For bar owners and bartenders or even the casual bartender at home who wants to save money and improve their alcohol beverage management process there's an easy trick that will help you know how many drinks are left in your bottle of alcohol!

As a preface, I do use fl oz , oz, fluid ounces, and ounces interchangeably to make it easier to read. (We don't use imperial fluid ounces for the sake of simplicity)

How to calculate how many ounces of alcohol are left

That is a question bar managers and bartenders often ask themselves when they're trying to figure out just how much inventory they have. The amount of drink left can be difficult to estimate, but there's an easy trick you can use! In this blog post, we will share the secret behind knowing how many drinks are left in a bottle - without even opening it.

How many ml in a fluid ounce.

A typical drink usually pours 1-ounce the requested spirit.

A U.S. Fluid Ounce (oz.) equals 29.57 mL.

(For our canadian readers converting milliliters to ounces just do the operation in reverse. 1 ounce = 29.57 ml)

Which means that the average shot contains 29.57 ml of alcohol. That number is relevant to everyone who handles liquor bottles. Whether you are a bartender or own a bar, this number is important if you want to know how much of your liquor bottle actually gets poured into each drink.

Estimating how many ounces are left is easy.

We know the most common bottle size (750 ml and 1 liter). Now we need to know how many ounces of liquor are in the most common bottle size to calculate the number of drinks.

We do this by dividing the volume of the bottle by one fluid ounce.

Bottle volume ÷ 1 oz = Number of 1-oz servings

How many ounces are in 750 mL bottle?

Though there are many different alcohol metric bottle sizes, the 750 ml and 1 L bottles are most commonly used by WISK users. Let's use 750 milliliters as example.

We're also going to include a calculator at the end of this article so you can rest easy.

Let’s say your client ordered a margarita. Your drink requires 3 fl oz. of tequila making it 88.71 mL. But how many portions are in that bottle?

750 ml ÷ 1 fl oz => 750 ml ÷ 29.57 mL = 25.36 1-oz portions

Converting 750 ml to fluid ounces suggests there are about 25 1-ounce servings (if you round it down).

How to calculate drink costs?

The formula is the following:

Bottle Price / fluid ounces= Price per ounce

If you had a bottle of SAUZA - ANEJO BLACK BARREL, (at the time of writing, a bottle costs $33.73) it would cost you $3.99 or $1.33/oz.

A tad expensive for a margarita don't you think? Ideally you want to reduce cocktail costs and increase your menu profitability. WISK can help with that.

How many ounces are in a fifth?

25-1 fluid ounce servings if you round it up.

Standard gin bottle sizes

750ml gin bottle: A 750ml gin bottle is the most prevalent size you'll encounter. It is considered a standard and widely available option, offering a generous quantity of gin to enjoy for personal use or when entertaining guests.

1 liter gin bottle: For those seeking a slightly larger gin bottle, a liter of gin provides a bit more than the 750ml size and is suitable for individuals who frequently indulge in gin cocktails or appreciate having a larger reserve on hand.

Magnum: Is a 750ml times 2 its size the quantity for a bottle. 750 ml x 2 = 1.5 ml (magnum).

700ml gin bottle: In certain regions, such as Europe, the 700ml gin bottle is a common size.

Miniature gin bottles: Miniature or "mini" gin bottles are adorable, smaller versions of the regular sizes. This gin bottle size typically holding 50ml to 200ml of gin, these bottles are perfect for sampling different gin varieties or gifting as part of a set.

How many ml in an average bottle of wine?

A typical bottle size of wine in the United States is 750 ml. (Or roughly 25 ounces.)

How many ounces are in a wine bottle?

Using the same mathematics as above. Once again we divide the volume of a standard wine bottle by one ounce.

750 ml ÷ 1 oz => 750 ml ÷ 29.57 mL = 25.36 1-oz portions

How many glasses are in a bottle of wine?

When pouring a wine glass, we usually consider it to be 5 or 6 fl oz. (150–180 ml). A bottle will serve about 5 or 6 wine glasses(roughly 5 fluid ounces per serving) in your average bottle.

Though sometimes large format bottles such as 1L and bigger could have more than 7 wine glasses depending on the pour!

What if my bottle size changes?

Let's say you have another bottle but in a different format: Absolut Vodka 1L.

1000mL ÷ 1 fl oz => 1000 mL ÷ 29.57 mL = 33.81 portions of 1 fluid ounce.

Your pour costs for 3 fl oz of vodka. would be $2.39 or $0.79/fl oz.

