Torrontés is a white Argentine wine grape variety, 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 Gewurtztraminer wines. The least aromatic, and least widely planted, is Torrontés Mendocino with the aromatics and plantings of Torrontés Sanjuanino falling in between.
