Beer adjuncts & additives are used to enhance a characteristic of beer. Most adjuncts and additives are used to improve beer, add unique flavorings or aroma to beer. Some are even used to alter the way the beer ferments. Common types are chocolate, coffee, and fruit. Fruit helps contribute different flavors to popular beers including blueberry, raspberry, and limes. Adding fruit to beer also usually means more alcohol due to the additional sugar content.
