The new/Feb issue has an excellent article by DavidDarlington, one of the very best wine writers in the USofA, on Rieslings from the PotterVlly in MendoCnty.
Unfortunately currently available for subscribers only.
It features a lot about Guinness McFadden, who sells his R to Ch.Montelena & MikeDashe. I've long felt Mike's McFadden R is one of the best in Calif.
R does well there because of the altitude giving a large di-urnal cycle. Didn't realize that Potter vlly is a 3 times the altitude of the AndersonVlly.
Anyway, worth buying the latest W&S for David's article.
