What are the two white grape varieties allowed in the Hermitage region?

In the Hermitage region, which is situated in the northern Rhône Valley of France, the two white grape varieties authorized for the production of white wines are Marsanne and Roussanne. These varietals are traditional to the region and are celebrated for their ability to produce complex and age-worthy wines.

Marsanne is known for its full body, rich texture, and flavors that can include stone fruits and almonds. Roussanne, on the other hand, generally adds aromatic complexity and acidity to blends, showcasing floral and herbal notes alongside citrus and peach-like characteristics. Together, they create wines with depth, balance, and potential for aging.

The other choices presented are not correct because they do not reflect the varietals permitted in Hermitage. Chardonnay and Viognier, while both significant in other regions, are not found in the Hermitage AOC. Sauvignon Blanc and Muscat are also not part of the authorized grapes in Hermitage; rather, they are more typical in regions like Bordeaux and the southern Rhône, respectively. Lastly, Pinot Blanc and Pinot Gris, while they are known in regions such as Alsace, do not play a role in the Hermitage white wine profile.
