Grape wine luminous cup, if you want to drink pipa, you may not feel unfamiliar with wine, is it just wine made from grapes. In fact, this is not accurate. According to my country’s latest wine standard GB15037-2006, Wine is fermented wine with a certain degree of alcohol, which is made from fresh grapes or grape juice through full or partial fermentation.

There are many and complex wine types, and the classification standards are extremely strict. According to the color classification, it is divided into red wine, rosé wine and white wine. This classification is based on the body color, which is easy to understand.

Red wine is mainly made from grape varieties with purple-black skins and fermented with grape skins and juice. The body of the wine is mainly purple, deep red and ruby ​​red. Its color mainly comes from the anthocyanin in grape skin, a common water-soluble plant pigment. Grape skin contains polyphenols such as catechins and resveratrol, which have anti-aging effects. As the grape skins are contained in the fermentation process, red wine generally has higher health value than white wine. The main brewing varieties are Cabernet Sauvignon (Cabernet Sauvignon, also known as Cabernet Sauvignon), Cabernet Franc (Cabernet Franc), Shiraz (Syrah in France), Pinot Noir (Pinot Noir) and so on.

rosé wine, also known as rosé or pink wine, is made from colored red grapes with skin fermentation or separate fermentation. The body of the wine is pink, pale rose, and light red, which is lighter than red wine. It is a small ethnic group between red wine and white wine. The brewing varieties are mainly black grapes and red grapes.

white wine is mainly made from grape varieties with no color in the flesh, and its skin may be purple-black or yellow-green. The wine is mainly golden yellow, straw yellow, light yellow and even almost colorless. The reason why the color is so light is that the grape juice is separated from the grape skin immediately after being squeezed out, so that the pigment in the skin does not penetrate into the grape juice. The main brewed varieties are Chardonnay,

Gewurztraminer, Muscat, Riesling, Pinot Blanc, etc.
