Technical innovation

After the purchase of the property by Carl Ferdinand Freiherr von Stumm-Halberg, substantial investment turned it into a model estate.

The construction of a large turbine, powered by the waters of the Ruwer, provided electricity to all parts of the estate, from the agricultural sectors to the cellars. Copper cables as thick as a man’s arm were laid in deep channels throughout the estate in order to provide a supply of the new energy. Depending on the weather, however, the water levels in the Ruwer fluctuated: wet summers gave a plentiful supply of water to the turbine blades, so that the high voltage provided good machine performance and bright light in the buildings. Sadly, the quality of the wine in these years was mostly modest. In very dry years the turbine’s revolutions were noticeably slower, the light was feeble and unreliable, but in the autumn you could mostly look forward to a very good year.

It was only at the end of the 60s that the Grünhaus turbine manager retired, electricity generation was abandoned and in future you could no longer gauge the quality of the coming vintage by the brightness of the lights.
