Which of the following is NOT listed as a sub-appellation of Niagara-on-the-Lake?

Vinemount Ridge is not recognized as a sub-appellation of Niagara-on-the-Lake. The appellations of Niagara-on-the-Lake include Four Mile Creek, St. David's Bench, and Niagara Lakeshore, which are all established designations identifying specific regions within the Niagara-on-the-Lake wine region. These sub-appellations are notable for their unique terroirs and contributions to the styles of wine produced in the area.

In contrast, Vinemount Ridge is actually associated with the broader Niagara Escarpment wine region, indicating it is part of a different geographic classification rather than being specifically tied to Niagara-on-the-Lake. Understanding the structure of these sub-appellations is crucial for recognizing the diverse wine production areas within the Niagara region and how they each contribute to the characteristics of the wines they produce.
