 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.
