Which is a sub-appellation within the Niagara Escarpment?

The Beamsville Bench is a recognized sub-appellation within the Niagara Escarpment, an important wine-producing region in Ontario, Canada. This area is particularly well-regarded for its ability to produce high-quality cool-climate varietals, such as Riesling and Pinot Noir, owing to its unique microclimate and the influence of the escarpment's geography.

The Beamsville Bench benefits from its elevation, which contributes to good air drainage and helps prevent frost, as well as a moderating effect from nearby Lake Ontario. This combination creates an ideal environment for grape growing, allowing winemakers to cultivate grapes that express the region's terroir effectively.

While Creek Shores, Lincoln Lakeshore, and Vinemount Ridge are also sub-regions within the Niagara wine region, they are not officially classified as sub-appellations within the Niagara Escarpment itself, making Beamsville Bench the correct answer for this question.
