Environmentally sound and sustainable vineyard practices are at the core of our management philosophy. The SeVein partners and NSM team are active members in VINEA, the Walla Walla Valley Appellation certified sustainable viticulture organization. Focused attention on soil health is essential to growing healthy plants capable of withstanding disease and pest pressures. It also ensures these vineyards will produce great wine grapes for generations to come.
