<p>PURPOSE:To obtain malt whisky having high content of higher alcohols, by using a heat-resistant protease agent in combination with conventional agent in the saccharification of malt to increase the amino acid content of the wort, and carrying out the fermentation using the yeast in high concentration. CONSTITUTION:The amino acid content of wort is increased by using a heat- resistant protease agent in combination with conventional agent in the saccharification of malt. The amount of the inoculated yeast is increased to >= about 10 times that of the conventional process for the brewing of whisky, and the fermentation is carried out in the presence of the yeasts in high concentration. The conversion of the amino acids to higher alcohols can be improved, and the content of the higher alcohols in the fermented product is increased. The malt whisky having high content of higher alcohols such as amyl alcohol can be obtained by this process.</p> |
