Bourbon, rye, and Scotch whisky each have distinct flavor profiles due to their unique production methods and ingredients. Bourbon, primarily made from corn, offers notes of vanilla, caramel, and oak. It adds sweetness and richness to cocktails. Rye whiskey, with its high rye content, brings spiciness, pepper, and a touch of dryness to drinks. Scotch whisky, made from malted barley, boasts a wide range of flavors depending on the region and production methods. It can offer notes of smoke, peat, fruit, or honey, adding complexity and depth to cocktails.
