Title:
METHOD OF IMPROVING FERMENTABILITY OF EARLY FLOCCULATING MALT
Document Type and Number:
WIPO Patent Application WO/2008/053603
Kind Code:
A1
Abstract:
It is intended to provide a method for ensuring healthy fermentation using a yeast and the production of beer or low-malt beer having a rich flavor which comprises, in the case of producing beer or low-malt beer with the use of an early flocculating malt (i.e., a malt having an early flocculating factor of yeast), improving the fermentability of the early flocculating malt. In producing beer or low-malt beer with the use of the early flocculating malt, tannic acid is added to the wort and/or yeast to be used in the fermentation followed by the treatment with the tannic acid to thereby improve the fermentability of the early flocculating malt. To improve the fermentability of the early flocculating malt in the process of producing beer or low-malt beer, tannic acid is added to the wort before adding the yeast, the fermented wort after adding the yeast or the yeast to be added to the wort and then the treatment is conducted. Preferable examples of the tannic acid to be used in the above process include gallotannin, tara tannin, gallic acid tannin (hydrolyzed tannin) and persimmon tannin (condensed tannin).
