Speaking of bottle capacity，Liquor bottle sizes come in a wide range of shapes and sizes, from small 50ml “nip” bottles to large 1-gallon jugs.
Knowing how many glasses are in a bottle will help you stock your bar and plan your party. For example, a standard 750ml bottle (also known as a “fifth”) is 25.4 ounces. This yields about 16 shots of spirit, and if it’s a base spirit such as vodka, tequila, or whiskey, you can usually expect 16 cocktails from a bottle.
However, wine bottles come in a variety of sizes, and drink recipes don’t use the traditional 1 1/2 ounces of each wine. A few charts can take the guesswork out of estimating how much booze and mixers you’ll need to make the drinks you plan to serve.

The number of cocktails that can be made from a bottle of wine varies by drink. When estimating your needs, it can be helpful to know the average serving size of a cocktail.
Drinks per bottle
Most distilled spirits and wines are available in 750ml bottles. Some alcohol producers also offer pints, half pints and liters, while wine can also be sold in micro-bottles. The largest size (magnum and handle) is extremely rare, so don’t expect to find many of these.
