What is bitters used for in cocktails?

Bitters are indeed primarily used as a concentrated flavoring agent to enhance cocktails. They are typically very aromatic and add complexity to the drink by introducing a depth of flavor that would otherwise be missing. Bitters are made by infusing various herbs, spices, and other botanicals in alcohol, resulting in a powerful and flavorful liquid that is used sparingly—often just a few dashes per drink.

In the context of cocktails, bitters serve to balance out sweetness and acidity, creating a more rounded and pleasing flavor profile. For example, in classic cocktails like the Old Fashioned or the Manhattan, a few dashes of bitters can transform the overall taste and elevate the drinking experience. The use of bitters is a time-honored tradition in bartending and is crucial for crafting nuanced and well-balanced cocktails.
