Anyone who knows anything about cocktails understands the importance of bitters. One drop of these botanically infused mixtures can transform an entire drink, accentuating its rich, warm, sweet, spicy, or acidic flavor profile. Even casual cocktail sippers are sure to have a bottle of bitters on their home bar. The most commonly used are Angostura (rich and warm), Peychaud’s (sweet and floral), and orange (spicy and fresh). However, there are countless types of bitters you may never have tried or heard of. Reach for one of these unique and unusual flavors the next time you’re playing around with your cocktails — or use them in other creative ways such as in sauces, marinades, or to liven up club soda.
