Pineapples can be used to make wine. The specific methods are as follows: First, select pineapples with higher maturity, high juice yield, and moderate acidity. In addition, the pineapples must be of high quality and free of insects and mildew.
Second, peel and wash the pineapple, then use a single-pass beater to crush the pineapple and squeeze the juice.
Third, adjust the acidity of pineapple juice to between 0.8 and 1.0. Then, keep the fermentation temperature between 20°C and 24°C, and the number of fermentation days is about a week.
Fourth, after fermentation, remove the excess residue at the bottom of the barrel, and then continue fermentation. This fermentation time will be at least one month.
Fifth, aging, during the aging process, it is best to carry out cold treatment, which can remove some unnecessary impurities and make the wine more transparent and clear.
Sixth, it takes three months to blend and store pineapples. After that, different batches of wine are blended to make the wine meet the standards of pineapple wine. If the brewed wine is not sweet enough , you can add some sugar in an appropriate amount to make the wine taste more delicious.
