Todd, we were is a similar situation a couple years ago. Went with Pride on one side the the valley, and Chappellet on the other side. We weren’t disappointed. The drives alone are worth it.
The family of a good friend of mine, fellow Berserker Scott Nelson, has a boutique winery called H.L.R. Cellars located on the Napa/Sonoma county line, about a mile away from Diamond Mountain. Scott recently moved from Chicago to St. Helena. Scott brought a couple of wines to a recent dinner and it seems that they make expressive Bordeaux blends from estate fruit at a fair price point. I think they would be worth checking out and I’m sure if you PM’d Scott he’d be happy to provide you with more info.
I’m going to Nine Suns on Prichard Hill next Friday and will report back. I hear they are making some killer juice. I’m a big fan of Spring Mountain Elivette, so on that mountain there where I’d go, unless the budget will allow for Lokoya. I think Stonestreet Winery in Healdsburg is also a great call. Their single vineyard mountain cabs are great QPR, especially the 2013s which are being offered right now.
There’s a tiny operation in Sonoma’s Mountain AVA run by Mr Phil Coturri and his son, Sam. I really enjoyed the Grenache from Winery Sixteen 600, but they also bottle a Syrah, a Cabernet Sauvignon, and a GSM-style red called “L’Hommage a’ Galet”. Available only at the tasting room are a Viognier, a “Val Rossi” red, and a couple of other wines.
