Grape wine brewing method with oak pieces

Abstract

The invention discloses a grape wine brewing method with oak pieces. The grape wine brewing method comprises the following steps: I, preparing oak pieces from waste oak buckets after wine storage; II,preparing fruit pulp from fresh organic wine brewing grapes, pumping the fruit pulp into an alcohol fermentation tank, adding the oak pieces at an amount of each kilogram of the fruit pulp corresponding to 2.5g of the oak pieces, uniformly mixing with the fruit pulp, and performing temperature controlled fermentation; after fermentation is completed, standing for 10 days, filtering, and taking out the oak pieces; III, putting new organic grape wine obtained through fermentation into a newly purchased oak bucket which is cleaned and sterilized, soaking other oak pieces for 30 minutes with 75%alcohol, draining off the water, soaking by adding 3g of the alcohol per kilogram of grape wine, threading the oak pieces with a small line, suspending in the oak bucket, sealing the oak bucket, storing the oak bucket for 1.5 years or greater at a constant temperature and constant humidity without noise, taking out, and putting wine into bottles. Due to the adoption of the oak pieces, plateau organic grape wine can be stable in wine color, the fragrance of the wine can be improved, and the texture property of the wine can be improved.

Description

technical field [0001] The invention relates to a wine brewing method, in particular to a wine brewing method adding oak chips, and belongs to the technical field of wine brewing. Background technique [0002] In the long history of wine, the role of oak barrels has been increasingly recognized and valued. Historically, oak barrels were primarily used for storing and transporting goods, and today they are almost exclusively used for aging fine wines and brandies. The best wines in the world are brewed in oak barrels. During the brewing process, some chemical changes will occur between the wine and the oak barrels, making the wine more complex in flavor and better in quality. [0003] But, as far as the present is concerned, there are some defects in the method that the original oak barrel is only used for the storage of wine link: the use of oak barrel in the link of wine storage, although it can make the three types of tannin, resin and sugar, and lignin aromatic component...

Problems solved by technology

[0003] But, as far as the present is concerned, there are some defects in the method that the original oak barrel is only used for the storage of wine link: the use of oak barrel in the link of wine storage, although it can make the three types of tannin, resin and sugar, and lignin aromatic components in the oak barrel Substances dissolve in wine, but only the three types of substances in the 1-3mm wood layer of the inner barrel dissolve in wine, and the oak barrels are discarded after wine storage, resulting in a large amount of unimpregnated oak waste, because oak barrels need 80 years The production of old oak trees destroys precious oak plant resources and affects and destroys the ecological environment

Although this method can reuse oak barrels to a certain extent, it still has the defects of insufficient utilization, difficulty in re-toasting, and high loss rate.
