Abstract: The brewing qualities of malts of 4 winter poly-row barley genotypes (Tangra, Pagane, Fanagoriya and 1864-47) from growth seasons 2017, 2018 and 2019 have been studied. They have been developed and cultivated in the trial fields of Dobrudzha Agricultural Institute, General Toshevo. Their protein content is below 12,5% d.m. and meet the criterion for micromalting of two-row barley for brewing. Malt extract from 77,9 to 79,1% d.m. for the vegetation period 2017, from 78,2 to 80,3% d.m. for the 2018 and from 75,3 to 77,4% d.m. for the 2019 was obtained. For the first two vegetation periods, a high degree of malt degradation was achieved, expressed by the Kolbach index (%). The genotypes combine good economic and malt qualities, have the potential to be used for brewing and will contribute to the production of good quality beer.
