About Charles vineyard

Established in 2001 by William and Nancy Charles, Charles Vineyard is located just southeast of the town of Boonville and is planted primarily to Pinot Noir and Sauvignon Blanc. In our location we can experience daily temperature swings of up to 55 degrees Fahrenheit (sometimes more), which adds to the rich flavors and strong acid profile of our grapes. Winters can be very wet, as the annual rainfall in Boonville averages 41.6 inches. Fortunately, our vineyard sits on an ancient river bend, which means our well-drained soils are suited to this annual moisture level. The modern-day version of this ancient river, called Anderson Creek, now borders our property on the east, separating us from the eastern foothills of the valley. All vineyard work is done by our family, with help during pruning and harvest. On any given day you can find us in the vineyard, performing one of many tasks that keep our vineyard healthy and producing the best quality fruit possible. We practice what we like to call vine-by-vine viticulture: Spending so much time in the vineyard enables us to know the vines' particular needs and tend them accordingly, from adjusting compost levels to changing pruning techniques. We live on our land, and so farm our vineyard sustainably and responsibly, to ensure that the vineyard, and our family, is healthy and happy for years to come.
