O’Brien Estate has just been named #1 winery and travel destination in Napa Valley by U.S. News and World Report!

From planting to bottling , the entire wine-making process occurs on this relatively small plot of land (comprising 40 acres of vineyards, a winery and the owner’s home). And by all accounts, the end result is a hit with visitors. Consider a tasting at O’Brien Estate Winery if you’re looking for a relaxed, intimate atmosphere with personalized service. Recent visitors raved about the staff, who share interesting and educational facts about the winery, but also give plenty of alone time to kick back, relax and savor the tasting experience. Expect stunning views of the Oak Knoll District and a sampling of five of the estate’s wines.
