I apologize to those of you bored backwards out of your underpants with the previous technical discussion. Lest you imagine I spend all of my time on such technical matters, please check out my recent posts at Appellation America concerning Petite Sirah. There are two articles — one popular, outlining the regional diversity we encountered in our tastings, and one more theoretical which speculates on the sources of regional diversity in the grape, and I believe offers useful framing of that discussion for other varietals.
