20 °L - Briess Malting - A medium Belgian Crystal malt that provides a slight toasty flavor and residual caramel sweetness. Caramel Vienne (also known as Caravienne) is commonly used by Belgian breweries in producing Abbey or Trappist style ales. Caravienne and Caramunich have a different flavor contribution than the Crystal malts listed above. Some describe the flavor as slightly toffeeish.
