Wine is an alcoholic beverage, typically made of fermented grape juice. Wine is primarily categorized by color: red and white.
It is the grapeskins that are responsible for the red wine’s distinct color spectrum. The skins are in contact with the grape’s juice during the fermentation process, allowing the dispersion of both color and tannins. The individual wine’s particular red hue depends on the grape type used in the process and the length of time the skin’s pigmentation is in contact with juice.
Port wine is wine originated in Portugal. Port wine is sweet wine so consumed as desert wine.
White wines are made from the grape juice and grape skin of green, gold or yellowish colored grapes or from just the juice (not the skin) of select red grapes (as in some Champagnes).
Champagne and sparkling wine
The Champagne we know and love comes exclusively from the Champagne region of France, and claims the honor of being the most famous of the sparkling wines. Technically, it is the only sparkling wine that may be referred to as "Champagne." Bubbly from all other regions in the world are simply referred to as "sparkling wine."
