Christoph Tyrell, who owns and runs the estate, exclusively exploits the Karthauserhofberg, one of the Ruwer's great vineyards. Situated in Eitelsbach, the estate dates back to the time of Carthusian monks and thanks to the dedication and hardwork of the Tyrells since purchasing the estate in the 1980s, is now one of Germany's most highly regarded. The wines are intense, slatey and boast the poise and raciness found in the wines of the Mittel Mosel but perhaps in a slightly broader, earthier style. Christoph ferments the wines in stainless steel which he believes slows down fermentation and results in wines with cleaner and clearer flavours.
