Workers had to reorient themselves and take on new unfamiliar jobs. This changed Dielheim in the 1950s and 1960a to a commuter town. Only the creation of Dielheim's industrial and commercial district led to the creation of its own companies, so that workers could once again find jobs in town. Today's Dielheim is known as a wine-growing region with 77 hectares of surrounding grape fields. "Dielheimer Teufelskopf" is known by wine lovers throughout Germany. In 1972 Horrenberg joined the municipality of Dielheim.
