Sažetak
To ensure the demanded quality for malting barley, each season a number of quality indicators have to be determined and evaluated. Depending on the variety, location and growing conditions (precipitation, temperature, soil type, and agro- technical measures), the achieved quality indicators have to fulfil a certain theoretical value to set the variety into an end-purpose group. End purpose can be designated as feed or malting. However, based on their intended end-use and in respect to their characteristics, barley varieties in Croatia can also be classified as dual, namely malting-feed varieties. Most important parameters that have to be analyzed every year include total protein content, soluble proteins, moisture, malt extract, extract difference, friability, viscosity, Kolbach index, wort color, wort pH. For malting barley varieties, these values have to be within the set and recommended values, taken from different literature sources. The aim of this work was to present a five-year long, continuous examination of all mentioned quality control indicators. All indicators are prone to variations due to the variety, location and growing conditions, so a five-year continuous study can provide mean values for the tested indicators important for growers, maltsters and brewers. Expressed variations can be noted in protein content. Namely, 2018 resulted with the lowest protein content in comparison to other years, for almost all varieties.
