I read that report also. I thought it was interesting that “There are no published studies that have compared the effects of relative humidity levels on dry-aged beef, and it appears the studies in this area have used a relative humidity of approximately 80% with a considerable range around that number.”
Excerpt- Once a piece of beef has been selected as adequate for dry aging, the beef is hung in a refrigerated room with temperatures maintained between 32 and 39 degrees Fahrenheit or 0 to 4 degrees Celsius and humidity is controlled to ensure freshness. The preferred humidity setting varies from 50 – 85%, according to individual preference, but usually is set closer to 60%. The recommended air flow is 0.5 – 2 m/s or 1.6 – 6.6 ft/s. to ensure optimal weight and trim loss during the aging process. Once you learn how to age steak properly you will know how imperative it is to control the temperature, humidity, and air flow.
And another one- Beef that makes the cut is hung in temperature and humidity controlled lockers for anywhere from two weeks to two months. Temperature and humidity are vital factors in dry aging. Freezing temperatures stop the enzymes responsible for tenderization from working their magic, but the warmer the locker is, the more risk there is for the meat to spoil. Humidity, which can increase or reduce the speed of moisture loss, factors into the amount of useable meat at the end of the aging period. Humid air can slow moisture loss, but also creates an environment more hospitable to unwanted microbes. The sweet spot for temperature and humidity usually falls between 0 and 4 degrees Celsius and 50 to 85% humidity, but it can vary depending on the vendor.
I’m still hoping I’ll hear back from one of the three I reached out to in New York. Would definitely cut down on the trial and error period. Hopefully!
Thanks for the input daveomak!
