The best vineyards in Germany are indeed typically located on very steep south-facing slopes near rivers. This positioning is crucial for several reasons.

Firstly, the steep slopes allow for better drainage, which helps protect the vines from excess water and reduces the risk of rot. This is particularly important in regions like the Mosel, where the landscape is characterized by steep vineyards overlooking the Mosel River.

Secondly, south-facing slopes are advantageous because they receive maximum sunlight throughout the day. This exposure to sunlight is vital for the ripening of grapes, particularly in a cooler climate like Germany's, where heat units can be limited. The angle of the slope also helps to capture and retain heat, contributing to a more favorable microclimate for grape cultivation.

Finally, proximity to rivers is beneficial as they help moderate temperatures, reducing the likelihood of frost during critical growing periods, and can reflect sunlight onto the vines, enhancing photosynthesis. Together, these features make the steep south-facing slopes near rivers the ideal location for producing high-quality wines in Germany, particularly the famous Rieslings for which the country is known.
