When making cocktails, many recipes call for ratios and measurements like "parts." How many ounces is a sip? This depends on the glass size, your drinking habits, and the specific drink. On average, a sip is about 15 mL. Regardless, you should always drink responsibly and track your drinks to avoid overdoing it.
If you want to be extra cautious, try using a smaller glass when mixing your drinks and only filling them up to the halfway mark (or about 8-12 ounces). That way, it'll take fewer sips for you to finish the entire beverage. You should also keep in mind that the amount of alcohol in your body will affect how quickly it takes you to finish a beer or other beverage.
How many sips it takes for you to finish a drink can also vary based on the beer's size and ABV. Additionally, the rate at which you drink can impact this number, as well as how your metabolism works.
If you're not sure how much a sip is, you can use a tool that measures volumes and ounces called a jigger. This dual-cup bar tool is commonly used by bartenders to accurately measure cocktail ingredients. You can also use a measuring spoon to measure volume, as each tablespoon holds about half an ounce. Alternatively, you can find small-angle measuring cups that can be used for precise mixing.
