Problems solved by technology

No wild grapes are used as raw materials to brew sparkling wine, and there are many problems in the secondary fermentation, such as: long production cycle, complicated production process, high cost, poor quality control, etc.
The single variety limits the diversity of sparkling wine, and the secondary fermentation in the bottle brings certain difficulties to the production and quality control of sparkling wine

Embodiment Construction

[0019] The present invention directly squeezes the fruit of the wild grape, ferments the clear juice with alcohol, and retains the gas in the later stage of fermentation to obtain the sparkling wine of the wild grape. The specific implementation steps are as follows:

[0020] (1) For the first time, wild grapes were used as raw materials for sparkling wine. Raw material maturity control: measure the reducing sugar and total acid of the raw material, and harvest manually when the optimal maturity (sugar-acid ratio is equal to or greater than 20) is reached.

[0021] (2) Harvesting: When harvesting, try to keep the fruit intact and not damaged.

[0022] (3) Sorting of raw materials: select fruits with good maturity and no green or diseased fruits.

[0023] (4) Squeeze to extract juice: directly squeeze without destemming and crushing. When pressing, control the juice yield at 50%, and clarify at low temperature after pressing to prevent the oxidation of the grape juice and en...

Abstract

The invention relates to a manufacturing method of wine, in particular to a manufacturing method of wild downy grape sparkling wine. The wild downy grape sparkling wine manufactured through the method maintains aroma characteristics of wild downy grape fruits, the shortcomings of rough taste and bitter after-taste of the wild downy grape fruits are overcome, natural nutritional value of the wild downy grape fruits is maintained, carbon dioxide gas generated by fermenting sugar of the wild downy grape fruits is maintained, damage to fruit wine taste caused by manually added carbon dioxide is avoided, and a brewing process is simplified. The manufacturing method comprises the following operating steps: (1) adopting Chinese wild downy grapes to serve as a raw material of the sparkling wine, and controlling raw material maturity; (2) harvesting and separating the downy grapes; (3) directly pressing the downy grapes to extract juice; (4) clearing the juice at low temperature; (5) performing alcoholic fermentation; (6) performing tank switching; (7) ending fermentation; (8) performing refrigeration ageing; and (9) performing equipressure filtering and filling.

Description

1. Technical field: [0001] The invention relates to a method for producing wine, in particular to a method for producing sparkling wine from wild hairy grapes. 2. Background technology : [0002] The raw materials used for wild hairy grape sparkling wine are wild hairy grapes from Qinling Mountains, Shaanxi, China and Yunxi, Hubei Province. (Vitis quinquangularis Rehd.) And other wild grape berries. Qinling in Shaanxi and Yunxi in Hubei are rich in wild grape grape resources, and the growing environment is pollution-free. High nutritional value, containing a variety of amino acids, vitamins, trace elements, and polyphenols. It has strong anti-oxidation and can play a variety of functions such as beauty and health care. Therefore, it is necessary to develop high value-added products according to the characteristics of wild grapes, so that the abundant wild grape resources can be well protected and utilized. [0003] Sparkling wine is a very popular wine in the internat...
