A kind of fermenting method of continued grains of rice wine

Abstract

The invention relates to a rice wine grain stillage refilling fermentation method. The rice wine grain stillage refilling fermentation method comprises the steps of soaking of raw material rice, rice steaming, distiller yeast mixing, saccharification, fermentation, wine distillation and the like. The rice wine grain stillage refilling fermentation method greatly improves the content of flavor and fragrance components such as of total acid, total ester, ethyl lactate and beta-phenethyl alcohol.

Description

technical field

[0001] The invention relates to a fermentation method for continued grains of rice wine, which belongs to the technical field of wine making. Background technique

[0002] At present, the fermentation process of rice wine all adopts the semi-solid-state fermentation process of solid-state saccharification and liquid-state fermentation. After each fermentation, all distiller's grains (distiller's grains) are steamed.

[0003] 1. The fermentation time is short (7-10 days);

[0004] 2. The fermentation process is simple (single-batch independent fermentation);

[0005] 3. The number and variety of wine-making microorganisms are less, and the fermentation metabolites are less.

[0006] Due to the above reasons, the content of rice wine flavor and aroma substances (total acid, total ester, ethyl lactate, β-phenylethyl alcohol, etc.) is low, which seriously affects the mouthfeel and quality of rice wine. Contents of the invention
