Wine Regions of Argentina and Their Biggest Wines

Argentina, known for its vibrant culture and breath-taking landscapes, is also making a name for itself in the world of wine. With its rich history, diverse terroir, and dedication to quality, Argentina has become a prominent player in the global wine industry. In this article, we will explore the enchanting wine regions of Argentina, their unique characteristics, and the wines they produce.

Discovering the Wines of Mendoza

Located on a high-altitude plateau at the edge of the Andes Mountains, the province of Mendoza is the heartland of Argentine wine production. It is responsible for approximately 70 percent of the country's annual wine output. The region's diverse terroir, combined with its dedication to the French grape variety Malbec, has resulted in the production of red wines of exceptional concentration and intensity.

While Malbec shines as the star of Mendoza, other grape varieties also thrive in the region. Cabernet Sauvignon, Chardonnay, Syrah, Torrontes, and Sauvignon Blanc are among the extensive plantings found in Mendoza. In recent years, the region has also begun to make a name for itself as a producer of sparkling wines.

The vineyards of Mendoza are clustered mainly in the northern part of the province, in regions such as Lujan de Cuyo, Maipu, and the Uco Valley. Mendoza City, the capital of the province, has become a hub for wine tourism, offering visitors a chance to explore the region's wineries and indulge in wine tasting experiences. The city hosts the Fiesta Nacional de la Vendimia (National Harvest Festival) in March, a vibrant celebration of the harvest season that showcases the best of Mendoza's wines.

A Glimpse into the History of Mendoza's Winemaking

The winemaking history of Mendoza dates back centuries, closely intertwined with the colonial history of Argentina itself. The first vineyards were planted by Jesuit priests in the mid-16th century, drawing on agricultural techniques learned from the indigenous Incas and Huarpes. Spanish missionaries are believed to have introduced grape varieties, including the ubiquitous Mission/País grape, for sacramental use.

In the mid-19th century, Malbec was brought to Argentina, often credited to French agronomist Michel Aimé Pouget. However, some sources suggest that Malbec's establishment in Argentina predates Pouget's arrival. Regardless of its origins, Malbec has found its home in Mendoza and is celebrated on World Malbec Day, observed on April 17th.

The development of Mendoza's wine industry received a significant boost in the late 1800s with the completion of a railway line connecting Mendoza to Buenos Aires. This transportation link provided a more accessible way to send wines out of the region, leading to a boom in wine production. Spanish and Italian immigrants, seeking refuge from the phylloxera epidemic devastating vineyards in Europe, further contributed to the growth of the industry.

The Influence of Climate and Geography

Mendoza's unique terroir, shaped by the towering presence of the Andes Mountains, plays a crucial role in the quality of its wines. The vineyards, situated between 800 and 1200 meters (2600 to 3900 feet) above sea level, benefit from the region's high altitude and continental climate. Warm, sunny days are followed by cooler nights, thanks to the westerly winds from the Andes. This diurnal temperature variation slows ripening, allowing the grapes to develop rich flavour's while retaining acidity.

Irrigation in Mendoza is facilitated by the rivers that flow through the region, including the Mendoza River. The warm, dry harvest periods ensure that winemakers can pick their grapes based on ripeness rather than weather constraints. This predictability contributes to consistent quality and reduced vintage variation.

The soils of Mendoza are primarily of Andean origin, deposited over thousands of years by the region's rivers. These sandy and clay-based soils are free-draining and low in fertility, forcing the vines to work hard for hydration and nutrients. The result is small, concentrated berries that impart structure, firm tannins, and a distinctive minerality to the wines.

Exploring the Unique Terroir of La Rioja

Another notable wine region in Argentina is La Rioja, located in the northwest of the country. With its fertile oases and arid mountain ranges, La Rioja offers a unique combination of conditions for grape cultivation. The region is characterized by a warm, dry climate with moderate night-time temperatures and limited rainfall.

The most prominent grape variety in La Rioja is Torrontes Riojano, a native variety that belongs to the family of Criolla grapes. White wines from the region often display greenish hues and intense fruity aromas. They have a medium structure and moderate to low acidity. While Torrontes Riojano takes the spotlight, other grape varieties like Malbec, Cabernet Sauvignon, Bonarda, and Syrah also thrive in the region.

La Rioja's winemaking history can be traced back to the mid-16th century when Spanish missionaries introduced grapevines, primarily for sacramental purposes. The region experienced a boom in wine production in 1885 with the completion of a railway line connecting Mendoza to Buenos Aires. This improved transportation allowed for easier distribution of wines from La Rioja to the rest of the country.

The Enigmatic Wines of San Juan

San Juan, the second-largest wine-producing province in Argentina after Mendoza, accounts for 16 percent of the country's total vineyard area. The vineyards of San Juan are spread across several valleys in the central-western part of the province, including Pedernal, Calingasta, Zonda, Ullum, Iglesia, and Jachal. These valleys offer ideal conditions for producing fruit-forward wines with unique character and style.

The warm and dry climate of San Juan, combined with the influence of altitude, latitude, and ample sunlight, creates differential temperature and humidity conditions in a semi-arid environment. The region is known for its strong presence of the Torrontes Riojano grape, a native variety that belongs to the Criolla family. White wines from San Juan exhibit a medium intensity of color with greenish hues, intense fruity aromas, and moderate acidity and structure. Additionally, grape varieties such as Malbec, Cabernet Sauvignon, Bonarda, and Syrah thrive in the region.

San Juan's viticultural success can be attributed to its unique terroir and the dedication of its winemakers. The province's diverse soils, ranging from alluvial sands to clay, provide a solid foundation for viticulture. The region's warm, dry climate and low incidence of precipitation, along with the availability of water from melting snow caps, contribute to the production of wines with exceptional quality and character.

The Charm of Salta's High Altitude Vineyards

In the northernmost wine region of Argentina, Salta stands out for its high-altitude vineyards. The province is home to some of the highest vineyards in the world, reaching elevations of over 2000 meters (6560 feet) above sea level. The combination of altitude, unique microclimates, and the influence of the Andes Mountains creates a terroir that produces wines of exceptional quality and intensity.

Salta is known for its signature grape variety, Torrontes, which thrives in the region's high-altitude vineyards. The Torrontes grape produces aromatic white wines with floral and fruity notes, often likened to Muscat. Alongside Torrontes, red grape varieties such as Malbec, Cabernet Sauvignon, and Tannat also thrive in Salta's vineyards.

The extreme conditions of Salta's high-altitude vineyards pose challenges for viticulture, including large diurnal temperature variations and low humidity. However, these challenges are embraced by winemakers who recognize the unique character and flavour profile that can be achieved in this region. The resulting wines are known for their intense colours, complex aromas, and remarkable concentration.

The Rise of Argentine Wine on the International Stage

Argentina's wine industry has come a long way in the past few decades, transitioning from a focus on the domestic market to gaining recognition on the international stage.
