Krumbach is a town in the German state of Bavaria. Since 1831 there has been a very simple, rural spa with a slightly iron-rich spring in the graceful, young Ice Age hilly landscape next to a sawmill and a country inn in Krumbach. Around 1900 the bottling of water started here. In the decades that followed, the fountain system was modernized and expanded several times. The old shallow shaft well was replaced by a deep well and over the decades Krumbach water base was expanded to a total of four wells. After the Second World War, the mineral spring operation in Krumbach was continuously expanded.
