Embodiment 1
[0026] A kind of rosé wine brewing process, comprises the following steps:
[0027] Grape raw materials are selected by ears, grains, destemmed and crushed, and the crushed grape must is pumped into the freezing tank, and 35mg / L of sulfur dioxide is added according to the volume of the grape must, mixed evenly, cooled to 10°C for immersion, and separated after 10h of immersion 20wt% grape serum to fermenter;
[0028] Raise the temperature of the grape serum to 16°C, add yeast according to the mass of the grape serum at 220g / T, and then carry out alcoholic fermentation, the fermentation temperature is controlled at 16°C, and the alcoholic fermentation is terminated when the residual sugar is less than 4g / L;
[0029] Transfer the alcohol-fermented wine into a malolactic acid fermentation tank, raise the temperature to 18°C, add 10g / T of lactic acid bacteria, and when the malic acid content drops to zero, add 50㎎ / L of sulfur dioxide to stop the fermentation and obtain raw wine; ...
Embodiment 2
[0041] A kind of rosé wine brewing process, comprises the following steps:
[0042] Grape raw materials are selected by ears, grains, destemmed and crushed, pump the crushed grape must into the freezing tank, add 38mg / L sulfur dioxide according to the volume of the grape must, mix well, cool down to 11°C for soaking, and separate after soaking for 10 hours 20wt% grape serum to fermenter;
[0043] Raise the temperature of the grape serum to 16°C, add yeast according to the mass of the grape serum at 210g / T, and then carry out alcoholic fermentation, the fermentation temperature is controlled at 16°C, and the alcoholic fermentation is terminated when the residual sugar is <4g / L;
[0044] Transfer the alcohol-fermented wine into a malolactic acid fermentation tank, raise the temperature to 19°C, add 10g / T of lactic acid bacteria, and when the malic acid content drops to zero, add 50㎎ / L of sulfur dioxide to stop the fermentation and obtain raw wine;
[0045] The raw wine is aged,...
Embodiment 3
[0056] A kind of rosé wine brewing process, comprises the following steps:
[0057] Grape raw materials are selected by ears, grains, destemmed and crushed, and the crushed grape must is pumped into the freezing tank, and 30 mg / L sulfur dioxide is added according to the volume of the grape must, mixed evenly, and the temperature is lowered to 13°C for immersion, separated after 8 hours of immersion 15wt% grape serum to fermenter;
[0058] Raise the temperature of the grape serum to 18°C, add yeast according to the mass of the grape serum at 200g / T, and then carry out alcoholic fermentation, the fermentation temperature is controlled at 17°C, and the alcoholic fermentation is terminated when the residual sugar is less than 4g / L;
[0059] Transfer the alcohol-fermented wine into a malolactic acid fermentation tank, raise the temperature to 19°C, add 10g / T of lactic acid bacteria, and when the malic acid content drops to zero, add 50㎎ / L of sulfur dioxide to stop the fermentation ...
