I visited the Carneros AVA for the first time a couple months ago. This American Viticultural Area includes parts of both Sonoma and Napa counties. I was in Sonoma for a work conference so Carneros, just a few miles away, was perfect for a quick trip to a couple vineyards during a free morning. In March the land was too wet after a rainy season for me to fully explore the grounds at Schug but I could enjoy a few gorgeous views there and at surrounding vineyards.
Located just north of San Pablo Bay, the fog and cool breezes make the climate cooler in Carneros than in other areas in Napa and Sonoma. It is the coldest and windiest AVA in both Napa and Sonoma. This cooler climate is perfect for Chardonnay and Pinot Noir. I tasted several of both and enjoyed the 2013 Heritage Reserve Pinot Noir enough to travel home with a bottle. Currently, none of the wines at Schug are fined with animal products (whites from vintages prior to 2014 may have been fined using animal products so should be avoided by strict vegans).
The 2013 Heritage Reserve was a lovely example of a Pinot Noir. Light bodied, there was a bit of earthiness on the nose along with strawberries. This Pinot had medium acid and was a bit tart on the finish, with a nice berry taste. As with most Pinot Noirs, I would enjoy this with almost any savory food.
