As wine is more than 80% water, we at La Vigne play classical music in our barrel cellar, 24 hours a day, 7 days a week, believing that music will change our maturing wines in a harmonic way. Because of a 56 dB loss on its way into the oak barrels, the music has to be played very loud, at about 100 dB(SPL). The speed of sound in our wine is around 1480 m/sec, four times higher than in air, which helps distribute the pressure-waves inside the barrels.
