Sonor Wines is the brainchild of Viennese food and wine expert – and horn player – Markus Bachmann. His pioneering method exposes wine to music during fermentation – a process that, according to its inventor, refines the finished product. Bachmann explains that once in the steel fermentation tanks, a biochemical reaction is set in motion by the tiny vibrations triggered by sound waves. He also believes that varieties of wine which have been treated using this technique contain less sugar, have a fuller flavor and are more drinkable. Different genres of music are also said to give the wines different characteristics. In principle, this means any type of music can be used, from symphonic works to hunters’ classics, waltz and polka melodies and even Viennese folk sounds like Schrammelmusik. The process has been put to the test in Vienna’s Wienbauschule Klosterneuburg on a GrÃ¼ner Veltliner, but no reports yet on whether it bears similar results to playing Mozart in utero. However, a number of leading growers have taken the plunge and put the new approach into practice, including Vienna-based producers Peter Uhler and Franz-Michael Mayer, who have already bottled the first generation. If music be the food of wine, I say, play on.
