Blue Raspberry flavor originates from Rubus leucodermis, more commonly known as the “whitebark raspberry” or “blue raspberry” for the blue-black color of its fruit. The flavor is described as somewhere between tangy and sour. The color blue is rare among edible plants and animals. Wave Blue Raspberry Vodka is distilled from a base of 100% corn, which typically gives vodka a lightly sweet taste that blends quite well with the heavy flavors. Most flavored vodkas start at almost double the cost of Wave Vodka.
