how many cocktails in half gallon?

The number of cocktails you can make from half a gallon depends on the size of each cocktail. A standard cocktail typically contains about 4 to 6 ounces of liquid. Therefore, half a gallon (which is 64 ounces) could yield approximately 10 to 16 cocktails, assuming an average serving size. Adjustments can be made based on the specific recipe and ingredients used.
