Do not lump the three varieties together.
Argentina’s INV recognizes three varieties of Torrontés: Riojano, Sanjuanino, and Mendocino. This course focuses on Riojano. When a label or resource states only Torrontés, check the producer’s information to clarify the exact variety.
Distinguish parent varieties from the current ingredients
According to DNA analysis by Wines of Argentina, Torrontés Riojano is described as a variety crossbred from Muscat of Alexandria and Listán Prieto. Knowing the parent varieties is different from blending both grapes into a wine. Do not confuse the genetic history of a grape with its use as a blend in the final product.
Even with a rich aroma, the wine can be dry
Torrontés Riojano includes fragrant dry whites as well as sweet or sparkling styles. Even if aroma suggests sweetness, the palate does not necessarily match. In comparisons, confirm aroma intensity, residual sugar, and the presence/absence of bubbles separately, and avoid generalizing from a single tasting.

Which individual varieties are covered in this course?
INV distinguishes three varieties as Torrontés. In this course, we cover Torrontés Riojano. Do not count all three as the same variety just because they share the name. If the label is abbreviated, check the exact grape name in producer information.
Does the notation of hybrid parents mean a blend of two grape varieties?
The hybrid parent refers to the background in which the variety was created. It does not mean that the parent variety itself is included in the wine. If the ingredient is Torrontés Riojano, record that as a single variety; check the blend column separately to confirm blending.
Is floral-scented Torrontés always sweet?
Wines of Argentina presents a wide range of styles, including aromatic dry whites. The intensity of aroma is not the same as sweetness from residual sugar. During tastings, record the aroma first, then check for sweetness and acidity, and if necessary, confirm residual sugar by referring to the technical analysis.
