TECHNOLOGICAL PROPERTIES OF WORTS OBTAINED FROM MALTS OF NAKED BARLEY GRAIN

Abstract The purpose of the research was to determine the effect of diversified nitrogen fertilization (0, 25 and 50 kg•ha-1) on selected properties of grains, malts and brewing worts. Brewing value of barley grain was determined by Molina-Cano method. It was stated that the higher doses of nitrogen caused an increase of yield, as a result of stronger productive tillering of plants. Significant growth of grain yield was obtained by the in-creasing of nitrogen fertilization from 25 to 50 kg•ha-1. Malts from naked barley grain were produced in the same way as malts of the Pilznen type. According to Molina-Cano method, the naked barley grain of Rastik cultivar was qualified as brewing, because of high malt extractivity. Laboratory worts were characterized by a high extract content, but not suitable viscosity, total attenuation and low soluble nitrogen content.
Keywords: naked barley, nitrogen fertilization, malt, wort
