Abstract

Steeping without any aeration or bubbling the steep water with nitrogen or carbon dioxide causes retardation of initial germination. However, no elongation of the germination period is needed to obtain malt of normal quality. Thus the malt yield is significantly increased, by 1% when using nitrogen and by 2-2½% when using carbon dioxide. The best results were obtained using carbon dioxide with a steeping procedure involving dry-steeping. The use of a dry-steeping period results in a more even germination.
