The vineyards are located on the steep slopes of Bernkastel, Liesertal, Wehlen, and Ürzig. A large portion of the area is planted with ungrafted and very old vines. Each vineyard has its own unique characteristics. Each soil type, combined with the location and its associated microclimate, produces a unique wine with a distinct character. The winery is certified organic.
Slate is the classic location for Riesling. There are many good vineyards. However, the undisputed masterpiece is steep slopes. Only these have the microclimate and soil that transform a good Riesling into a great Riesling. Steep slopes are a practice and a desired feature—the more the better.
