White Grape Variety
Definition - What does White Grape Variety mean?
In the context of wine classification, white varietal refers to the color of the pulp and skin of white wine grapes and is a simple classification of different characteristics between wine grapes. White varietals are descended from red varietal grapes and can be pale green, yellow or even have a pink or blue hue in color; this is due to a genetic mutation that turns off the production of anthocyanins, which gives grapes their color.
White varietal grapes have less tannins then red grapes, which typically gives white wines a lighter mouthfeel. While there are hundreds of white varietal grapes, well known white varietals include; Sauvignon Blanc, Chardonnay, Semillon, Pinot Grigio, Moscato, Riesling and Gewurztraminer.
