Making wine is done in the same way as wine, which includes making wine from raisins. Reprinted an article for reference.

●Step 1: Buy Grapes

When shopping for grapes, pick some ripe grapes, it doesn't matter if they're just a single loose grape. These grapes are easy to ferment for one thing, and the price point is relatively low for another. Commonly, grapes, raisins and marmite are used to make wine.

●Step 2: Wash the grapes

Since the skin of the grapes is likely to have pesticide residues, the cleaning of the grapes is quite important, and it's best to be able to wash them one by one, and then rinse them again and again with tap water, as well as removing the rotten grapes. Some people like to remove the skin of the grapes after the wine, which is not bad, but less some of the unique nutrients of the skin of the grapes.

●The third step: dry the grapes

Put the grapes in a watertight container and wait until the grapes are free of water droplets before pouring them into the wine jar.

●Step 4: Choose a container

The wine jar can be a ceramic jar or a glass bottle, but plastic containers are not recommended because plastic is likely to have a chemical reaction with alcohol and produce some toxic substances that are harmful to human health.

● Step 5: pinch the grapes and put them into the container

After washing your hands, pinch the grapes directly, the operation is to grab a handful of grapes to make a strong grip, and then put them into the wine altar, and then put the sugar on top of the grapes, and the ratio of grapes and sugar is 10:3, that is, 10 pounds of grapes to put 3 pounds of sugar (for those who don't like to eat sweetness, you can put 2 pounds of sugar, but you can't do without the sugar, since sugar is the grape's fermentation (important factor).

●Step 6: Seal and store

Seal the wine jar. If it's a ceramic jar, you can go to a store that buys yellow wine and order some wine clay, add water, and then paste it to seal the jar. After sealing, keep the jar in a cool place and don't turn it over or open the lid.

●Step 7: Unsealing

When it's hot, it takes about 20 days to a month for the grapes to ferment, and about 40 days for the wine to ferment now. After unsealing, fish out the grape skins floating on top, and you can drink the wine directly. Note that if you prefer a stronger wine, just delay the opening time. After opening the jar, don't forget to put the lid back on every time you ladle out the wine, so that the flavor of the wine doesn't evaporate.

The above is reproduced, roughly, but there are different opinions for your reference:

1, the grapes do not need to be overly rinsed, because the yeast needed for fermentation, from the wild yeast on the skin of the grapes, overly rinsed will be a large reduction in the amount of yeast, not conducive to fermentation.

2, the early stage of fermentation, do not seal the lid very tightly, because this is the time when the yeast reproduction, need oxygen;

3, when the fermentation is strong, you need to open the lid, because the fermentation process produces gas, too tightly sealed, it will be propped up containers, covered with a few layers of diluted cloth can be.
