Malting quality indicators of Croatian dual-purpose barley varieties

Abstract

Malting barley varieties usually demand higher expences than feed varieties, at least as far as management practice is concerned. For this reason, many growers in Croatia search for a quality replacement of malting varieties. Croatian market allows dual-purpose varieties, but strict quality parameters have to be met in order for a variety to be recognized as a malting/feed variety. The aim of this research was to preliminary assess the malting quality of several malting, feed and multipurpose (dual or combined) malting/feed barley varieties. 11 barley varieties were grown in Osijek area during 2011: seven malting/feed (M/F), two malting (M) and two feed barley varieties (F). The suitability for the beer production was assessed according to the malting quality indicators, determined by using standard methods of analytica EBC (European Brewing Convention). As expected, both malting varieties (Vanessa and Tiffany) demonstrated the best malting quality parameters. Most of the combined malting/feed varieties were within recommended values, except Maxim, Lukas and Gazda, which showed the lowest results in friability. Considering that the results were collected and evaluated over a period of one year, this study was taken as a good pointer to future, longer lasting investigations.
