In 1900 Rudolf Otto Suter and his wife and journeyed to Argentina from Switzerland and planted the first Riesling variety in the country. Today the fourth generation of the family continues to produce fine white wines, Malbec, Cabernet Sauvignon, Chardonnay and Spumante. A tour through this spotless winery leads you through a labyrinth of underground caves filled with huge oak casksÑused more to evoke atmosphere than to store wine.
