Leitz’s estate vineyards lie entirely on the westernmost part of the Rheingau on the Rüdesheimer Berg—a steep, south-facing hillside of extremely old slate and quartzite—planted entirely to riesling, encompassing the Grand Crus of Schlossberg, Rottland, and Roseneck. Leitz trains his vines in a single-cane, cordon system to improve the quality and character of the fruit, differing from the majority of Rheingau growers where the practice has long been to prioritize yield via a double-cane system. Johannes is a firm believer that the crucial work of the vigneron takes place in the vineyards. Focused on farming as sustainably as possible and working by hand, the grueling hours of labor on the ultra-steep slopes allow these ancient vineyards to reach their maximum potential.
