. You’re probably wondering why in the world we in the US use this strange form of measurement at this point. Alas, there are some things you never grow out of, and for us, it’s the Imperial System.
How Many Oz in a 750mL Bottle?
In ounces, a 750mL bottle is 25.3605oz rounded. It’s not really an attractive number, is it? For the purpose of calculating how much you have left in your bottles, however, it’s perfect.
Portions by Alcohol Type and Pour Size
Now that we’ve gone over the basic stuff, we can get into the calculations. When we talk about the amount left in a bottle, we really just want to know how many servings are left. Knowing your servings can help you determine how much each unit you open and sell should bring and how much you might be missing. You can look at this information based on how many wine bottles you’ve sold vs how many bottles you’ve gone through, for example. If there are discrepancies, you can research them further to avoid more profit loss.
- Liquor: Bottle volume / 1oz = number of 1oz servings.
- Wine: Bottle volume / 5oz = number of standard wine pours.
- Beer: Keg volume / 16oz (1pt) = number of beers per keg.
Partially open bottle? Estimate the volume left and multiply that calculation by the percentage of the corresponding calculations above. (Example: An estimated 10oz of tequila is left in a bottle. Using the calculation for liquor, that would mean there are 10 servings left.)
It’s just that simple, and you should definitely compare it to your bottles out to see how well your bartenders did on pours. If you notice a lot of product missing, it might be time to retrain your bartenders on how to measure their pours.
