Great wineries to visit

Today we visited four wineries, Graton Ridge ( Russian River Valley), Rochioli (Dry Creek Valley), Porter Creek ( Dry Creek Valley) and Hop Kiln (Dry Creek Valley) all of which were impressive wineries.
Graton Ridge was established in 2007, I believe, and has already won medals for a few of their wines, so to say the least it is definately an up and comer... I personally think the Zinfindel needs to sit for a while so the fruit has a chance to develop, but when it does, watch out. I would get it now before it becomes a library.
Rochioli is amazing... The tasting room only offers two wines at a time that they release every couple of months and today, I tasted a Chard and a Pinot, which were both fantastic. Don't miss this one! I think they are releasing a Sauv blanc and another Pinot in a few months and I can't wait to try them.
Hop Kiln has good wine, but nothing that really stood out and slapped me in the face. Very interesting story behind the building itself though - you should read up on it. "1000 flowers" was nice on the palate as wall as their "Big Red" Bordeaux blend.
Porter Creek was great. The welcome was warm, and the service was impecable, as well as the wine. Excellent Chard and Pinot - they also had a reserve Pinot that wasn't open unfortunately, because I'm sure it would have been great. Right down the road from Rochioli too. If your in the area, I suggest you kill two bird with one stone. Really good Viognier.
All and all, I would consider today a success for sure. These are four wineries/vineyards that I wouldn't miss if I were you. If you have a chance to visit, please let me know what you think.

Blackstone

WOW! The blackstone reserve list is amazing. Excellent Pinot noir, balanced acidity, light but firm tannins, A mix of light and dark berries on the palate. Great chard as well, oakey but not overly oakey as well as buttery(I believe it is fermented in first year toasted french oak) but it is not offensive what so ever. Very nice finish. The merlot's I tasted were young and needed a few more years in the bottle but very promising to say the least. I was thuroughly impressed with both the wines and the warm welcome... It's a must visit!
The zin's and cabs were not as big as I expected but good none the less. The real gem was by far the Malvasia bianca, tropical, fun, fruity and just a great wine all around. I was also impressed with the Gewurtztraminer... Nice fruit and hints of all the right spices. Don't miss this one!
