Through the elevations of the Rhine Rift around Birkweiler, Albersweiler and Frankweiler geologically really old types of soil came to the top. That's why the most famous old part of Kastanienbusch is well known for the really rear types of red slate. This type of soil developed 280 Million years ago. It contains granite, slate and melaphyre. Through the high iron content the soil is dark red and is a really good heat reservoir. Kastanienbusch is the only vineyard side with red slate in the whole Pfalz region.

"This smells like breaking open a beautifully ripe passion fruit! The palate of this great dry riesling has a very sleek silhouette, but an enormous amount of complex minerality (think every shade of rock from red to black) packed into it. Like a tight rosebud that needs time to unfurl its tightly folded beauty. From biodynamically grown grapes with Respektcertification. Drinkable now, but best from 2024."
