The Holsten subsidiary Hansa-Brunnen already owns 45% of Heemann. The full acquisition of the company will make Holsten the second largest mineral water producer in Germany after Leisslinger.

Heemann's brands include mineral water under the names Werretaler, Iris-Quelle, Wildsberg-Quelle or Quintus Quellwasser. Its total output reached 2.3m hectolitres in 2002.
