Today, let’s talk about the types of red wine
Red wines are classified differently according to different classification standards. There are four common classification criteria: sugar content, color, barometric pressure and alcohol content.
1、Red wine can be classified as dry, semi-dry, semi-sweet and sweet according to the sugar content.
3, according to the gas pressure can be divided into static wine and sparkling wine.
4、According to the precision of red wine, red wine can be broadly divided into ordinary red wine and fortified red wine.
I. Classification of the sugar content of red wine
First, let us understand the principle of fermentation.
Alcohol fermentation in red wine is the process by which yeast “eats” the sugar in the grapes and converts it into alcohol and carbon dioxide.
According to the sugar content, red wines can be classified as dry, semi-dry, semi-sweet and sweet.
1、If the residual sugar in red wine is less than 4g/l, you will not feel the obvious sweetness when tasting. This kind of wine is called dry red wine.
2、The amount of residual sugar in red wine is between 4g/l and 12g/l. This type of red wine is called semi-dry red wine. However, it should be noted that dry red wine and semi-dry red wine should also be classified according to the sugar to acid ratio.
3. When the residual sugar content in red wine is between 12g/l and 45g/l, the sweetness of the wine will be more pronounced. This kind of red wine is known as semi-sweet red wine.
4、When the residual sugar in red wine is greater than 45g/l, it is called sweet wine. For example, ice wine or expensive rotten red wine, they usually have the aroma of dried fruit and honey.
This issue introduces red wine can be divided into the following four types according to the sugar content: dry, semi-dry, semi-sweet and sweet. Generally speaking, in order to facilitate future customs inspections, businesses will in principle only indicate on the back label the type of red wine: dry red wine, semi-dry red wine, semi-sweet red wine, sweet red wine, but not the exact amount. Because red wine is a natural thing, different batches of red wine products may not have the same sugar content or alcohol content. However, we can know the general range of sugar content based on the type of red wine.
