Method for brewing grape flavor type white wine

The invention relates to the field of wine brewing, and relates to a method for brewing grape flavor type white wine. The method comprises the following steps: (1) carrying out peduncle removal and crushing on an amur grape, and then mixing and soaking grape juice and peel residues to extract an aromatic substance; (2) separating the grape juice from the peel residues, and carrying out vacuum heating concentration treatment on the grape juice; (3) adding an active dry yeast to the concentrated grape juice for fermentation; and (4) carrying out continuous distillation on the concentrated grape juice obtained after the fermentation is finished by utilizing a distillation tower, producing distilled wine, blending, aging, carrying out stabilizing treatment, and then filtering and packaging. According to the method, the content of nutrient substances is increased and a large quantity of aromatic substances are retained by firstly extracting the nutrient substances contained in peel through soaking, then carrying out the concentration treatment on the grape juice and then carrying out the fermentation, so that a large quantity of the nutrient substances can exist in white grape wine in a later distillation process, and the fragrance of a grape fruit and an aromatic component generated in a fermentation process are retained; the grape flavor type white wine is mellow, refreshing, aromatic and fierce in taste, is favorable to human health by containing multiple nutrient components and can be used for reducing the injury of alcohol contained in white wine on a human body.

Method for comprehensive utilization of high mountain grapes by using accompanying fungi and enzymolysis technology

The invention discloses a method for comprehensive utilization of high mountain grapes by using accompanying fungi and an enzymolysis technology. The method comprises the following steps: (1) performing domestication and amplification culture on accompanying fungi 'white ash' of high mountain grape skins in grape skin pressed liquor to obtain a mixed strain for making high mountain grape wine by fermentation; and (2) cleaning high mountain grapes, draining the high mountain grapes, then removing stems for crushing, inoculating the mixed strain, adding sucrose for fermentation at 25-35 DEG C for 5-7 days, then performing filtration when the sugar content of fermentation liquor is less than or equal to 7g/L, drying filter residues in the sun to enable skins to be used as an animal feed, performing enzymolysis after degreasing of seeds, extracting procyanidine, performing fermentation on filtrate until the sugar content is less than or equal to 4g/L, then siphoning wine liquid at upper layer, throwing away a bottom layer yeast paste, and performing fermentation continuously for 15-30 days at 15-30 DEG C to obtain dry red high mountain grape wine. According to the method disclosed by the invention, multiple technologies are effectively integrated together to achieve an optimal comprehensive utilization effect of the high mountain grapes, and according to the method, the market competitiveness is strong, and the application prospect is broad.

Ultra-low temperature preservation method and thawing method of stem segment of mountain grape and thawed stem segment of mountain grape

The invention relates to the field of agricultural technology, and provides an ultra-low temperature preservation method of a stem segment of a mountain grape and a thawing method of the stem segmentof the mountain grape preserved at ultra-low temperature. The ultra-low temperature preservation method of the stem segment of the mountain grape comprises the following steps of placing the stem segment of the mountain grape with dormant buds of 28% - 32% moisture content in a vacuum container, cooling the vacuum container with the stem segment of the mountain grape to -200 - -160 DEG C at a cooling rate of 0.2 - 0.6 DEG C / min, and placing in liquid nitrogen environment for preserve. The cryopreservation time is long and the survival rate is high. The thawing method of the stem segment of the mountain grape preserved at ultra-low temperature comprises the following steps of taking the stem segment of the mountain grape preserved by the above-mentioned preservation method from the liquidnitrogen environment and thawing it naturally at room temperature for 1.5 - 2.5 h, then soaking it in water for 22 - 26 h. The survival rate of the stem segment thawed in this method is high. The above-mentioned thawing method is used to obtain the thawed stem segment of the mountain grape after being preserved at ultra-low temperature. The survival rate of the stem segment of the mountain grapeis high.
