Where are the best vineyards in Alsace typically located?

The best vineyards in Alsace are typically located on steep east or southeast-facing slopes. This positioning is crucial as it maximizes sun exposure for the vines, allowing them to ripen fully while also benefiting from the protection these slopes offer against cold winds. The orientation also helps to capture the morning sun, which can help in reducing the risk of frost by warming the vine early in the day. Furthermore, these steep slopes facilitate good drainage, which is beneficial for vine health, as excessive moisture can lead to diseases.

In contrast, flat plains may not offer the same level of sun exposure or drainage benefits, making them less favorable for high-quality wine production. North-facing slopes would receive less sunlight overall, which can impede the ripening process of the grapes, particularly in a region that has a cooler climate like Alsace. Caves, while they might play a role in certain aspects of winemaking or storage, do not serve as vineyard locations and therefore do not contribute to the quality of grape growing in the region.
