  • Description: After the 2022 harvest, seven new varieties of malting barley were registered in the Czech Republic. After three years of testing, spring barley varieties Ambiana, Gingko, Kimberly, KWS Thalis, LG Ludvik, LG Rhapsody and RGT Proxima were registered. Based on the results obtained, LG Ludvik was recommended for the production of beer with the protected geographical indication 'České pivo'. This variety showed low activity of proteolytic and cytolytic enzymes and low level of final attenuation. The other spring barley varieties (Ambiana, Gingko, Kimberly, KWS Thalis, LG Rhapsody and RGT Proxima) gave sweet wort with extract content in malt dry matter ranging from 82.6 to 84.6%. The varieties Ambiana, Gingko, LG Rhapsody and RGT Proxima had extract contents of more than 83%. Proteolytic modification was high (Kolbach Index above 50%) in the varieties Gingko, LG Rhapsody and RGT Proxima. The β-glucan content in sweet wort below 100 mg/l was recorded in the varieties Gingko and LG Rhapsody. Cell wall degradation (friability 85–94%) and final attenuation(81.7–83.0%) were at optimum levels in Ambiana, Gingko, Kimberly, KWS Thalis, LG Rhapsody and RGT Proxima. Gingko, Kimberly and LG Rhapsody always produced clear sweet wort. Low to zero lipoxygenase activity was found in KWS Thalis.
