Fritz Haag whose family has been engaged in viticulture at Brauneberg since 1605, is the town's most important proprietor. Using traditional cellar techniques and careful, selective harvesting he produces Brauneberger wines that have power and elegance with fine Riesling fruit and a subtle slate background in balance with generous fruity acids. One of his ancestors was a co-founder of the Brauneberger-Juffer-Sonnenuhr vineyard site. At present, the Fritz Haag estate owns the largest and best portion of this vineyard. All sites are 100% Riesling.
