Matters needing attention in material selection: The first step in the process of wine brewing is material selection, and choosing the right wine grapes is the first and most critical step for a successful start. It is suggested that professional wine grapes should be selected as far as possible when conditions permit. Of course, if we only brew red wine out of personal hobbies and interests, just to entertain ourselves, then there are not so many requirements for choosing grapes. Choosing professional wine grapes is to make more delicious wine. In addition, we should remind everyone that homemade grapes should not be stored for too long after they are bought, and grapes should not be stored at room temperature for too long, which is easy to mold. If the freshness is not high, it will make the wine more moldy.

Matters needing attention in stalk removal and crushing:

In the process of removing stems, crushing and canning, the storage containers used can be bottles, cans, barrels, vats or even coke bottles and mineral water bottles. Of course, it is suggested that you still use a broken glass bottle with a transparent small mouth, which is more beautiful and easier to observe. The small mouth is conducive to preventing excessive exposure to air from oxidizing the wine.

Precautions for canning:

Grapes need to be crushed before canning, which is beneficial to make the grape juice contact with the grape skin more fully and make the natural yeast on the grape skin propagate and start fermentation quickly.

When canning, the poured grape pulp shall not exceed 4/5 of the volume of the fermentation container, and a fermentation tube shall be installed. Homemade wine will produce a lot of carbon dioxide during fermentation. The installation of fermentation tube is beneficial to eliminate the generated gas. If you pour too much fruit pulp without installing a fermentor, it will easily lead to the container bursting and bring unnecessary losses.

Precautions for adding sugar:

The amount of sugar added is mainly calculated according to the alcohol content of the wine that the brewing friends finally want to brew and the sugar content of the selected wine grapes. Usually, according to 17g sugar/liter, 1 degree alcohol can be produced. Without sugar, the highest alcohol content of homemade red wine is 15 degrees. Brewers can decide how much sugar to add according to their own needs.

In addition, it should be noted that if there is too little sugar in the process of adding sugar, the alcohol content of the final wine will be very low, and too much sugar will easily lead to incomplete fermentation and sweet wine. Of course, alcohol can also be added to increase the alcohol content of the finished wine.
