Problems solved by technology

[0002] At present, the rosé wine brewing technology all adopts the preparation process of malolactic fermentation; however, the wine produced by this process lacks refreshing taste and pleasant aroma, and the wine process takes a long time. The maceration time of the wine is about 36 hours, so the preparation cost is relatively high
In addition, the skin soaking temperature of the existing technology is generally 20°C, and the fermentation temperature is 18-20°C. During the fermentation process, more fusel alcohols are produced, and the aroma is prone to defects.

Embodiment Construction

[0016] The raw material Zengfande grape used in the rosé wine of the present invention is introduced from France, and is planted at the Great Wall Sanggan Winery in Shacheng, a famous grape producing area in China. Its preparation process is as follows:

[0017] a. Select Zinfandel grapes with a sugar content of 161-181g / L for picking, secondary sorting, destemming and crushing;

[0018] b. Add sulfur dioxide 40-60mg / L when Zengfangde grapes are destemmed and crushed to prevent raw materials from being oxidized, sterilized, and ensure pure yeast fermentation;

[0019] c. The pectinase low-temperature impregnation process is to add pectinase 15-20g / ton for clarification;

[0020] d. Dipping and improving color at a low temperature of 13.5°C for 26.5 hours;

[0021] e. Add French active dry yeast 2g / L, and ferment at a temperature of 16.5;

[0022] f. When the sugar content of fermentation reaches 45g / l, within 24 hours, carry out 4 times of high-speed separation at even in...

Abstract

The invention relates to the technical field of wine brewing, in particular to a preparation method of Zinfandel pink wine. At present, according to the pink wine brewing technique, the preparation technique of malo-lactic fermentation is adopted, and the wine produced by the technique is lack of refreshing taste and pleasant fragrance. In addition, the skin soaking time of pink wine is about 36 h in general, the skin soaking temperature is 20 DEG C in general, and the fermentation temperature is 18-20 DEG C. Not only is energy wasted, but also the technological process is long. According to the preparation method of Zinfandel pink wine, soaking for 26.5 h to brighten color is carried out at the low temperature of 13.5 DEG C, alcoholic fermentation is carried out at the temperature of 16.5 DEG C, and the procedure of malo-lactic fermentation is omitted. The product wine has refreshing taste and pleasant fragrance.
