RJ Viñedos is a family owned winery run by its founder, Raul Joffre, and his four daughters. The winery began in 1996 when Raul purchased and refurbished a traditional cement tank winery in the Perdriel region of Lujan de Cuyo and planted a small vineyard in the Los Sauces region of the Uco Valley. They now have 60 hectares in the Uco Valley as well as holdings in Alto Agrelo and up north in the Calchaquí Valley of Salta. Their vineyards are sustainably farmed, and no chemicals are used in the vineyards or in the winery. Winemaker Sebastián San Martin has a minimalistic approach where he believes in letting the grapes have their own voice and looks for purity of fruit with little intervention. They produce the Reunion and MDZ wines as well as a series of reserve wines.
