Study of the technological properties of the historical barley variety Proskovcuv hanacky

Popis výsledku v původním jazyce

Breweries currently face challenges in the development of new products such as “beer with a story”. The historical variety of barley Proskovcuv hanacky belongs among the famous and undoubtedly important varieties of Czech malting barley. For its excellent qualities, this variety has been widely used in breeding and today it is the basis of the pedigree of many modern European varieties. The aim of this work was to describe the technological, analytical and sensory properties of malt and beer made of this variety and to evaluate its potential for current beer production. Pilsner-type malt made in a fl oor malt house was characterized by high protein content (13.9%) and very low cytolytic, proteolytic and amylolytic modifi cation. Beer was made from the malt in two small reweries using a two-mash decoction process and Saaz hops. The beers were lowly fermented (apparent attenuation 67 and 69%) and had a high content of dextrins, beta-glucans, arabinoxylans and olyphenols. Sensory evaluation of the beers was similar to current conventional lager-type beers. The study has shown that Proskovcuv hanacky barley, together with traditional malting and brewing technology, could represent, for example, an interesting diversifi cation of the range within the limited productions of smaller breweries.
