Argentina: Land of Malbec and Mountain Vineyards
Argentina stands as South America’s largest wine producer, with a viticultural tradition dating back over 450 years. While once known primarily for high-volume production, the country has transformed its wine industry over the past three decades, now creating sophisticated wines that compete with the world’s finest offerings.
Mendoza: The Heart of Argentinian Wine
Nestled in the eastern foothills of the Andes, Mendoza dominates Argentinian wine production, accounting for nearly 70% of the country’s total output. This region’s exceptional conditions create the perfect environment for vineyards to thrive. The combination of high altitude, intense sunlight, and low humidity provides ideal growing conditions for many grape varieties, particularly Malbec, which has become Argentina’s vinous calling card.
Mendoza encompasses several important sub-regions, each contributing unique characteristics to its wines. Luján de Cuyo, often called the “Primera Zona,” produces structured, intense Malbecs from vineyards situated between 3,000 and 3,600 feet above sea level. The traditional area of Maipú creates wines with softer tannins and approachable fruit profiles, perfect for earlier consumption.
The Valle de Uco has emerged as Mendoza’s most exciting wine frontier. Vineyards here reach elevations of 5,000 feet, where cool nights preserve acidity while sunny days ensure perfect ripening. The result manifests in wines with incredible balance, aromatic complexity, and aging potential. This high-desert region relies on snowmelt from the Andes for irrigation, creating a controlled growing environment where vintners precisely manage water stress.
Salta and the World’s Highest Vineyards
Further north, Salta province hosts some of the world’s most extreme vineyard sites. The Calchaquí Valleys contain vineyards planted at altitudes reaching an astonishing 10,000 feet above sea level. These elevations produce wines with intense color, powerful structure, and remarkable concentration.
Cafayate, Salta’s primary wine district, has gained recognition for exceptional Torrontés, Argentina’s signature white grape. Here, the variety develops enticing floral aromas reminiscent of roses and jasmine, alongside bright citrus flavors. The dramatic diurnal temperature shifts—often exceeding 40°F between day and night—preserve acidity while allowing full flavor development in both white and red varieties.
San Juan and La Rioja: Emerging Regions
South of Mendoza, San Juan represents Argentina’s second-largest wine region. Historically focused on bulk production and grape concentrate, this area has recently pivoted toward quality wines, particularly from Syrah and Bonarda. The warmer climate yields richer, fuller-bodied expressions compared to Mendoza’s wines.
La Rioja, Argentina’s oldest wine region, specializes in Torrontés Riojano, producing wines with distinctive tropical fruit notes. The region’s renewed focus on quality over quantity has attracted investment and attention from wine connoisseurs seeking new experiences.
Key Grape Varieties and Wine Styles
While Malbec dominates Argentina’s wine identity, the country produces exceptional wines from numerous other varieties. Cabernet Sauvignon, Merlot, and Syrah thrive in many regions, creating powerful yet balanced red wines.
Bonarda (genetically identical to California’s Charbono) ranks as Argentina’s second most planted red variety, producing fruity, accessible wines with moderate tannins. Increasingly, producers are creating serious, age-worthy Bonarda from old vines and limited yields.
Among white varieties, Torrontés remains Argentina’s most distinctive offering, while Chardonnay and Sauvignon Blanc excel in cooler zones like southern Mendoza and Patagonia. Traditional-method sparkling wines have also gained traction, with high-altitude vineyards providing ideal conditions for base wines with precise acidity.
Climate and Terroir Characteristics
Argentina’s wine regions benefit from continental climates modified by altitude. Most vineyards exist in semi-desert conditions where annual rainfall rarely exceeds 10 inches. This necessitates irrigation but also minimizes disease pressure, enabling many vineyards to farm organically without difficulty.
Soils vary significantly across growing regions, from sandy loams in eastern Mendoza to the prized alluvial soils with limestone components found in Valle de Uco. Many vineyards feature large rocks and stones that store daytime heat and release it during cool nights, helping maintain even ripening conditions.
Signature Wineries to Know
Several pioneering producers have helped establish Argentina’s reputation for world-class wines. Catena Zapata, led by Dr. Nicolás Catena and his daughter Laura, conducted groundbreaking research on high-altitude viticulture that revolutionized Argentine winemaking. Their Adrianna Vineyard Malbecs showcase the stunning potential of extreme mountain sites.
Achaval-Ferrer focuses on single-vineyard expressions from historic old vines, while Zuccardi has pushed boundaries with their research into soil mapping and microterroir expression in Valle de Uco. Bodegas Colomé in Salta maintains some of the world’s highest and oldest Malbec vineyards, producing wines of extraordinary concentration and complexity.
Chile: Pacific Influence and Diverse Valleys
Chile’s unique geography—sandwiched between the Pacific Ocean and the Andes Mountains—creates distinctive growing conditions that differ dramatically from its neighbor across the mountains. With a viticultural history dating to the 1550s, Chile enjoys natural protection from many common vine pests, allowing widespread organic farming and minimal intervention.
Central Valley Wine Regions
Chile’s winemaking heartland lies in its Central Valley, composed of several interconnected valleys running north to south between Santiago and the Bío Bío River. Each valley possesses distinct characteristics influenced by proximity to the ocean or mountains.
The Maipo Valley, closest to Santiago, has built its reputation on exceptional Cabernet Sauvignon. Often compared to Bordeaux, Maipo Cabernets feature elegant structure, fine tannins, and characteristic notes of eucalyptus and mint derived from the region’s native vegetation. The area divides into Alto Maipo (closer to the Andes, with stony soils producing structured, age-worthy wines) and Central/Lower Maipo (warmer conditions yielding softer, earlier-maturing styles).
