Description

Rose fragrance low alcohol bubbling white grape wine and making method thereof

(1) technical field:

The invention belongs to grape drinks and making method thereof, particularly a kind of rose fragrance low alcohol bubbling white grape wine and making method thereof.

(2) background technology:

At present, grape wine is of a great variety on the market, taste abundant, but the alcoholic strength of common Sparkling wine is all about 12%, higher some specific groups that limited of ethanol content drink vinous, are that the low alcohol bubbling white grape wine that raw material is brewageed can satisfy more consumer demands with the muscat grape therefore.

(3) summary of the invention:

The objective of the invention is to invent a kind of rose fragrance low alcohol bubbling white grape wine and making method thereof, fill up China and play blank on alveolitoid grape wine kind and the making method.

Technical scheme of the present invention: a kind of rose fragrance low alcohol bubbling white grape wine, it is characterized in that said grape material adopts muscat grape, its pol is not less than 160g/L; The said physical and chemical index that makes wine is: alcoholic strength is 3-7%V/V, and reducing sugar is not less than 50g/L, and total acid is 6-8g/L, Free sulfur dioxide is not higher than 50mg/L, and Total sulfur dioxide is not higher than 100mg/L, and pressure is not less than 0.25 (MPa, 20 ℃), volatile acid is not higher than 0.7g/L.

A kind of making method of rose fragrance low alcohol bubbling white grape wine is characterized in that it is made of following operation:

(1) with the muscat grape be raw material, its sorting quality requires to be anosis fruit, mould decayed fruit, assorted fruit, requires to gather to forbid no pesticidal contamination fruit, neat, the fully matured of fruit ear of spraying insecticide the previous moon pol 〉=16 °;

(2) squeezing, up-to-standard grape is pressed extracting juice after entering factory as early as possible, and expressing process should be finished in 2 hours 30 minutes, and to reduce the duration of contact of Sucus Vitis viniferae and skin slag, Sucus Vitis viniferae is input in the nature settling tank by pipe special after the cool-heat-exchanger cooling again;

(3) clarification naturally: the sulfurous acid with food grade concentration 6% when Sucus Vitis viniferae is gone into jar is adjusted into 30mg/L～40mg/L with content of sulfur dioxide; Temperature control 12-16 ℃, separate according to clarifying effect in good time, isolated Sucus Vitis viniferae enters the polygalacturonase settling tank;

(4) polygalacturonase clarification: temperature control adds the special-purpose polygalacturonase of import grape wine at 12-16 ℃, and the polygalacturonase dosage is 1-2g/HL, separates according to clarifying effect in good time, and isolated Sucus Vitis viniferae enters withstand voltage fermentor tank;

(5) fermentation: use the fermentation of import grape wine special yeast, inoculum of dry yeast is 10-20g/HL, temperature controlled fermentation in autoclave, when alcoholic strength reaches 4-5%v/v, pressure reaches more than the 0.25M, is cooled to below 10 ℃, Free sulfur dioxide transfers to 30-50mg/L and stop fermentation, leaves standstill 7～10 days;

(6) ageing: the former wine of fermentation ends, constant temperature is below 15 ℃, and stir 1-3 every day, tastes once weekly, until reaching EnologistWinemaker's specification of quality;

(7) clarifying treatment: quantitatively add bentonite 0.5-1.0g/L really by test, left standstill 7-10 days, treat that after the clarification of wine body be that available diatomite filter filters;

(8) freezing treatment: undertaken freezingly by the temperature of 0.5-1.0 degree on the freezing point, be incubated and filter after 5-7 days;

(9) can and packing: detect wine body clarity and stability before the can, adjust free SO ₂Be 30-40mg/L, after Sterile Filtration, can and packing warehouse-in.

Superiority of the present invention is: 1, the rose fragrance low alcohol bubbling white grape wine of brewageing with muscat grape is the nutritious and healthy drink of a kind of alveolitoid low-alcoholic; 2, the making method of rose fragrance low alcohol bubbling white grape wine breaks a outmoded practice, and belongs to initiative at home; 3, the finished product of brew has the fruital of typical muscat grape, strong aroma, graceful light yellow, moderately sour and sweet, and the wine body is plump, the foam exquisiteness, tool kills a mouthful power.
