https://en.wikipedia.org/wiki/Beef_aging
Beef aging is a process of preparing beef for consumption, mainly by breaking down the connective tissue.
Dry-aged beef is beef that has been hung or placed on a rack to dry for several weeks. After the animal is slaughtered and cleaned, it is hung as a full or half carcass. Primal (large distinct sections) or sub primal cuts, such as strip loins, rib eyes, and sirloin, are placed in a refrigerator unit, also known as a "hot box". This process involves considerable expense, as the beef must be stored near freezing temperatures. Subprimal cuts can be dry aged on racks either in specially climate-controlled coolers or within a moisture-permeable drybag. Moreover, only the higher grades of meat can be dry aged, as the process requires meat with a large, evenly distributed fat content. Because of this, dry-aged beef is seldom available outside of steak restaurants and upscale butcher shops or groceries. The key effect of dry aging is the concentration and saturation of the natural flavour, as well as the tenderization of the meat texture.

Месото е добито само в една лицензирана кланица, с проследяване на произхода на всяка една опаковка. След това е отлежало (узряло) минимум 21 дни при контролирани условия за добиване на повече крехкост и вкус. В месото ни няма никакви добавки и никаква вода.

Добре отвисялото, добре узрялото говеждо месо има два показателя, за да бъде разпознато - първият е тъмен червено-кафяв цвят, вторият е, че при натиск с пръст се образува вдлъбнатина, която много бавно или почти изобщо не си възвръща формата.
