Using the peel of the small, green and rather bitter oranges you find on the Island of Curaçao, the Bitter Bastards Curaçao Bitters are supremely zesty. With carefully measured amounts of bittering agent (gentian root), specially selected spirit (high-proof Dark rum), rapid-maceration and centrifugal extraction, these bitters are perfectly tuned, like a grand piano or a racing car. They'll make your cocktails sing (or possibly roar?).
