Flaked barley is an unmalted barley that can be used in stouts and other high gravity beers to help provide head retention and body. It must be used in the mash in order to convert the starches to sugar. Extract brewers must perform a partial mash in order to use flaked barley. A ratio of 1:1 mixture of flaked grains to barley malt is usually sufficient. Use 6 row barley when possible.
Use at 10-25% of total grist
