From the Washington Post:

Napa Valley wine producers will go a long way to protect their good name, all the way to Thailand if necessary.

That’s the latest country which has awarded Geographic Indication status to Napa wine, which means they’ve agreed not to allow sales of wine labeled “Napa” if the grapes inside aren’t from that California region.

The agreement, reached late last year, is part of a campaign for truth-in-wine-labeling laws supported by a loose-knit cohort of wine regions around the world — a movement that has gotten a boost from the general trend of consumers seeking ingredient integrity.

“What has been on our side is consumer awareness of, and appreciation for, the place where the product they’re consuming comes from and paying more attention to labels, paying more attention to how things are produced,” says Linda Reiff, executive director of the 420-member Napa Valley Vintners association.

For Napa Valley producers, the name campaign began during the late ‘90s on a defensive footing when producers lobbied for a 2000 state law requiring that any wine with “Napa” in its name consist of at least 75 percent Napa grapes.
