DeLille is right across the street. The tasting room is inviting in an unpretentious way; guests can stand at the bar or congregate around tables, either way getting plenty of attention from a very knowledgeable staff person. The estate's grapes are in the Red Mountain AVA, a bit north of Walla Walla. Currently they have twenty acres of Cabernet Sauvignon and Syrah, planted in 2000 and cut down after three years to jump-start the vines' maturation. The winery sources other fruit from the Red Mountain and Yakima Valley AVAs. These wines are definitely French style: dry, smooth...even silky, with lots of nuances. We loved the 2010 Roussanne, 2008 Syrah, and 2006 Grand Cru Estate Cab.
