With the launch of its wine “Luminoso Estate GSM,” Bodega Corazón del Sol, located in the Los Chacayes region, Uco Valley, province of Mendoza, marked a before and after in local viticulture by creating the first Argentine specimen composed of Grenache, Syrah, and Mourvèdre grapes, inspired by the great wines of the Rhône Valley in southern France. Corazón del Sol is also recognized for being a pioneer in planting Grenache and Mourvèdre in Tunuyán, in the Geographical Indication (GI) Los Chacayes, where it owns its vineyards. Fifteen years after that gamble made by Dr. Madaiah Revana, founder and owner of the winery and a renowned viticulturist in the most important wine regions of the United States, Napa Valley (California), and the Willamette Valley (Oregon), where he also produces high-end wines, Corazón del Sol invites you to discover and enjoy this unique blend acclaimed by experts worldwide.

Mendoza, November 2023. Corazón del Sol, the prestigious winery located in the Geographical Indication (GI) Los Chacayes, in the Uco Valley of Mendoza, founded and led by Dr. Madaiah Revana, celebrates in a vertical tasting its 10 vintages of “Luminoso Estate GSM,” its emblematic wine and the first wine in Argentina made with Grenache (Garnacha in Spanish), Syrah, and Mourvèdre (Monastrell in Spanish) grapes, with its first vintage being 2011.

Pioneers in planting Grenache and Mourvèdre in this region and in launching a blend with these varietals to the local market, which changed slightly in its composition over these ten years, it stands out for its complexity and elegance. From that first edition to the present, Luminoso Estate GSM has been highly praised by experts worldwide, distinguished by the most important wine critics such as Wine Spectator, Wine Advocate, Tim Atkin, and James Suckling, among others.

The visionary who marked a milestone in local viticulture Dr. Madaiah Revana emigrated from India to the United States in the early 70s, being a young and ambitious medical student. Currently, he balances his successful cardiology practice in Houston, Texas, with his commitment to the Revana Wine Portfolio.

Today, he is the only Indian immigrant who owns three wineries that have appeared on the Top 100 lists of Wine Spectator and are highly acclaimed by international specialized press. After founding and developing wineries like Revana Estate in Napa Valley (California) and Alexana Estate in the Willamette Valley (Oregon), both ‘Top 100’ wineries, Dr. Madaiah Revana arrived in Mendoza in 2008 and was amazed by the Uco Valley and its wines, especially the Los Chacayes region, where he envisioned the possibility of creating the first Argentine wines with these varieties.

In Mendoza, he had the privilege of meeting an icon of Argentine winemaking: winemaker Santiago Achaval, a pioneer of single-vineyard Malbec and old vines. Alongside Achával, as an advisor, he discovered the Los Chacayes region and right there, surrounded by thousands of hectares of native desert covered with countless stones, a few steps from the Arroyo Grande, Dr. Revana knew he was in the perfect terroir to fulfill his dream: planting a vineyard that would challenge the best Grenache, Syrah, and Mourvèdre specimens in the world.

Without knowing at all that he was betting on a terroir that ten years later would become the geographical epicenter of one of the most exciting wine regions in Argentina (the GI Los Chacayes), in 2008, Revana acquires 7 hectares of vineyards in The Vines. There, he planted the first vines of Grenache, Syrah, and Mourvèdre. In fact, today, most of the Grenache and Mourvèdre vines in the Uco Valley trace back to the stakes of the Revana Vineyard.

Years later, the grapes were harvested by hand and placed in a 10 hl tank for co-fermentation. In 2011, Luminoso Estate GSM was born, the first wine with that varietal composition in the history of Argentina.

In 2014, Revana began building his own winery, Corazón del Sol, and in 2016, he decided to open the establishment to tourism.

Corazón del Sol marked a before and after in local viticulture with its exceptional Luminoso Estate GSM, made with grapes from the estate located in the GI Los Chacayes. With slight variations in its composition and winemaking, over the last decade, the wine has shown a clear evolution, always highlighting the quality and elegant nuances it offers.
