Do Bitters Ever Go Bad?
Bitters are a highly concentrated alcohol-based infusion of herbs, roots, and spices that are used to add flavor to cocktails and other drinks. They are shelf-stable and do not spoil or go bad over time. However, their potency and flavor profile may change slightly over a long period due to evaporation and oxidation. Proper storage, such as keeping them tightly sealed and away from direct sunlight, can help prolong their lifespan.
