About Robert Clay Vineyards

Robert Clay Vineyards in the tiny community of Streeter, Texas is the first Texas commercial grower of Touriga Nacional. Cultivating a wine grape variety that has no history in a new environment requires a bit of innocent naiveté, a calm understanding of self, and a complete disregard for punditry. Then, the magic can happen.
