Problems solved by technology

Because the typical flavor and nutritional components of lychee are significantly different from other fruits, the flavor is unstable during processing, which seriously affects the quality of lychee wine
Lychee wine generally uses lychee pulp as raw material, and its finished product color is light yellow to golden yellow, and cannot produce other hues such as red, resulting in a single appearance and quality of the product, and the taste is relatively thin and the structure is not strong.
Although the prior art fermentation with shells can improve the color of the product and produce a red hue, as the alcohol content increases, a large amount of bitter substances in the fruit shell will be leached into the wine, making the wine very bitter and reducing the quality of the lychee wine. quality

Abstract

The invention discloses a brewing method of a litchi full-fermented wine. The method comprises the following steps: (1) directly pulping litchi fruits with shells and cores; (2) adjusting the pH value of litchi pulp, inoculating a yeast for fermentation for 3-5d to obtain a first wine; (2) clarifying the first wine, adjusting the pH value of the clarified liquid, adjusting the sugar degree to be 16-18%, inoculating the yeast, fermenting at 15-20 DEG C for 2-4d to obtain second wine; (4) clarifying the second wine, adjusting the pH value of the clarified liquid to be 4.0-5.0, adjusting the sugar degree to be 16-18%, inoculating an active dry yeast which is 0.01-0.02% of weight of the clarified liquid, fermenting at 15-20 DEG C for 6-8d to obtain a third wine; and (5) centrifugally filtering the third wine, and ageing to obtain the litchi wine. The litchi wine brewed by the method is attractive pale red in color and luster and free of a bitter taste.

Description

technical field [0001] The invention belongs to the technical field of fruit wine brewing, and in particular relates to a brewing method of fully fermented lychee wine. Background technique [0002] Litchi is a unique fruit in southern my country. It has soft flesh, high sugar content, appropriate amount of organic acids and various amino acids, high nutritional value and unique flavor. It is known as a treasure among fruits. The lychee wine brewed at low temperature has unique flavor and rich nutrition, and is deeply loved by people. Because the typical flavor and nutritional components of lychee are significantly different from other fruits, the flavor is unstable during processing, which seriously affects the quality of lychee wine. Lychee wine generally uses lychee pulp as raw material, and its finished product color is light yellow to golden yellow, and cannot produce other hues such as red, resulting in a single appearance and quality of the product, and the taste is ...
