Clark Smith (Appellation America), a wine writer/winemaker for whom I have a huge amount of respect is one of the culprits for the misuse of the term. According to him (and I will quote him), "You're fighting a lost war and you should direct your energy and efforts towards something more important." Well, with the support of Lisa Granik MW who also shares this view that we should set an example and make sure that the English language is properly used, Clark agreed that he will start using "grape varieties" from now on and, during his rehabilitation process, I could pinch his arm.
Don't you love happy endings? :)
Will you join my fight? :)
