What is strain the wine?
The strain is the variety of species of vine that produces UVA.
Among the factors determining the quality of the wine, the variety of the strain may be easier to detect in a blind tasting.
Thus, the color of wine is determined by the grape skins: red wines can only be extracted from grapes with dark bark. Sweet dessert wines are produced from varieties of strains subject to the "noble rot" or whose fruits ripen quickly. Already sparkling wines and brandy need grapes with high natural acidity.
And the best proof of the quality of a variety of strain is its ability to produce wines with aromas and flavors identifiable, even if these have been influenced by the climate, the terroir and the type of planting.
