The Humbolt Current Influences the Taste of Chilean Wines

If you haven’t explored the Chilean wine sector in your local shop or online, now is the perfect time to rectify this oversight. Often overlooked and underreported, Chile boasts a wine region that consistently produces exceptional wines deserving of wider recognition.

Ingredients for Success

Chile’s geographical and climatic conditions are exceptionally well-suited for cultivating outstanding grape varieties. Stretching over 2,600 miles from north to south and measuring just 110 miles in width, this slender country benefits from the Pacific Ocean gracing its entire western border and the majestic Andes Mountains adorning its eastern coast. This unique combination of factors results in a harmonious interplay of cool Pacific breezes and the moderating influence of the mountains, creating an idyllic environment for grape cultivation.

Chile’s coastal terroirs are marked by two key elements that significantly contribute to the distinctive character and nuances of its wines: the Humboldt Current and the Coastal Range.

The Humboldt Current, also referred known as the Peru Current, is a cold oceanic flow that consistently imparts a cooling effect. Flowing north from Antarctica along the west coast of South America brings nutrient-rich water to the Galapagos Islands. Named after the naturalist Alexander Von Humboldt, this current is driven by strong winds that displace warm and nutrient-poor surface water, allowing the cold Antarctic waters to rise to the surface, creating an upwelling phenomenon. The Humboldt Current is one of the most productive ecosystems in the world, supporting the world’s largest fisheries, and is the reason why some species of penguins can thrive near the equator.

The Humboldt Current allows grapes to ripen slowly, preserving their distinct flavors. This gradual ripening process maintains herbal notes, such as jalapeno, asparagus, and grass, while also enhancing the wines’ citrusy fruitiness with hints of lime, lemon, and grapefruit. Almost every day, vineyards are enveloped in a protective blanket of fog that lowers air temperatures, creating an ideal environment for producing high-quality grapes.

The Coastal Range, a mountain range running along the Pacific Coast from north to south, plays a pivotal role in shaping the terroir of the region. This range houses various types of granite, with the western slopes directly influenced by cooling maritime conditions, and the eastern slopes acting as a barrier against the cold sea air. These site variations, combined with different soil types, yield a wide spectrum of styles among Chile’s coastal Sauvignon Blanc wines, offering a plethora of options for consumers to explore and savor.

Grape Arrival

Vitis vinifera grapes were introduced to Chile during the 16th century by Spanish conquistadors and missionaries who brought European vines to the region. Hernan Cortes and his soldiers exhausted the wine they brought with them from Spain to celebrate the conquest of the Aztec Empire in 1521. Consequently, one of Cortes’ first acts as governor was to order the planting of grapevines throughout New Spain.

In 1545, Pedro de Valdivia, the first royal governor of colonial Chile, sought vines from the King to aid in the evangelization of Chile. It is believed that Pais (Listan Prieto), a red wine grape, was among the first grape varieties introduced by the Spanish, with Rodrigo de Araya (1555) noted as the first Spanish conquistador to initiate agriculture in Chile, including the cultivation of vineyards.

The responsibility of tending to these early vineyards primarily fell upon Jesuit priests, who utilized the wine produced for religious purposes, particularly for the celebration of the Eucharist. Notably, during the 16th century, Chilean historian Alonso de Ovalle documented the presence of various grape varieties in addition to the common black grape, including muscatel, torotel, albillo, and morale, which were extensively planted in the region.

During the period of Spanish rule, the production of vineyards in Chile was subject to certain conditions, which required Chileans to purchase most of their wine directly from Spain. However, in 1641, the importation of wine from the Viceroyalty of Chile and Peru to Spain was banned, adversely affecting the colonial wine industry. This ban led to a surplus of grapes, which were subsequently used to produce pisco and aguardiente, nearly decimating Peruvian wine production.

Despite these restrictions, Chileans continued to prefer domestically produced wines over the oxidized, vinegar-rich wines imported from Spain, which did not withstand long voyages. They even exported some of their wine to neighboring Peru. However, one shipment was seized at sea by the British privateer Francis Drake. Instead of provoking Drake, Spain accused Chile and ordered it to destroy most of its vineyards, though this directive was largely disregarded.

French Influence

Chile’s wine history, despite its political ties with Spain, has been significantly influenced by French winemaking, particularly Bordeaux. Before the phylloxera epidemic, wealthy Chilean landowners visited France and began importing French grape varieties. Don Silvestre Errazuris was among the first to do so, introducing grapes like Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec, Sauvignon Blanc, and Semillon. He hired a French oenologist to oversee vineyards that produced Bordeaux-style wines. Recognizing the potential in Chile, he also attempted to cultivate the German wine grape Riesling.

The arrival of the phylloxera epidemic in France provided an opportunity for the Chilean wine industry. As French vineyards fell into disrepair, many French wine producers brought their expertise and skills to South America. Consequently, Silvestre Ochagavia Echazaret founded Ochagavia Wines in 1851, and Don Maximiano Errazuriz founded Vina Errazuriz in 1870, both using grapes imported from France.

About the Grapes

While some countries center their wine industries on one or two grape varieties, Chile is the opposite. Rigorous soil studies are part of the regular reviews by Chilean winemakers as they seek to determine the best grape varieties for their vineyard sites.

The Leyda Valley, a small sub-area of the San Antonio Valley located 90km west of Santiago and adjacent to the Pacific Ocean, is a cool-climate region influenced by the Humboldt Current. It produces vibrant and fresh wines, including Sauvignon Blanc, Chardonnay, and Pinot Noir. The soils of the Leyda Valley wine region are mostly composed of clay and loam, with a granite base that assists in water drainage. These soils are ideal for growing premium grapes that can adapt to low-fertility terroirs. The grapes are smaller, resulting in more concentrated juices.

Economics of Chilean Wine

Wine is produced in Chile from Atacama to Araucania, with vineyards running up and down the regions’ valleys. In 2021, there were 130,086 hectares of planted vines. In 2022, Chilean wine production totaled 1.244 billion liters, a 7.39 percent decrease from 2021. In 2022, Chilean wine export volume totaled 833.5 million liters, a 4.0 percent decrease from 2021, while domestic consumption reached 292 million liters.

Wine Futures

The Chilean wine industry’s primary collective goal is to champion its premium wines globally and eliminate its image as a cheap winemaking nation. Efforts initiated in 2018 have been successful, leading to a 20 percent increase in value sales in China and encouraging uplift in value sales in the US, Japan, South Korea, and Hong Kong.

Sustainability is of paramount importance to wine producers, and the Chilean government has pledged to be carbon neutral by 2050. In 2020, approximately 76 wineries, representing 80 percent of bottled wine exports, were certified sustainable. There is also an effort to reduce the quantity and weight of bottles and packaging to ensure that 100 percent are separable, reusable, recyclable, or compostable by 2030. Chile is not only producing exceptional wines but also committing to a sustainable and environmentally responsible future for the wine industry.
