Torrontés

Torrontés is a white grape variety, mostly produced and known in Argentina, producing fresh, aromatic wines with moderate acidity, smooth texture and mouthfeel as well as distinctive peach and apricot aromas on the nose. Three Torrontés varieties exist in Argentina: Torrontés Riojano, the most common, Torrontés Sanjuanino, and Torrontés Mendocino. It is primarily Torrontés Riojano that has received attention for the quality of its wines, and is the variety used for most Argentine wines simply labeled Torrontés.

The three grapes are relatively similar but do have some noticeable differences. Torrontés Riojano and Torrontés Sanjuanino both tend to have large loose bunches of pale grapes while Torrontés Mendocino, however, has smaller, tighter bunches of darker yellow grapes. Torrontés Riojano is the most aromatic of the three, with aromas reminiscent of Muscat and Gewürtztraminer wines. The least aromatic, and least widely planted, is Torrontés Mendocino with the aromatics and plantings of Torrontés Sanjuanino falling in between. All three Argentine Torrontés varieties belong to the Criollas group of grape varieties, which is a term used for presumably American-born cultivars of the European grapevine Vitis vinifera.

Around 8,700 hectares (21,000 acres) in Argentina have been planted with Torrontés Riojano, and 4,850 hectares (12,000 acres) with Torrontés Sanjuanino. Plantings in the very high altitudes (1700m+) of the Calchaquíes Valleys in the far north of Argentina have recently met with success. The vine is highly productive and is just under ten percent of all white grape plantings, however as a varietal, it made up almost 20 percent of all white wine sold in Argentina in 2008. The Salta region in northwest Argentina is particularly noted for its Torrontés as the grape thrives in cold dry, windswept conditions.

Recent research using DNA profiling has shown that the different Torrontés are genetically closely related but distinct grape varieties, and that Torrontés Riojano, Torrontés Sanjuanino, and Torontel (also known as Moscatel Amarillo) are all separate crossings of Mission (originally reported as Criolla Chica) and Muscat of Alexandria. Torrontés Mendocino was found to probably be a crossing of Muscat of Alexandria and another, so far unidentified grape variety. While the Muscat-like qualities of the Torrontés varieties meant that a relationship to Muscat of Alexandria had been expected, the presence of Mission or Criolla Chica in the pedigree was unexpected to the researchers.

For many years it was believed that the Torrontés of South America was the same variety as the Torrontés grape from Galicia in Spain, also known as Albillo Mayor. This widespread belief was due, in part, to the frequent migration waves of Galician workers that have immigrated to Argentina throughout its history. Indeed, even wine expert Jancis Robinson, noted as much in her 1986 book on the world's grape varieties. However, recent DNA evidence shows that there is probably no direct relationship between the Argentine and Spanish Torrontés varieties and more recent editions of Robinson's wine books acknowledge the new findings.

There is also a less common red wine grape called Torrontés, which is also known under the synonyms Tarrantes and Turrundos.

Torrontés is grown throughout Argentina and its acreage is steadily increasing. Part of its increase in numbers comes from the increase in Argentine wine exportation where the grape has found considerable success in the United States, United Kingdom and abroad but also from a better understanding and identification of the different Torrontés varieties that allow for better accounting of plantings. For most of its history (including into the late 20th century) Torrontés lagged behind Pedro Giménez and Ugni blanc among white grape varieties in Argentina. But by the early 21st century, declining plantings in those two varieties and the growing popularity of Torrontés allowed it to surpass them and become Argentina's most widely planted white variety where it continued to be as of 2008.

The different Torrontés varieties have developed niche in different areas of Argentina. Torrontés Riojano is widely grown in the La Rioja and Salta provinces of northern Argentina and is, in fact, the single most widely planted variety (both red and white) in La Rioja. In Salta, the grape is often planted in high altitude, sandy vineyards that are often more than 1,600 meters (5,200 feet) above sea level. Here, the harsh growing conditions allow the variety to attain high acidity and assertive flavors.
