You can heat it. Heating for 20 minutes before drinking can reduce the methanol in homebrew wine.
1. Home-brewed wine is a low-alcohol beverage made from fresh grapes or grape juice through fermentation. Grape fruit contains pectin, which is broken down during the brewing process to produce methanol. The amino acids in the fruit also produce methanol during metabolism. Temperature also causes the methanol content to increase during fermentation. But as long as the amount of methanol broken down in the wine meets national standards, it is not a health hazard.
2, the way to reduce the methanol in homebrewed wine: heating.
(1) Because the boiling point of methanol is close to 30 degrees Celsius, it can be heated to 30 degrees Celsius to 40 degrees Celsius, and the methanol will evaporate with such a temperature.
(2) Don't put the wine on the stove and heat it directly, then although the methanol will evaporate with the heating, it will also affect the taste because of the high temperature. It is recommended that before drinking homebrew, you can pour the wine you need to drink into a vessel, then put this vessel into a thermos cup or a thermos bucket, and then pour boiling water into the thermos cup or the thermos bucket.
(3) Boiling water is usually around 90 degrees Celsius, and it takes a process to transfer its heat to the vessel containing the wine in the thermos, an operation that actually doesn't raise the temperature of the wine very much, and doesn't affect the taste as much as direct heating does.
(4) In the operation of the wine containers and insulation cup (insulation bucket) lid are open, easy to methanol volatilization, in the 20 minutes before drinking operation is preferred.
