Last fall, Swiss researchers exposed nine wheels of Emmentaler in an aging cellar to various types of music: classical (Mozart’s Magic Flute), rock (Led Zeppelin’s “Stairway to Heaven”), techno (Vril’s “UV”), hip-hop (A Tribe Called Quest’s “Jazz (We’ve Got)”) ambient music (Yello’s “Monolith”), and, as controls, steady high, medium and low tones and silence. All were on nonstop loops, with mini-transducers transmitting the sounds directly into the cheese wheels. After six months, the wheels were taken out and taste-tested — and here are the results.
