Coriander seeds are most commonly used in the brewing of Belgian Witbier. They are small seeds that are cracked and added to the end of the boil in order to contribute a lemony, spicy flavor and aroma to beer. These flavor and aroma characteristics work well in conjunction with other herbs, fruits and spices, such as orange peel, lemon peel and lemongrass. They can be used in any beer where a lemon citrus and slightly spicy flavor is desired. Coriander may also be used in Grand Cru, Belgian wheats, or in any beer your mind can come up with!
