Many people have been loved wine throughout the years, and the world. Many stores sell various wines, and we can buy them easily; nevertheless, there are few people who have the common knowledge of making wine. The process can be divided into three parts: de-stemming and crushing, fermentation, maturation and bottling.
The first process is de-stemming and crushing. The meaning of the term de-stemming is removing the stems from the grapes. After the de-stemming process, the juice is collected. The juice that comes out from the weight of the grapes alone is called "free-run" juice. It is generally saved and fermented separately. The crushing process is a little different from region to region, but in all places, there is pressure that extracts the juice in a press. Some regions have regulations about how much juice may be taken from a given mass of grapes.
The second process is fermentation. Fermentation is a biochemical process that bacteria and yeast break down the organic compound in grape juice
