To be honest, exploring the different types of cocktail bitters can get a bit overwhelming since you’ll come across lots of the kinds with other uses and ingredients. But to give you a sneak peek at cocktail bitters, here are the most popular types: - Aromatic Bitters: This bitters type is the oldest and most commonly used bitter of all. The most famous brand is Angostura aromatic bitters made up of gentian root, Angostura bark, and many different aromatic herbs and spices. - Citrus Bitters: These bitters are infused with peels of citrus fruits like orange bitters, lemon, grapefruit, and even lime. As expected, this lends a sweet taste to the drink. - Herbal Bitters: Herbal bitters offer the most options when it comes to flavor and aroma. The herbs used range from ones with strong flavor and taste (thyme, mint, and tarragon) to spices that impart warmth (cinnamon). - Bean and Nut Bitters: Regarded as the latest discovery in the bitters industry, these are taking the world by storm. The popular beans used are chocolate and coffee, while macadamia, pecan, and walnut are the widely used nut options
