Hirschquelle VITAL comes from the depths of the Black Forest. A healing water is pumped from it, which is sold by Mineralbrunnen Überkingen-Teinach AG under the brand name Hirschquelle. According to the manufacturer, it is suitable for stimulating digestion, for promoting the function of the stomach and intestines. The Hirschquelle was drilled in 1841 on the so-called Hirschwiese. The depth of the well was 88 feet and 2 inches. Originally in Teinach there was an iron-rich, weakly alkaline spring called the Dintenquelle and three alkaline acidulous springs, namely the spring in the roof box, the spring in the middle box and the source in the wall box. These sources were not sufficient for the growing spa business, so a drilling program was started. The Laubenquelle was drilled in February 1839, and the Wiesenquelle in May. In 1841 the source of the stream was drilled. In the 1970s, the Hirschquelle was tapped with further drilling. These wells are referred to as Hirschquelle II and Hirschquelle III .
