Drink mixers are ingredients used to combine with alcoholic beverages to create cocktails or mixed drinks. Common mixers include soda, juice, tonic water, and syrups. They enhance the flavor of the drink and can also add sweetness, acidity, or carbonation. Mixers can be used in various proportions depending on the desired taste and strength of the drink. Popular cocktails like the Mojito or Margarita rely on specific mixers to achieve their signature flavors. Understanding how to balance mixers with spirits is essential for crafting enjoyable beverages.
