We understand that an Austrian winemaker, a certain Markus Bachmann (perhaps the clue is in the name?) has invented a special speaker that exposes fermenting grape juice to classical, jazz or electronic music. The sound waves, he claims, produce better-tasting wine. Aside from the fact that he is a former French horn player (although brass players are normally reputed for their beer prowess) he says the wines seem to get more fruity - as, it must be admitted, many of us do when we listen to music.
Mr Bachmann has teamed up with six other Austrian wine growers to produce so-called Sonor Wines, priced - and maybe this is the clue - north of 19 euros a bottle and including a 2010 pinot blanc "infused with Mozart's 41st Symphony". Whilst the sound waves may indeed have an effect on the fermentation, the waves created by the price might be of a different kind - especially when across the Atlantic a Mexican producer also claims to use music, but he says he cannot be sure any of it works but is completely confident that it does ..er...no harm.
