RJ Vinedos is a family owned winery run by it's founder, Raul Joffre, and his four daughters. The winery began in 1996 when Raul purchased a traditional cement tank winery in the Perdriel region of Lujan de Cuyo and 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 Calchaquies de Cafayate Valley la Salta. The vineyards are all sustainably farmed and no chemicals are used, in both the vineyards and the winery. The winemaker Sebastian San Martin has a minimalistic approach as he believes in letting the grapes have their own voice, and looks for purity of fruit with little intervention.
