Tandem - meaning `at last` - was founded in 2003 as a collaboration between experienced viticulturalists and vine-growers. Based in the Valle de Yeri, a relatively cool area in Navarra, they work with Tempranillo, Granacha, Graciano, Cabernet Sauvignon, Merlot, Viognier and Viura. Their winemaking facilities are state-of-the-art, and they release their wines only when they ready to drink. /JH
