what’s going on in Temecula?

Met some people last night involved in an interesting wine venture in Temecula, near San Diego.  I had followed early wineries like Callaway, who did unexpectedly lovely dessert wines there in the 80s and 90s. Apparently there’s still more good vineyard land there, and investor groups have been planting and making wine.  Tried one experimental Cabernet Sauvignon — 2005, very soft, with surprising cassis fruit –  but need more info to really make a judgement.
