From Distillers Wiki
Classic white wine variety commonly planted in the Bordeaux and eastern Loire regions of France. Still a widely grown varietal in the U.S., its production has declined in favor of the popular Chardonnay. It shows a tendency towards a grassy, herbaceous flavor in the wine when the grapes are grown in temperate regions. In warmer regions, the flavors and aromas tend to be more citrus, (e.g: grapefruit or pear), plus the characteristic "earthy" taste. New Zealand has had much success with this grape in recent years.
