UMAi Dry dry-aging bags imported from the United States are used for dry-aging steaks. This packaging is for steaks of the same size as sirloin or ribeye (preferably a whole steak) and can be stored for 28-60 days. 35 days is recommended. If you want a better and richer taste, use 45/60 days. The aged steak will have a unique and obvious "nutty and cheesy" aroma, and will make your steak more tender and the beef flavor more intense! The function of the bag is to allow moisture to escape and block bacteria. All you need is a refrigerator, no expensive aging equipment worth tens of thousands of yuan is needed. There are three bags in one pack.
