From the famous wine party in Hong Kong, beginners will think that the grapes used to make wine are the same as the grapes we usually eat. In fact, the raw materials for wine making are different from the grape varieties we contact every day. Wine grape is a very small fruit, because the flavor components of grape are contained in grape skin and grape seed, so grape skin and grape seed account for a high proportion in the whole grape fruit. Because of this, the taste of grapes is so rich, especially when wine grapes enter the brewing process, the sugar in grapes is converted into alcohol, and the richness of wine flavor depends on color, aroma and taste.

Moreover, our requirements for grapes are not only sweet and sour, but also a lot of pulp, so the grapes we usually eat are generally thin-skinned grapes. As can be seen from the above, due to the different uses of grapes, the distinction between raw materials is also very strict.
