The Sornziger Wilden range includes 24 varieties of wild fruit spreads. Volker and Hannelore Umbreit are the sole suppliers of some of these in Germany. Their work is guided by the principle of "protecting by using". The fruit is harvested by hand exclusively from the company's own trees and processed directly on site. No flavor additives, colorings, flavor enhancers or spices are used. On guided tours through the wild fruit display area in the Marienthal monastery in Sornzig, created by Hannelore and Volker Umbreit, interested parties can be transported into the world of wild fruits, experience multimedia presentations or get to know the Sornziger Wilden range during a tasting.
