Often used in white beers, lambic, grand cru, etc. Gives a fuller flavour and increases the head. Can be used up to 20-40 % without significant problems. At higher percentages filtering/lautering the grain bed becomes very difficult and extra husks may need to be added to prevent the filter bed from clogging up. Contains gluten.
Adding flakes to the mash gives a more drinkable beer and affects the flavour and colour. Because of the production process of the flakes, they may be simply added to the mash. They should not be pre-cooked.
