Which of the following is one of the two most famous village appellations of the Maconnais?

Pouilly-Fuissé is indeed one of the two most famous village appellations in the Mâconnais region. This appellation is particularly renowned for its high-quality white wines made from Chardonnay. The vineyards are situated on the slopes of the Saône Valley, where the climate and soil conditions are favorable for producing wines that reflect the characteristics of the region, often displaying ripe fruit flavors and a certain richness.

In addition to Pouilly-Fuissé, the other major village appellation often mentioned alongside it is St-Véran. Both are known for their premium wines, and Pouilly-Fuissé specifically has a wider recognition, often regarded as a flagship of the Mâconnais.

The other choices, while notable in their own regions, do not belong to the Mâconnais. Montagny, for instance, is also a white wine appellation but is less celebrated than Pouilly-Fuissé and St-Véran. Morgon and Chiroubles are both village appellations located in the Beaujolais region, primarily associated with Gamay wines, which further distinguishes them from the Mâconnais context.
