Otronia 45 Rugientes Corte de Blancas 2019

Winery Background and History

Otronia is a pioneering winery located in Sarmiento, Chubut, Argentina, at latitude 45°33′S, making it one of the southernmost vineyards globally. Established in 2010, the estate spans 50 hectares dedicated to organic viticulture. The extreme Patagonian climate—characterized by constant winds, low humidity, and significant diurnal temperature variations—contributes to the unique expression of their wines. Otronia’s commitment to sustainability and innovation has positioned it as a leader in crafting wines that reflect the purity and authenticity of this remote terroir. 

Producer and Winemaker

The winemaking team at Otronia is led by Juan Pablo Murgia, who has been instrumental in crafting wines that capture the essence of Patagonia’s extreme terroir. His approach emphasizes organic viticulture and minimal intervention, allowing the unique characteristics of the region to shine through in each bottle. Murgia’s dedication to quality and innovation has positioned Otronia as a pioneer in Patagonian winemaking. 

Vineyards and Micro Climate

Otronia’s vineyards are situated at an altitude of 258 meters above sea level in the Patagonian steppe. The soils are diverse, comprising lacustrine origins with clays, fluvial and alluvial rocks, and aeolian sands. This heterogeneity necessitated dividing the estate into 45 distinct blocks to manage the unique characteristics of each parcel. The region experiences a continental cold climate with significant diurnal temperature variations, which contribute to the development of natural acidity and aromatic intensity in the grapes. The persistent Patagonian winds and low humidity levels create conditions that are conducive to organic viticulture, as the dry environment minimizes disease pressure. These extreme conditions result in wines with remarkable freshness, purity, and a distinct sense of place. 

Vinification & Aging Methods

The grapes for this blend were hand-harvested in the early morning hours to preserve their freshness. They were directly pressed using a pneumatic press without destemming and at low pressure, separating the free-run juice from the press fraction. After static settling, each varietal component fermented separately in stainless steel tanks and concrete eggs, utilizing indigenous yeasts to foster a natural expression of the terroir. Following fermentation, the blend was assembled and aged for 20 to 22 months in unroasted French oak foudres and concrete vats. This aging regimen aimed to enhance the wine’s complexity and texture without imparting overt oak flavors, allowing the purity of the fruit and the distinct characteristics of each varietal to be showcased. 

Tasting Notes

The 2019 Corte de Blancas displays a pale yellow hue with greenish reflections. The nose is warm and inviting, offering aromas of lemon, ripe pear, and subtle grassy notes. On the palate, the wine is zippy and vibrant, featuring flavors of lemon, pear, and a hint of grassiness. The finish is clean and refreshing, leaving a lasting impression of its crisp acidity and well-integrated flavors. 

Food & Wine Pairing

This versatile blend pairs well with a variety of dishes. Its bright acidity and aromatic profile make it an excellent match for seafood, such as grilled fish or shellfish. The wine’s complexity also complements spicy Asian cuisine, where its slight sweetness and spice can balance the heat. Additionally, it pairs nicely with soft cheeses and dishes featuring fresh herbs, enhancing the overall dining experience. 

Service Methods and Temperatures

To fully appreciate its aromatic complexity and freshness, serve this wine well-chilled at around 8–10°C (46–50°F) in medium-sized white wine glasses. This temperature accentuates the wine’s vibrant acidity and allows its nuanced aromas to shine. It’s recommended to open the bottle shortly before serving to preserve its delicate aromatics. 

Storage and Aging Potential

While the 2019 Corte de Blancas is enjoyable upon release, displaying vibrant fruit flavors and crisp acidity, it also has the potential to develop additional complexity with short-term cellaring. When stored properly in a cool, dark environment with stable temperatures, it can be enjoyed over the next 3 to 5 years, during which it may develop richer textures and more integrated flavors.
