The thin slate stones of our vineyards in the Mosel River Valley are a critical factor in crafting a Riesling of exquisite balance. So precious are these stones that those which slip into the river are carefully carried back up the treacherously steep vineyard slopes and returned to place. Reflecting and retaining heat, the slate is essential to ripening grapes in this cool climate, developing the wine’s fresh peach, crisp lime, and subtle mineral flavors.
