Abstract
The primary objective of barley steeping is to provide the grains with an optimum amount of water to guarantee quick and uniform germination. For that purpose, also, oxygen supply and carbon dioxide removal are needed. Measurements on different steeping systems show that inhomogeneity of the steeping barley leads to a higher percentage of poorly modified grains, thus reducing the overall quality of the malt. Circulation during steeping ensures homogeneity and improves malt.
