Production of beer using native and hydrothermically treated barley (extruded barley flakes) as malt substitute was examined in this work. Nine samples of beer were produced on a laboratory scale, and malt was substituted (10–40%) by native barley flour or hydrothermically treated barley. Infusion mashing was employed, and native barley flour was pretreated by cooking. Worts were boiled with 150 g/hl native hops for one hour. Saccharomyces uvarum strain 112 was used for the fermentation, at 8°C, for 10 days. The results showed that the fermentation was normal in all samples. The use of hydrothermically treated barley in beer production produced beers, similar to those made with native barley as malt substitute, minimising the time needed for beer production and maximising the capacity of the brewhouse.
