Hop breeding in Czech Republic has been aimed at aroma and bitter hops for a long time. Recently, we have managed to get some new genotypes with a specific flavour. In 2017 Gaia and Boomerang have been released. New genotypes 5193 and 5164 have been submitted to registration process. New generation of flavour hops is typical by the wide variability of the various types of hop aroma.

Our study is focused on mutual comparison of four methods of determination of alpha acids in hops (EBC 7.4, EBC 7.5, ČSN and EBC 7.7) and their application in evaluation of hops stored under different conditions. Furthermore, the results of the comparison of predicted and actual alpha acid values in the long-term monitoring of harvesting of three Czech hop varieties are discussed. The largest differences were found between the EBC 7.5 (LCV) and EBC 7.7 (HPLC) methods; the first method gives systematically higher results and the difference exponentially increases with the hop storage index (HIS) value. The difference in HSI in fresh hops is 10 - 15%...

Though detailed analysis of malt provides information on the characteristics suitable for its processing in the brewery, the unequivocal relationship between the quality characteristics of the malt and the final, especially sensory, quality of the beer does not exist. The article summarizes the results of three-year pilot brewing tests with the barley varieties recommended for the production of beer with the protected geographical indication "Czech beer" Blanik, Bojos, Francin, Laudis 550, Malz, Petrus and Vendela and varieties for the production of export malts Kangoo, Sebastian, Sunshine and Xanadu. The results showed some specific characteristics...

Wikipedia is the most widespread, most well-known and perhaps most cited source of information today. It offers significant communication potential. It is necessary to evaluate the use of Wikipedia now and in the future. It has been found, that no facts exist about many personalities from malt- and brewing branches. It could be much more publicized about this topic from the history up to now, from public article up to expert texts. The data in language versions are often missing. The Research institute of Brewing and Malting (RIBM) started to publish articles about its important personalities and some important projects of RIBM. In addition to the...
