1. Edible taste

Wine grapes have small berries, thick skin, less pulp, more juice, and grape seeds (wine grapes must have a high juice yield and must be in 70 or above), it tastes a bit bitter and is basically not suitable for consumption. Our usual table grapes focus on large seeds, thin skins, and sweetness. It is best not to have grape seeds, which makes eating easier.

2. Skin color

We will find it interesting if we study these unique properties of wine grape varieties. The magnificent and attractive color of red wine comes from the skins of flat grapes. There is a special step in the red wine brewing process which is to soak the grape skins with grape juice to extract the natural pigments. The skin is dark and therefore rich in beautiful natural pigments, so the red grapes used for winemaking are often darker than the red table grapes. Some friends say that the grapes used for winemaking are "black grapes" and not red grapes.

3. Sugar and acidity

Usually, the sugar and acidity of wine grapes are quite high (the sugar content of wine grapes can reach 200g/L, and the acid content is 6-9g/L). L;), so the alcohol concentration of the produced wine will exceed 12 and the acidity (PH value) will be lower than 3.6, thus preventing the wine from being spoiled by bacteria. The tannins rich in red wine come from the peel and seeds and are natural preservatives. The tannins in red wine taste bitter and need to be paired with lower acidity, otherwise it will be difficult to drink. This means the more tannins, the lower the acidity.

The taste of general table grapes is more vegetable-like. Usually there is less sugar, and the resulting wine has an alcohol content of only 8 to 9 and low acidity. Therefore, when making home-made wine from table grapes, additional acidity or sugar must be added. Sugar is fermented to produce carbon dioxide and alcohol. Alcohol is the most powerful preservative, so the wine must reach a certain alcohol concentration to prevent spoilage. If the acidity is too low, bacteria will easily breed after contact with the air, and the wine will gradually turn into vinegar.

4. Yield

The yield of wine grapes must be deliberately reduced when planting so that each fruit can fully absorb minerals and emit a unique flavor, while the production of table grapes The more the better, and there is no need to emphasize its characteristics.

5. The taste of wine produced

Because wine grapes have different tastes, aromas, and characteristics, different varieties of grapes can be used to produce wines with different flavors. When tasting wine, if you are familiar with the special taste of each grape variety, and you can identify the grape variety based on the smell during blind tasting, this proves that the characteristics of various wine grapes are indeed unique. Wine made from table grapes does not have these characteristics.

However, whether it is wine made from table grapes or brewed grapes, it is still recommended that after opening the bottle, you should drink the unfinished wine seal. It is best to store it in the refrigerator and try to finish drinking it within a week, or change it to a small bottle to reduce contact with air.
