(Washingtonpost) - 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.
