Abstract

Barley is considered as the potential substrate for beer production but in tropical countries, barley needs to be imported from temperate countries. Hence, there is a need to search for alternate substrates to meet the increasing demand of beer and to reduce its cost. In the present work, fifteen varieties of sweet sorghum grains were evaluated for their potential of beer production. Beer was produced using sweet sorghum and pilsner malt blend in the ratio of 40:60 respectively. Two Saccharomyces cerevisiae strains, GP4 isolated from traditional fermented beverage (Gudanji) of North-Western Himalayas (Bharmour region) and MTCC 11815 were compared for their fermentative capability of wort. Out of all the sweet sorghum varieties assessed, beer made from CSV 24SS using S. cerevisiae (GP4) had highest alcohol content of 5.8% (v/v) and the highest sensorial acceptance. The CSV 24SS variety was then used for upscaled production (20 litres) of beer using indigenous GP4 yeast tstrain. The beer produced was pale gold in colour and had a pH of 4.2 and titrable acidity of 0.36%. The beer was evaluated by a panel of judges for its sensorial profile and received a mean score of 7.8 out of 9 on the Hedonic scale, which indicates its consumer acceptance same as that of commercial malt beer.
