Dave Faries — Lake County Publishing Winemakers Matt Hughes of Six Sigma and Joy Merrilees of Shannon Ridge evaluate a wine in celebration of International Tempranillo Day on Thursday. Six Sigma annually invites local winemakers to try flights of the varietal, including several Lake County labels. At yesterday’s tasting examples from Brassfield Estate, Six Sigma and Shannon Ridge drew more praise than wines from Spain, Oregon and other regions in California.
