Matthews Winery

United States

Philosophy

Minimalist hand-crafted blends across multiple clones and vineyard sites, with extended maceration and cold-soaking protocols. Fruit sourced from diverse Columbia Valley sub-appellations—Royal Slope, Red Mountain, Horse Heaven Hills—yielding wines of polish and freshness, neither oaken nor extracted, marked by precision tannin integration and terroir specificity rather than power.

Reputation