P.S. All of that is automatically calculated in WISK.

How to calculate how many shot glasses (1.5-ounce shots) are left in that alcohol bottle?

This part is going to be short and sweet.

We know that in a 750 ml bottle there is 25.36 fluid ounces. Since a traditional shot glass(jigger) is 1.5 fl oz. We multiply the 29.57 mL we had previously by 1.5.

29.57 x 1.5 = 44.36 mL

And lastly, 750 ml/44.46 mL = 16.90 shots.

Easy peasy right? No? If so, stick with me, i'll make your life easier at the end of this post with a calculator that does the work for you.

Pouring a shot

How to measure how many drinks are left in a partially full standard 750 ml bottle?

Now that you know how many 1-oz servings are in each of your bottles, it’s time to dig a little deeper. How many shots is the bar pouring in each drink? Is the shot size of .5 oz, 2.5 oz, or 5 oz? Whatever the size of the pour, it’s easy to translate that so bartenders can estimate how many drinks are left in a bottle.

Ounces in full bottle × remaining % = Drinks left in partially full bottle

Going back to that absolut, say that I use a 1-oz pour of my vodka, and I have 50% of my 1000ml bottle of vodka ( I have 50% of 33.81 1-oz portions in my bottle):

33.81 servings × 50% = 33.81 × 0.5 = 16.90 1-oz servings left

How to measure a different pour size

But what if your cocktail asks for a different amount of alcohol or your glasses change? Then we need to know how many servings of that new pour size exist in that bottle. We can find this by dividing the number of remaining 1-oz pours by the new pour size (in ounces):

Number of 1-oz servings ÷ new pour size in ounces = Portions of new pour size

Let’s take a 3-oz pour as the example. After measuring with your scale, WISK shows you that you have 17.27 1-oz portions of liquor left. I just need to divide that by my 3-oz base pour to figure out how many drinks of the new-sized pour remain:

17.27 1-oz portions ÷ 3 oz = 5.76 3-oz servings

In this case, I have about 5 full drink pours left in that liquor bottle.

And don't forget to check the top diameter (mouth-size of the container or bottle). Measure the top diameter of the glass or container you plan to use. This measurement can affect how the liquid flows and may impact the pouring process.

Fluid ounce to milliliter conversion

How many milliliters are there in us fluid ounces. To convert fluid ounces (fl oz) to milliliters (ml), you can use the conversion factor of 1 fl oz = 29.57353 ml (rounded to 5 decimal places).

So, to convert a certain number of fluid ounces to milliliters, you would multiply that number by the conversion factor.

32 fluid ounces is equivalent to approximately 946.35 ml.

Here's another example: 24 fl oz to ml.

24 fl oz x 29.57 ml/fl oz = 710.34 ml

How many 8 fl oz glasses are in 750ml?

750 ml to cups (8 fl. oz.)? Remember this formula:

Number of 1 fluid ounce servings ÷ new pour size in ounces = Portions of new pour size

750 ml ÷ (29.57 mL x 8) is equal to 3.17 glasses in a 750 ml bottle.

How many beers are in a keg?

The typical keg comes in a few sizes – 20L, 30L, 50L, and 58.6L and occasionally 12L.

So let's start with the most common question we get:

How many ounces are in a pint:

How many oz.? There are 16 ounces in a standard pint. That means there's approximately 473.176 ml in a pint.

How many beers are in a 12L keg?

12 000 mL / 29.57 mL = 405.816 ounces are in a 12L beer keg.

If you divide by the regular pint size, each 12 L keg of beer has 25.36 pints per keg.

How many beers are in a 20L keg?

20 000 mL / 29.57 mL is = 405.816 fluid ounces are in a 20L keg.

Again, if you divide by the pint size, each 20 L keg of beer has 42.2675 pints per keg.

How many beers are in a 30L keg?

30 000 mL / 29.57 mL = 1014.54 fl oz in a 30L keg.

And adding the last step: each 30 L keg of beer gives 63.40 pints per keg.

How many beers are in a 50L keg?

50 000 mL / 29.57 mL = 1690.90 fluid ounces in a 50L keg.

If you divide by the regular pint size, each 50 L keg of beer gives 105.67 pints per keg.

How many beers are in a 58.6L keg?

58 600 mL / 29.57 mL = 1981.87 fluid ounces are in a 20L keg.

Continuing the usual math:

Each 58.6L keg of beer gives 123.84 pints.
