Matthews Cuvée is crafted from several vineyards across the Columbia Valley, Royal Slope, and Red Mountain AVAs. The grapes are farmed using sustainable practices and hand-harvested in the early mornings. Upon arriving at the winery, each cluster is hand-sorted, berry-sorted, and then fermented in either concrete or stainless-steel tanks. The free-run wine is then moved to French oak barrels for cellaring. The resulting barrels are bottled without fining or filtration.
