The invention discloses a production method of
flavor sparkling
wine by a traditional method, and relates to the technical field of
wine brewing, the method comprises the steps of base
wine preparation, secondary
fermentation liquor blending, secondary
fermentation in a
bottle,
ageing in the
bottle,
bottle rotating for residue removal,
sugar supplementation for
seasoning and post-treatment, the grape concentrated juice is used as a
sugar source of secondary
fermentation liquor, a specific fermentation aid is added, the
temperature and pressure of secondary fermentation in a bottle are accurately controlled,
ageing is carried out for more than or equal to 15 months, regular slight shaking is carried out, mechanical bottle rotating and automatic
slag removing are combined, and after
sugar is supplemented, low-temperature stabilization and membrane
filtration sterilization are carried out. The method has the beneficial effects that the production period is remarkably shortened on the basis of ensuring complex
flavor brought by
yeast autolysis through full-process quantitative
parameter control; bubbles are fine and lasting, and the wine
loss rate is low; manual experience dependence is reduced, and batch stability is improved; the finished product has typical
flavor and good
shelf life stability of a traditional method, and high-efficiency and high-quality production is realized.
