Arch Terrace Merlot

Terra Blanca is a family-owned estate winery on the southwest slope of Red Mountain, Washington, founded by Keith and ReNae Pilgrim. The estate spans 300 acres, with approximately 91 acres planted to 19 grape varieties, and produces wines from its own vineyards. Keith Pilgrim, a UC Davis-trained geologist with viticulture and enology training, serves as owner and winemaker, supported by Kristin Pilgrim. The winery emphasizes careful, place-driven winemaking and sustainable growing practices intended to reduce environmental impact, without citing formal certifications. Its vineyards are marked by calcium-carbonate-rich soils, comparable to limestone and chalk. Tuscan-inspired architecture, barrel caves, and tasting rooms form part of the estate experience.