Casablanca Valley pioneered cool-climate viticulture in Chile, with its location just 30 kilometers from the Pacific bringing morning fog and cool breezes that moderate temperatures. This maritime influence creates ideal conditions for aromatic white varieties like Sauvignon Blanc and Chardonnay, along with elegant Pinot Noir and cool-climate Syrah.
Colchagua Valley, further south, focuses on powerful red wines, particularly from Carmenère, Cabernet Sauvignon, and increasingly, Mediterranean varieties like Grenache and Mourvèdre. The valley’s diverse microclimates range from cooler coastal zones near Paredones to warmer interior sections around Santa Cruz, offering vintners numerous stylistic possibilities.
The Revival of Carmenère
Carmenère holds a special place in Chile’s viticultural story. Once prevalent in Bordeaux but nearly extinct after phylloxera devastated European vineyards, this variety was rediscovered in Chile in 1994, having been mistakenly cultivated as Merlot for generations.
Initially challenging to work with due to its late ripening and tendency toward green characteristics when harvested too early, Carmenère has become Chile’s signature grape. Modern viticulture techniques focusing on reduced yields, appropriate site selection, and precise harvest timing have transformed Carmenère into a distinctive variety producing medium-bodied wines with spicy red fruit, herbaceous notes, and smooth tannins.
Coastal Influence on Chilean Viticulture
Chile’s coastal regions have driven much of the country’s qualitative revolution. The cold Humboldt Current flowing northward along Chile’s coastline creates cooling effects that penetrate inland through river valleys, moderating temperatures and extending growing seasons.
The San Antonio and Leyda Valleys, Chile’s coolest growing regions, sit just 4 kilometers from the ocean. These areas produce taut, mineral-driven white wines and structured Pinot Noir and Syrah with pronounced savory characteristics. Their granite and clay soils contribute additional complexity to wines that showcase Chile’s exciting cool-climate potential.
Northern and Southern Regions
Chile’s viticultural frontier continues expanding north and south. The northern Elqui and Limarí Valleys, historically known for pisco production, now create distinctive wines influenced by limestone soils and the cooling effects of the Camanchaca (coastal fog). These regions excel with Chardonnay, Sauvignon Blanc, and increasingly, Syrah.
Southward, Bío Bío and Malleco push Chilean viticulture into cooler realms, where later-ripening varieties struggle to mature but early-ripening grapes like Pinot Noir, Chardonnay, and Riesling develop exceptional aromatic complexity and vibrant acidity. These southern zones represent Chile’s response to climate change, as vintners seek cooler sites for the future.
Organic and Biodynamic Movements
Chile leads South America in sustainable viticulture, with natural geographic isolation protecting vineyards from many pests and diseases. This advantage allows widespread organic farming, with many producers taking further steps into biodynamic and regenerative practices.
Pioneers like Emiliana Vineyards (the world’s largest organic and biodynamic wine producer) and Matetic have demonstrated that ecological approaches enhance wine quality while protecting Chile’s diverse ecosystems. The country’s Sustainability Code certification program has further encouraged environmentally responsible practices across the industry.

Concha y Toro’s Don Melchor stands as Chile’s most consistent ultra-premium Cabernet, while their Terrunyo line showcases distinctive terroir expressions.
Smaller producers like Pedro Parra (focusing on granite-soil Cinsault and Pais in Itata) and Roberto Henriquez (reviving traditional winemaking methods with ancient-vine País) represent Chile’s new wave, exploring forgotten regions and varieties with minimal-intervention approaches.
Uruguay: The Tannat Specialist
Often overshadowed by its larger neighbors, Uruguay has cultivated a distinctive wine identity centered around Tannat, a variety originated in southwest France but now produces its most compelling expressions in South American soils. This small nation benefits from a moderate maritime climate that distinguishes it from other South American wine regions.
Coastal Atlantic Influence
Unlike the primarily continental climates of Argentina and Chile, Uruguay’s wine regions experience significant Atlantic Ocean influence. This maritime effect moderates temperature extremes, resulting in more consistent growing conditions with higher humidity and rainfall. The absence of dramatic mountain ranges means vineyards rarely exceed 500 feet in elevation, relying instead on gentle hills and river influences for mesoclimatic variation.
These conditions produce wines with moderate alcohol levels, refreshing acidity, and expressive aromatics—quite different from the powerful high-altitude wines found elsewhere in South America. The Atlantic’s cooling effect particularly benefits Tannat, tempering its naturally fierce tannins while preserving structural integrity.
Tannat’s Transformation in Uruguayan Terroir
Tannat arrived in Uruguay in the 1870s, brought by Basque immigrant Pascual Harriague. While the variety produces massively tannic, sometimes astringent wines in its French homeland of Madiran, Uruguay’s climate and soils transform Tannat into something more approachable while maintaining its distinctive character.
Uruguayan Tannat displays deep color, moderate tannins (compared to its French counterpart), and complex flavors of dark berries, plum, licorice, and spice, often with subtle floral overtones. Modern winemaking techniques, including micro-oxygenation and careful oak regimes, have further refined the variety, creating wines that balance power with drinkability.
Key Regions: Canelones, Maldonado, Carmelo
While Uruguay has four official wine regions, three dominate quality production. Canelones, surrounding the capital Montevideo, represents the country’s traditional winemaking heart, accounting for approximately 60% of production.
