There are a number of citrus peel variations used in gin. With the sheer number of citrus plants around the world, especially in warmer climates, it is one of the main ingredients of gin distillers. From lemon peel to orange, lime, clementine, and others, there’s no limit to the flavor citrus peel can offer. The peel itself is milder than using the full plant. It will add an essence of the fruit without fully infusing a sweeter taste to it. When a sweeter taste is needed the entire fruit might be added.
