Terroir of San Juan
San Juan's terroir is shaped by its elevation and dry climate. The main wine areas—Tulum, Zonda, and Ullum—are located at 600–700 meters above sea level, enjoying warm, dry seasons with little rainfall. Moving west, Pedernal and Calingasta rise to 1,200–1,700 meters, where hot days and cool nights help maintain grape acidity.
Pedernal's thin soils, rich in limestone, add freshness and mineral notes. Meanwhile, Calingasta's sandy, gravelly terraces allow grapes to ripen fully while keeping their acidity. The Tulum Valley has deep alluvial soils of sand, clay, and lime, offering a unique profile. With less than 100 mm of yearly rainfall, vineyards rely on Andean river irrigation. These conditions ensure low disease risk and plenty of sunshine, promoting full grape ripeness.
