Ahr Valley, small wine region in the Ahr river valley south of Bonn in Germany, producing mainly red wine, with Pinot Noir its flagship, despite being Germany’s northernmost wine region. Large, rich centres of population nearby provide a ready market. 

Terroir: The Ahr river is a western tributary of the Mittelrhein (Middle Rhine), just south of Bonn. The vineyards occupy steep slopes overlooking the river for around 10 miles (16 km).

Vineyard area: ha (1,000 acres). Two-thirds is Spätburgunder (Pinot Noir), Portugieser and other red grapes. One third is Riesling, Müller-Thugau and Kerner. 

Grosslage (1): Klosterberg.

Wines: Red wines are predictably pale and thin given the latitude, and are hence often made distinctly sweet.
