How much margarita mix do you need for one bottle of tequila 750ml?

Answer 1

usually mixes come in two sizes, 1 quart and 2 quart, some may also be 1 gallon (usually commercially sold, not retail). Depending on the mix the usual quantity is 2 parts or 3 parts to one (essentially twice or three times as much mix as liquor).

The typical bottle of liquor is 750 ml, as you mention (this is not a fifth, a fifth is 908 ml, or 1/5 imperial gallon), erroneously referred to as a fifth, meaning approximately 1/5 a US gallon, (actually slightly more). So the amount of mix you would use is about 1 1/2 liters to 2 1/4 liters, for a 750 ml bottle of tequila.

A good margarita recipe not using a mix is 1 ounce tequila, juice of 1/2 a lime, 1/2 ounce simple syrup (50/50 sugar and water). mix the ingredients in a shaker with ice, strain into a salted margarita glass, float a splash of Cointreau on top of the drink and garnish with a twist of lime.

For a frozen margarita two jiggers of mix, 1 shot of tequila mixed with a glass of shaved ice, and a splash of Cointreau.
