Heard about dry aging beef but didn’t quite understand what it’s about? In this letter, I’ll tell you about the maturation process and several interesting facts that will help you shine with knowledge at your next dinner party or among steak enthusiasts.
Dry aging of beef (maturation) is a process during which muscle fibers break down, the amount of moisture in the cells decreases, and as a result, there’s a modification and enhancement of the meat’s natural flavor without any marinating.
This occurs naturally, thanks to biochemical processes, provided specific technical conditions are created: the right temperature (from +1 to +3°C), humidity of 75-85%, and constant air circulation inside the refrigeration chamber.
If any of these parameters are violated, nothing good will come of it. For example, if the humidity is too low, the meat will lose too much valuable mass. If there is no air circulation, a crust won’t form on the meat, making it very comfortable for bacteria to settle and multiply on this piece.
Interestingly, some types of fungi also contribute to the aging process, preferring to reside where there’s cold meat and no bacteria nearby (these guys aren’t friends at all). The fungi supplement the meat with enzymes, making it much more aromatic. Almost the same as what happens with cheese. The result is a very pleasant nutty-mushroom aroma.
Maturation usually takes from 3 to 5 weeks. But there are those who age it for more than a year (the record being 420 days).

Dry Aging Of Beef: Everything You Need to Know
A third-generation butcher and owner of the largest meat processing business in America, Pat LaFrieda, wrote a book “Meat: Everything You Need to Know.” It contains a detailed explanation of how beef’s taste and tenderness change depending on the aging duration.
Don’t rush to Google it; we’ve summarized LaFrieda’s words for you 😊:
- “7 days: Collagen has just begun to break down, so the steak won’t yet have the flavors and textures you expect. 7-day aged beef can’t be considered or sold as matured. At this stage, the meat is quite bright, but it will become darker as it ages.
- 3 weeks: The steak has become 10% lighter due to loss of moisture. Water seeps through the top and bottom of the cut, but not from the sides where fat and bones prevent it from escaping. You might have noticed: aged steaks appear more concave because the meat contracts during the process, while the fat only darkens.
- 30 days: These cuts are in the highest demand. Over the past month, they have lost 15% of their weight and have acquired all the flavor and texture qualities inherent to dry-aged meat: the steaks are tender and enticingly aromatic.
- 45 days: The steak starts to have a specific scent, with white streaks (a mix of mold and salt) appearing on it. Over the additional 15 days, the percentage of moisture loss increases only slightly. Important: do not trim all the fat before aging, as the taste of fat changes sooner than the meat itself.
- 90 days: The white crust becomes more pronounced, protecting the meat like the rind protects cheese.
- 120 days: The taste of the steak becomes incredibly intense. Not surprisingly, since over four months, the piece lightens by a third of its original weight. The meat acquires a very unusual taste and naturally commands the highest price, so much so that only a few very expensive restaurants can afford it.”
In a regular store, you won’t find dry-aged steak due to the time and financial costs involved. If you want to try it, you’ll have to look in specialized stores. If you know any others, write in the comments. We found the listed ones through a Google search.
Tip: Only buy it when you’re ready to cook. Putting a piece of aged beef in a regular refrigerator means placing it in suboptimal conditions and negating the effect of the process.
Not everyone will want to pay extra for aging. Recipes often write “to taste.” The same applies here: some may prefer a regular, well-grilled steak over its “matured” version.
Why Pay More: Why is Aged Steak More Expensive?
Dry aging requires premium-quality meat, a lot of time, and sterile conditions. In the world of professional culinary arts, refrigeration cabinets are used. Temperature, humidity, and air flow regulation, along with the absence of bacteria, allow the meat to dry correctly and prevent it from spoiling.
Considering this ↑ and the associated costs, it’s quite clear: aged steak cannot cost the same as fresh, and the longer the aging period, the higher its price.
Can You Dry Age Meat at Home?
Yes, but it takes a lot of work.
There are guides on the internet for dry aging beef at home. Some authors even claim that regular refrigerators are suitable for aging, as long as you wrap the meat in several layers of cheesecloth. But what do professionals say about this?
We can age steaks at home only if our refrigerator allows us to regulate temperature and humidity (it has systems for “drying” the air). In short, a regular household fridge won’t suffice. LaFrieda says that drying meat ourselves is a difficult task and not worth our time.
Why Can’t It Be Done in a Regular Fridge?
Because during the dry aging process, the following must be excluded:
- Regular opening and closing of the door → inconsistent temperature and humidity → dangerous growth of bacteria;
- Presence of any other products → the steak will absorb the smells of everything that’s in it or has been in it for some time.
Tips for Home Dry Aging
- Start Small: If you’re new to dry aging, start with a smaller cut of meat and a shorter aging period.
- Monitor Temperature: Whether using a UMAi Dry bag or a specialty fridge, ensure your beef is stored at a consistent temperature.
- Experiment with Aging Times: Different cuts of beef can benefit from varying aging times. Start with the recommended 3-5 weeks and adjust based on your taste preferences.
- Post-Aging Care: After aging, trim away the dried outer layer of the meat to reveal the tender, flavor-rich beef inside.

When it comes to aging meat, especially for beginners, certain common mistakes can occur. Here are some of the most widespread errors to be aware of:
- Incorrect Temperature: One of the critical factors in aging meat is maintaining the correct temperature, typically around 34-38°F (1-3°C). Too high a temperature can promote bacterial growth, while too low can halt the aging process.
- Inadequate Humidity Levels: Proper humidity (around 75-85% for dry aging) is crucial. Too much humidity can lead to mold growth, while too little can cause the meat to dry out excessively.
- Poor Air Circulation: Aging meat requires good air circulation to prevent moisture buildup and ensure even drying. Lack of circulation can lead to inconsistent aging and potential spoilage.
- Not Allowing Enough Time: Patience is key in aging meat. Rushing the process won’t give the enzymes enough time to break down the muscle fibers, which is essential for that tender, flavorful result.
- Using Low-Quality Meat: The aging process can’t compensate for poor-quality meat. Always start with high-quality, fresh cuts for the best outcomes.
- Improper Cleaning and Sanitation: Aging meat in an unclean environment can introduce harmful bacteria. It’s essential to keep all tools, surfaces, and the aging environment clean and sanitized.
- Ignoring Meat Condition Post-Aging: After aging, the meat’s exterior, known as the pellicle, needs to be trimmed off before cooking. Neglecting this step can result in a tough and unpleasant texture.
- Failure to Monitor and Adjust: Regularly checking on the meat during the aging process is crucial. Adjustments may need to be made to temperature, humidity, or air circulation to ensure optimal aging conditions.
- Over-Aging: Aging meat for too long can result in overly strong flavors and a hard texture, which may not be palatable to everyone.
- Ignoring Personal Taste Preferences: It’s important to remember that aging meat changes its flavor and texture significantly. What is perfect for one person may be too intense for another. Tailoring the aging time to personal taste preferences is key.
Avoiding these common mistakes can significantly enhance the quality of aged meat, whether you’re a beginner or an experienced enthusiast.
Conclusion
Whether you choose the simplicity of UMAi Dry Aging Bags or the sophistication of a specialty dry aging fridge like the SteakAger, dry aging beef at home can be a deeply rewarding culinary venture. Each method offers its unique benefits, catering to different levels of expertise and commitment. By selecting the approach that best fits your needs, you can enjoy the unparalleled taste and texture of dry-aged beef right from your own kitchen.
