In 2004 the following spring barley malting varieties were registered in the Slovak Republic: ADRAN (6), BIATLON (7), BOLINA (6) and BRISE (7). On the average, the newly registered varieties have very good extract contents in malt and strong activity of all followed groups of enzymes. The wort composition generally is on the optimal level too. All four varieties achieved excellent results in yield.In 2004 the following spring barley malting varieties were registered in the Slovak Republic: ADRAN (6), BIATLON (7), BOLINA (6) and BRISE (7).

Laboratory methods of ASBC, EBC and MEBAK recommended for the determination of beer soluble iron (calcium and aluminium in case EBC as well) from the filter aids are compared in the presented article. These official methods diverge under different conditions of analysis. Influence of several parameters (temperature, pH, extraction time, beer sort, etc) on the amount of beer soluble metal ions was examined. Research data demonstrated that the watched parameters influenced the determination of beer soluble ions, therefore these methods give different results.The amount of beer soluble metal ions in industrial scale is lower compared to ones detected...
