Cara 20 (Caravienne) malt is a very light caramel malt that is produced in the roasting drum. Due to caramelization and low temperatures during the drying process, this malt gets its very specific flavor. When you use as little as 5% of this malt in your beer, its head retention will significantly improve.
Flavor: Light caramel
