White wine has hundreds of grape varieties that are grown around the world. White wine gets its color from the grape juice and grape skins of green, gold, or yellowish colored grapes. White wine ranges in color from yellow-gold, yellow-green, to straw-yellow depending on the grape variety that is used to produce the wine. Some white wines are fermented in steel and then allowed to mature in oak while other white wines are fermented and aged in oak barrels. White wines that are exposed to oak tend to have a pale color with an extra silky texture. Only about 5% of white wines taste better after being cellared for 5 years than it would after just 1 year. White wines are at their best when presented in a narrow glass with a tapered top to allow for aromatic concentration. White wine should be served between 45-50 degrees Fahrenheit for optimum bouquet / flavor presentation. White wine that is served too warm is overwhelmed by alcohol. White wine that is served too cold will lose the wine's bouquet.
