Abstract: Stale flavor formation in beer is reduced by contracting malt, prior to extracting to produce wort, with a primary or secondary mono- or polyhydric alcohol or with acetic acid or with dimethylsulfoxide to reduce the amount of precursors of 2-trans-nonenal present in the malt.
Abstract: Wort suitable for making e.g. beer is produced by extracting ground chit malt with a mixture of hot water and malt, the proportion of malt being 10 to 40% by weight on a solids basis of the dry weight of the mixture of ground chit malt and malt.
