Why is wine divided into red wine and white wine?
The division of red wine and white wine mainly rests with the
difference of grape varieties and brewing techniques. Processing techniques of
red wine mainly features fermentation with skin, by which the pigment and
polyphenols can be fully extracted from grape skin. During red wine brewing, skin
residue can be segregated only after primary fermentation, and red wine base
will be obtained; then bright-colored and delicious red wine will be done after
post-fermentation, storage and other processing techniques. However, processing
techniques of white wine mainly characterizes separation of skin and juice. White
wine is brewed by fermented pure grape juice after fresh grape squeezing and
separation.
