Wine is a product of nature? No. Wine is wrested from nature, is a de-velopment of civilization, the (agri)culture. And by now of the food-industry? Mostly yes. We build a countermovement. Wine as a cultural con-cept. For us this includes – for more then 20 years now – an alcoholic fer-mentation without breeding yeast. The science institute for microbiology of the University of Mainz has investigated microbially fermentation the microbio-logical fermentation process of our spontaneous fermentation and did not find any – officially unavoidable – saccaromyces cerevesiae. Instead they identified unknown acetobacter a variety of microbes as well as two unknown yeasts. Besides they detected two unknown bacterias – before unknown ace-tobacter. Wild yeasts have less power than their artificial brothers. Often our wines have not completed the fermentation process as far as we wanted them to do. Because we learnt at school that cows produce more milk while hearing Mozart than Heavy metal, the idea of a sound installation raised up in the 90ties. Inspired by the aeloic harps in ancient Greece the wind generates a sound in a big panflute which influences on very low frequency even the inner of the barrels the pipes and leaves procreative impulses to the microbes. As a counter-pole groundwater of the Mosel flows through the cellar and comple-tes the energy field between Apollon and Dionysos, between Feng and Shui. In our composition »sound of slate«, not the flow of the water but the blub-bering fermentation noise in the glass tubes builds the opponent to the pan-flutes. An exciting audio experience – something between Soundtrack of Captain Nemo, Gregorian chorales and Tibetan meditation. The CD can be purchased at € 9,50 at the wine estate.
