San Juan Province
Key Spanish Terms
Argentina's second-largest wine region, where intense sun and high-altitude valleys produce Syrah and Malbec of exceptional character.
San Juan is Argentina's second-largest wine region, accounting for 17% of the country's vineyard area across 32,000 to 46,000 hectares. The province spans five distinct valleys, from the warm Tulum floor to the high-altitude Pedernal, with Syrah as its signature grape. A historic bulk wine producer, San Juan is now firmly focused on premium wine.

Location and Landscape
San Juan Province sits north of Mendoza in the Cuyo Region of Northwest Argentina, bordered by La Rioja and Mendoza provinces. Vineyards range from 550 to 2,000 meters above sea level, and the entire region depends on irrigation supplied by the San Juan and Jachal rivers along with Andean meltwater. Soils are primarily alluvial with sandy extensions, while the Zonda Valley features calcareous soils with clay, gravel, and limestone components.
- Located north of Mendoza between La Rioja and Mendoza provinces
- Elevation ranges from 550 to 2,000 meters above sea level
- Irrigation sourced from San Juan and Jachal rivers and Andean meltwater
- Soils range from alluvial-sandy to calcareous-limestone depending on valley
Climate
San Juan has a warm, dry continental climate with approximately 150mm of annual rainfall, an average temperature of 17°C, and around 330 days of sunlight per year. These conditions produce ripe, fruit-forward grapes in the lower valleys, while higher elevations in Pedernal and Calingasta introduce cooler nights and greater diurnal variation, encouraging more mineral-driven, complex wine styles.
- Approximately 150mm annual rainfall, making irrigation essential
- Average temperature of 17°C with approximately 330 sunny days per year
- High-altitude sites experience greater diurnal temperature variation
- Warm conditions at lower elevations favor full-bodied, fruit-driven wines
Grapes and Wine Styles
Syrah is the defining red variety of San Juan, planted across all five valleys and producing wines with ripe fruit character and silky tannins. Malbec, Bonarda, Cabernet Sauvignon, Tannat, and Cabernet Franc are also widely grown. White varieties include Chardonnay, Sauvignon Blanc, Viognier, Torrontés, and Moscatel de Alejandría. The province has a strong tradition of producing Pedro Ximénez-based sherry-style and fortified wines, a legacy of its long history as a bulk wine and brandy producer.
- Syrah is the signature variety, grown in all major valleys
- Pedernal Valley internationally recognized for high-altitude Malbec
- Pedro Ximénez, Moscatel de Alejandría, and Chenin Blanc support fortified wine production

Open Wine Lookup →History and Classification
Viticulture in San Juan was introduced by Spanish conquistadors and Jesuit missionaries between 1569 and 1589, making it one of the oldest wine regions in Argentina. Through much of the 20th century, the province was a dominant producer of bulk wine, brandy, and vermouth. The shift toward premium wine began in the 1990s with experimentation in high-altitude vineyards. Today, San Juan operates under a Denominación de Origen Controlada framework and contains 25 Geographic Indications. Pedernal Valley received formal GI status in 2007 and remains the most internationally recognized appellation.
- Viticulture established by Jesuit missionaries between 1569 and 1589
- Major bulk wine and brandy producer through most of the 20th century
- Premium wine transition began in the 1990s via high-altitude experimentation
- Pedernal Valley GI status approved in 2007
Lower-valley wines are fruity, full-bodied reds with soft, silky tannins and ripe stone and dark fruit character. High-altitude wines from Pedernal and Calingasta show more mineral-driven complexity, fresher acidity, and greater structure. Fortified and sherry-style wines from Pedro Ximénez reflect the province's historic production tradition.
