Bitters, a staple in mixology, are concentrated and aromatic liquids crafted by infusing a variety of herbs, spices, roots, and botanicals in alcohol or glycerin. These potent elixirs contribute an essential layer of complexity to cocktails by imparting a nuanced bitterness and a spectrum of herbal, citrus, or spiced notes. Traditionally used in small dashes or drops, bitters can elevate the flavor profile of a drink, balancing sweetness and acidity while enhancing overall depth.
