The banker Carl Gunderloch established Weingut Gunderloch in 1890 at Nackenheim in the Rheinhessen. Since 1989 it has been run by his great-great-grandaughter Agnes HasselbachUsinger and her husband, Fritz Hasselbach.

The estate has nearly 13 hectares of vineyards, including an almost monopole position in the world-famous Rothenberg. This is situated on one of the steepest slopes on the Rhine and is classified as one of only 3 Grand-Cru `A` vineyards in all of Rheinhessen. Everything from Kabinett through to Trockenbeerenauslese is produced from the Rothenberg - average yields are 45hl/ha, which are amongst the lowest in Germany and result in wines of concentration and intensity.

These wines are models of elegance, subtlety, depth and balance.
