Rose hips are a very versatile plant product that come from the fruit of the rose plant. They are rich in vitamin C and are used in wine and tea, as well as beer. They can be added to the boil, though some have experimented with adding them to the secondary as well. They add a floral, citrusy character to beer. For a unique flavor in beer try adding them in specialty style beers to impart a fragrant aroma and taste.
