Cocktail mixers are non-alcoholic ingredients used to enhance the flavor and presentation of cocktails. Common mixers include soda, tonic water, fruit juices, and simple syrup. They help balance the taste of stronger spirits, making drinks more enjoyable and accessible for a wider audience. Mixers can be used in various combinations to create classic cocktails like the Mojito or Margarita. They are often available in pre-packaged forms, allowing for quick and easy preparation at home or in bars. Understanding how to use different mixers can elevate the cocktail experience for both novice and experienced drinkers.
