Bitters

Bitters are concentrated flavoring agents made from various herbs, spices, roots, or fruits, infused into a high-proof alcohol. They have a strong, distinct bitter taste, which enhances the flavor profile of cocktails and other drinks. Originally developed for medicinal purposes, bitters are now primarily used in mixology to balance sweetness and acidity, adding complexity to beverages. Common examples include Angostura and orange bitters, which are key ingredients in classic cocktails like the Old Fashioned and the Manhattan. A few dashes can transform the taste of a drink, making bitters a staple in bartending.
