Wine production method of fermentation 48 hours later to see if the fermentation is good (the water level rises or the phenomenon of bubbling)
Wine production method of filtration first stainless steel mesh filtration, and then filtered with 2 layers of gauze, to ensure that the filtered liquid is clear, it is best to filter the liquid more than three times, the interval between each filtration of a day or so
Wine production method of Fermentation will be filtered after the residue squeeze dry after weighing out and a few pounds, with good sugar and tunes, fermentation again. Repeat step 3 for the fermented liquid.
The method of making wine is to seal the filtered liquid in ceramic or earthenware jars, add white wine and seal it well.
Use fresh grapes. It is best to buy grapes when they are in abundance, such as August and September, and October is already a little late. Don't buy early market trellis fruit, the price is expensive, not to mention the taste is not good. The best thing to do is to buy large purple grapes. Wash and pick the grapes one by one, drain and dry them (this is very important.). I've bought discrete grapes that were sold cheaply by grape sellers just before closing time, and they were ripe enough to save me from having to pick them one by one.
Preparing regular sugar. The ratio of grapes to sugar: 10:2.
Prepare glass jars, or small oak wine barrels or wine jars.
Pour the dried grapes into the prepared vessel and put it flat. Spread the sugar directly on top of the grapes. The grapes do not need to be specially squeezed. Put water in the groove at the mouth of the altar and close the lid. Leave about 1/3 of the space in the altar.
Wait for the grapes to ferment. In August and September, it takes about 20 days. Cold weather takes longer. If the weather is very cold, the fermentation will be incomplete, and the wine will be low in volume and bad in flavor. During the fermentation process, you can see the grape juice gradually precipitate out, the more diffuse and higher; you can hear the sound of bubbles, the more powerful the fermentation, the more bubbles. When the fermentation is complete, the bubbles are basically gone. At this point, the wine has basically flooded the grapes.
When pouring the wine out, squeeze the grapes in the altar with a prepared clean gauze until all the liquid is extracted. The wine should be placed in a glass vessel, never a plastic one, or the wine will smell like plastic inside and be all bad.
The wine settles for two or three days and is ready to drink. It's not very sweet, the wine tastes sweet, and the wine is reddish in color. The sugar is converted to alcohol through "desugarization" (which is said to be a term used in the brewing industry).
