The town of “Conronbach” was first mentioned in 1142, when a “Conradus de Conronbach” was named in a document dated April 22, 1142. “Grunbach”, in which a pleban is mentioned in 1238, was probably created in the more recent expansion period. The Backnang Abbey (1245), the “von Urbach” (until 1425) and the Schorndorf and Göppingen hospitals were wealthy here. Local nobility is only assured for the 12th century. In 1293, Württemberg took over the protection of the Grunbach estates of the Lorch monastery against the Vogtrecht.
A wine press is attested as early as 1328, and the wine-growing tradition can be proven by a large number of documents. It can also be seen in the three former wine presses on Schillerstrasse.
Grunbach belonged to the Amt or Oberamt Schorndorf and came to the Waiblingen district when it was abolished in 1938. In 1939 Grunbach was classified as a “commercial community and service center”.
On January 1, 1972, the town of Buoch, located above Grunbach, was incorporated into Grunbach.[5] On October 1, 1974, the towns of Geradstetten and Grunbach were finally merged to form today's municipality of Remshalden.
