Location and landscape
The Ahr is one of the 13 officially designated German winegrowing regions and lies in the Ahr valley at the northern edge of the Eifel. The growing area extends along the River Ahr; the largest town is Bad Neuenahr-Ahrweiler. Steep slopes, vineyard terraces and dry stone walls shape the wine landscape.
Climate and soils
The Ahr has a mild climate; in some steep vineyard sites there is a greenhouse-like microclimate. The lower part is open towards the Rhine valley and benefits from the low-lying valley locations as well as the mild Rhine climate. The upper part lies in a sheltered, narrow valley, the microclimatic conditions of which vary depending on the orientation of the river bends. In the lower Ahr valley, deep, fertile loess soils predominate, whereas in the middle Ahr valley schist, volcanic rock and stony soils occur.
Grape varieties and cultivation
In 2024, the planted vineyard area covered 533 hectares. Red grape varieties accounted for 79.3 per cent, white for 20.7 per cent. The Spätburgunder (blue Pinot noir) was the predominant grape variety with 346 hectares, or 64.9 per cent. Other important grape varieties include Frühburgunder (blue Frühburgunder), Riesling, Müller-Thurgau, Portugieser (blue Portugieser), Grauburgunder and Weißburgunder. The Ahr is predominantly a red-wine region; Riesling is the most common white grape variety and is used to make fresh, lively white wines.
Many steep sites are cultivated manually, as access for vehicles and mechanised cultivation is limited. In steep plots, harvest is carried out by hand. On some slopes, monorail rack systems are used to transport workers and equipment. Some northern terraces are so narrow that only three to six vine plants can fit there.
History and wine law
Winegrowing in the Ahr valley dates back to Roman times. Ahr is recognised as a protected designation of origin. Ahrtaler Landwein carries a protected geographical indication. For certain grape varieties and vineyard parcels along the Ahr, German wine law also permits lowering the natural minimum alcohol content below the general threshold value for winegrowing region A.
