methanol reduction method:
1. Adding high-purity yeast: Brewed wine is made by natural fermentation. Therefore, in the air or in containers, too many bacteria and microorganisms will produce more methanol and fusel oil. Adding yeast can prevent the propagation of rotten bacteria and reduce the methanol content.
2. Choose fresh grapes: because the grapes are sprayed with pesticides during their growth. Therefore, you must wash the grapes when you brew your own wine. Also, choose fresh grapes. Some people deliberately do not clean it, saying that it is fermented for epidermal microorganisms. It is not advisable to do so.
3. Keep the container clean and hygienic: It is very important to choose what container to hold wine. In the process of brewing, many containers are used. And the most important of these containers is the fermenter. It can be fermented in containers such as glass and ceramics, which is safe and reliable. Please be careful not to use stainless steel or iron containers as fermentation containers, otherwise it is likely to cause poison.
4. Ensure hygiene and cleanliness: If the grapes are infected by bacteria in this process, they are likely to rot. The fermenter is not cleaned, and the container is not clean when stirring, which will cause bacterial infection. At this time, everyone must pay special attention. When brewing, you must ensure the hygiene of containers and hands. No water, no oil, the best effect.
5. Temperature control: If the temperature is too high, it will lead to the mutation of enzymes and other factors, and it will also produce toxic substances.
6, not easy to drink too much: when drinking homemade wine, don't drink too much. Especially the newly brewed wine, try to drink a little first. If you feel unwell, you should go to the hospital for examination in time.
