Aging is the process of holding meat after slaughter so its own enzymes can tenderize it, and there are two methods. For dry aging, meat is left uncovered in a room with controlled humidity and temperature; it loses water, forms a crust on the outside, and develops a more concentrated flavor. For wet aging, meat is held in a vacuum-sealed package; it does not lose water, its flavor remains milder, and the product is considerably less expensive. The difference comes down to flavor intensity and price.
Meat is not tender immediately after slaughter. In the first hours, the muscles contract and stiffen, and a piece in this state will be tough to chew no matter how well it is cooked. Over the following days, the meat’s own enzymes slowly break down connective tissue and muscle proteins; the meat relaxes and flavor compounds accumulate. This process takes place at just below 4°C / 40°F and takes weeks. Meat bought from a butcher is expected to have already been aged for a while; aging meat at home is a separate undertaking because it requires equipment and continuous monitoring.
For dry aging, meat is hung in a cabinet with airflow and controlled humidity. The outside dries and forms a dark crust, which is trimmed and discarded before serving. During this time, the meat loses a significant portion of its weight as water, so there is less meat left and it costs more. In return, the flavor becomes concentrated and develops a distinctive, nutty aroma. The aging period ranges from 21–45 days; the longer it ages, the more pronounced the aroma becomes, and after a point it may not suit everyone’s palate.
Wet aging means leaving meat in its own juices in a vacuum-sealed bag, and most meat sold in grocery stores goes through this process. Because the bag prevents water from evaporating, there is almost no weight loss, which is the main reason the product stays inexpensive. The enzymes still work, so the meat becomes tender, but it does not develop the same concentration as dry-aged meat and its flavor remains milder. The period is usually 7–21 days. The slightly sour smell when the bag is opened is a known side effect of this method and dissipates within a few minutes. If the smell lingers, or the surface feels sticky, tacky, or slimy, the meat has spoiled and should not be used.
These 2 methods do not work for every cut of meat. Dry aging makes sense for thick, well-marbled loin cuts; when a thin piece dries out, there may be no edible meat left after the crust is trimmed away. Wet aging works with almost every cut. At a butcher shop, dry-aged meat can be identified by its dark red color and dry-looking surface when cut. Whichever type you buy, the cooking rule does not change: color is not a doneness test, and all cuts should be cooked to 63°C / 145°F and rested for at least 3 minutes.
Trying to dry-age meat at home is not recommended because the process depends on controlling temperature, humidity, and airflow at the same time; meat left uncovered in an ordinary refrigerator is not aging, it is only drying out, and uncontrolled changes begin on its surface. Instead, asking a butcher for aged meat is both safe and practical. When buying it, ask how many days the meat was aged and expect a clear answer; a counter that does not know the aging time probably has not done the process at all. For vacuum-sealed products, the date on the package already gives the duration.

Marketteki vakumlu et zaten yaş dinlendirilmiş oluyormuş. Poşet açılınca gelen o hafif ekşi koku bununla mı ilgili?
Evet, poşet açıldığında gelen hafif metalik ekşi koku normaldir ve et birkaç dakika havayla temas edince geçer. Geçmiyor, üstüne keskinleşiyorsa o başka bir konudur.
