Production method of grape wine

Abstract

The invention discloses a production method of grape wine. The method comprises the following steps of collecting ripen grapes; eliminating stems; milling and crushing the cleanly washed grapes to obtain grape juice raw liquid; meanwhile, pumping the grape juice raw liquid into a storage tank; adding white granulated sugar into the grape juice raw liquid subjected to low-temperature soaking so that the sweet degree is improved to the required value. The prepared grape wine is filtered by a diatomite filter; the alcoholic strength is integrally reduced; meanwhile, bitter and astringent substances generated in the fermentation process are also absorbed, so that the overall mouthfeel is softer; two kinds of sterilization methods including a film filtering method and a pasteurization method are used; the remained yeasts are effectively eliminated; therefore the deterioration fermentation condition generated in the subsequent storage process can be avoided; a product can be stored for a longer time under the condition of no additives; in addition, auxiliary materials of traditional Chinese medicine ingredients and auxiliary materials with different tastes are added, so that the grape wine has different flavors; the overall applicable people groups are wider.

Description

technical field [0001] The invention relates to the field of wine production, in particular to a wine production method.
