What problems should be paid attention to in homemade wine?

I think in general, we should pay attention to three problems. First, we should choose pure water to make wine. Second, it is best to choose fresh grapes or raisins produced in autumn. Third, we must ensure that it is sealed and preserved, and we must not let outside air invade, which will lead to mildew.

The first reason is that pure water has a small molecular weight and can quickly penetrate into our cells. Therefore, when brewing wine, there are not so many impurities in pure water that can quickly soak grapes, or the surface of raisins can quickly dissolve their cell membranes, so that nutritional molecules can penetrate into pure water as soon as possible. We say that the faster the fermentation, the higher the purity of wine, which becomes a very important condition when selecting water. The general suggestion is to choose Wahaha mineral water, because Wahaha mineral water has been used as pure water in most scientific research laboratories, so we can choose it. The purified water in the water purifier downstairs should be three yuan a barrel, and two barrels will be enough for us to drink wine for half a year.

The second reason for choosing fresh grapes or raisins in season is to ensure the freshness of ingredients. If you want to do a good job, you must sharpen your knife first. If you want to taste good wine, you must first ensure that your ingredients are impeccable. Moreover, the grapes in this season are all skinned, which is in line with the solar terms of that year, just like Lafite in 1982. The reason why it is popular and the price is so high is that the grapes produced by French manor 1982 are the best grapes in the 1980s.

Third, we must pay attention to sealed preservation when fermenting, because the air contains a lot of bacteria, viruses and fungi, although it will not cause any harm to our human body. If he enters our sealed tank without our knowledge, all our previous efforts will be in vain, and so many good raw materials and ingredients will be wasted.
