Bitters from a culinary perspective.... Concentrating on single ingredients, Bob's Bitters can be used in a controlled fashion by bartenders to add specific flavors to drinks. This is a very different approach compared to traditional bitters, which usually combine many spices and botanicals to create a complex ingredient. this inevitably adds an intricate mixture of flavors to a drink. Bob's approach to bitters is different. His bitters are a valuable tool for bartenders seeking to add specific flavors, rather than the intense mixture of flavors most bitters offer.
