Which term refers to the blend of varieties allowed in Cote Rotie?

The blend of varieties allowed in Côte-Rôtie, a prestigious appellation in the northern Rhône Valley, is specifically defined by the AOC regulations, which permit the inclusion of specified grape varieties. In Côte-Rôtie, the primary grape variety is Syrah, but winemakers are allowed to blend in a small percentage of Viognier, a white grape. This blending practice highlights the unique character of Côte-Rôtie wines, as the combination of these varieties creates complexity and aromatic qualities.

Referring to the term "permitted varietal blend" accurately captures this regulatory allowance, signifying the official acceptance of blending specific varieties in the production of Côte-Rôtie wines. This term emphasizes that the blend is not random or arbitrary but governed by standards that ensure quality and authenticity in the wine.

In contrast, a single varietal wine would imply that only one type of grape is used, which isn't the case here. A field blend typically refers to grapes grown and harvested together, often without attention to their varietal distinctions. While “Viognier and Syrah blend” directly names the varieties involved, it lacks the broader applicability that "permitted varietal blend" encompasses, which includes the context of regulatory approval and stylistic intention behind
