What role do bitters play in cocktails?

Bitters play a crucial role in cocktails by providing a complex flavor that balances the sweetness of other ingredients. They are concentrated infusions made from various botanicals, including herbs, spices, and fruits. This complexity contributes to the overall flavor profile of the drink, helping to create a more harmonious balance between sweetness, sourness, and bitterness.

While some people may think bitters are purely for garnish or to dilute alcohol, their primary purpose lies in enhancing the drink's flavor complexity. By adding depth and a range of aromatic qualities, bitters help to elevate cocktails, making them more enjoyable and sophisticated. This is especially important in crafting well-balanced cocktails, where the interplay between different taste elements can significantly affect the overall experience.
