The short answer? Yes. Measuring your cocktail ingredients helps ensure that you can consistently make and serve a quality cocktail, every time. An easy way to make cocktail measurements is with a jigger. Jiggers are a helpful tool for measuring exact ingredient amounts. If you don’t have a jigger, grab a measuring cup from your kitchen. As a rule, taking the time to properly measure your ingredients is key to crafting the perfect cocktail, again and again.
