There is no need to add white wine to wine. Generally speaking, the wine yield of homemade grapes is about 50%, and 5 kg for 10 kg of grapes. If you add 2 kg of sugar, you can get about 70%, which means you can make about 6-8 kg.

The juice yield of different varieties of grapes is also different. For a handful, Kyoho is about 85%, Cabernet Sauvignon is about 70%, Beida is about 75%, and Vitis amurensis is about 60%.

Matters needing attention in wine

1, drink red wine a quarter of an hour in advance, use a special red wine bottle opener, and pay attention to the correct way to open the red wine bottle cap. Put it in it temporarily, and then wait for the oxygen in the air to oxidize the red wine so that the ingredients in the red wine can play a role.

2. Drink red wine with a glass. Due to the temperature of the palm holding the cup, the heat of the palm will be transferred to the red wine through the cup, thus causing the red wine to lose its own nutrition and efficacy.
