My Dad told me if you want tender beef, put a steer in a stall/pen where he has enough room to eat and lie down.That’s why Kobe beef is a couple hundred $$ per pound.

- The first is that the cows are given beer to induce appetite.
- The second is that they are massaged daily, sometimes with sake (Japanese rice wine), as a proxy for exercise in the tight living quarters and to further accentuate the marbling that Kobe beef is so well known for.
- And the third is that classical music is played to them as a relaxation technique and at feeding time, so they associate the music with eating and hence the music improves their appetite
I got stuck in Tokyo once to airline issues, given a voucher for a room at an upscale hotel and a meal voucher. For dinner Kobe steak was served. It was the most flavorful steak I’ve ever had, almost fork tender.
Exercise firms up (and toughens) the muscles, and burns fat that you want to marble the meat.
