Underberg Herbal Bitters have been the standard of quality for European digestifs for more than 150 years. Crafted with a secret mix of herbal essences in Germany, these potent bitters are famous for their balanced complexity. Though Underberg recommends this aromatic beverage as a post-meal digestive aid, we know for a fact that professional bartenders and home mixologists both use these bitters to make unforgettable cocktail creations.
