When it comes to dry-aged steaks, there’s often a lingering question: should they smell? The answer is not a simple yes or no. Dry-aging is a process that involves allowing the natural enzymes in the meat to break down the proteins and fats, resulting in a more complex and concentrated flavor. However, this process also involves the growth of microorganisms, which can produce compounds that give off a strong, pungent aroma.
Understanding the Dry-Aging Process
To understand why dry-aged steaks might smell, it’s essential to grasp the basics of the dry-aging process. Dry-aging involves storing the steak in a controlled environment, typically between 34°F and 39°F (1°C and 4°C), with a relative humidity of 30-50%. This environment allows the natural enzymes in the meat to break down the proteins and fats, resulting in a more tender and flavorful steak.
During the dry-aging process, the steak will typically lose around 10-20% of its weight due to moisture loss. This concentration of flavors and textures is what makes dry-aged steaks so prized by steak enthusiasts. However, the dry-aging process also involves the growth of microorganisms, such as bacteria and mold, which can produce compounds that give off a strong aroma.
The Role of Microorganisms in Dry-Aging
Microorganisms play a crucial role in the dry-aging process. As the steak ages, the natural bacteria and mold on the surface of the meat begin to break down the proteins and fats. This process produces compounds such as lactic acid, acetic acid, and other volatile organic compounds (VOCs) that contribute to the characteristic flavor and aroma of dry-aged steaks.
However, the growth of microorganisms can also produce compounds that give off a strong, pungent aroma. For example, some types of bacteria can produce trimethylamine (TMA), a compound that has a strong, fishy or ammonia-like odor. Other microorganisms can produce compounds with a strong, earthy or moldy aroma.
The Impact of Microorganisms on the Aroma of Dry-Aged Steaks
The type and amount of microorganisms present on the surface of the steak can significantly impact the aroma of the dry-aged steak. For example, steaks with a higher concentration of bacteria may have a stronger, more pungent aroma, while steaks with a higher concentration of mold may have a more earthy or umami aroma.
However, it’s essential to note that not all microorganisms produce compounds with a strong aroma. Some microorganisms, such as those in the genus Lactobacillus, can produce compounds that contribute to a milder, more pleasant aroma.
The Science Behind the Smell of Dry-Aged Steaks
So, why do dry-aged steaks smell? The answer lies in the chemistry of the compounds produced by the microorganisms during the dry-aging process. As mentioned earlier, microorganisms can produce a range of compounds, including VOCs, that contribute to the aroma of dry-aged steaks.
One of the key compounds responsible for the smell of dry-aged steaks is TMA. TMA is a naturally occurring compound that is produced by the breakdown of trimethylamine oxide (TMAO) by bacteria. TMAO is a compound found in the flesh of animals, and it’s particularly high in fish and seafood.
However, TMA is not the only compound responsible for the smell of dry-aged steaks. Other compounds, such as lactic acid and acetic acid, can also contribute to the aroma of dry-aged steaks. These compounds are produced by the breakdown of sugars and other carbohydrates by microorganisms.
The Role of Enzymes in the Breakdown of Proteins and Fats
Enzymes also play a crucial role in the breakdown of proteins and fats during the dry-aging process. Enzymes such as proteases and lipases break down the proteins and fats in the meat, resulting in a more tender and flavorful steak.
However, the breakdown of proteins and fats can also produce compounds that contribute to the aroma of dry-aged steaks. For example, the breakdown of proteins can produce compounds such as glutamates, which have a savory, umami flavor.
The Impact of Aging Time on the Aroma of Dry-Aged Steaks
The length of time that a steak is aged can also impact its aroma. Generally, the longer a steak is aged, the stronger its aroma will be. This is because the microorganisms have more time to break down the proteins and fats, resulting in a more concentrated flavor and aroma.
However, it’s essential to note that there is a limit to how long a steak can be aged. If a steak is aged for too long, it can become over-ripe and develop an unpleasantly strong aroma.
What to Expect from a Dry-Aged Steak
So, what can you expect from a dry-aged steak? A well-aged dry-aged steak should have a rich, complex flavor and aroma. The aroma should be intense, but not overpowering, with notes of earthy, umami, and savory flavors.
However, it’s essential to note that the aroma of a dry-aged steak can vary depending on the type of steak, the aging time, and the microorganisms present. Some dry-aged steaks may have a stronger, more pungent aroma, while others may have a milder, more pleasant aroma.
How to Store and Handle Dry-Aged Steaks
To get the most out of your dry-aged steak, it’s essential to store and handle it properly. Here are a few tips:
- Store the steak in a cool, dry place, such as a refrigerator.
- Keep the steak away from strong-smelling foods, as the steak can absorb odors easily.
- Handle the steak gently, as rough handling can damage the meat and affect its flavor and aroma.
How to Cook a Dry-Aged Steak
Cooking a dry-aged steak can be a bit tricky, but with a few tips, you can bring out the best in your steak. Here are a few tips:
- Cook the steak to the right temperature. A dry-aged steak should be cooked to at least 130°F (54°C) for medium-rare.
- Use a hot skillet or grill to sear the steak. This will help to lock in the flavors and aromas.
- Don’t overcook the steak. A dry-aged steak can become tough and dry if it’s overcooked.
Conclusion
In conclusion, a dry-aged steak should have a rich, complex flavor and aroma. The aroma should be intense, but not overpowering, with notes of earthy, umami, and savory flavors. However, the aroma of a dry-aged steak can vary depending on the type of steak, the aging time, and the microorganisms present.

What is dry-aging and how does it affect the smell of steak?
Dry-aging is a process where beef is allowed to age in a controlled environment, which concentrates the flavors and tenderizes the meat. During this process, natural enzymes break down the proteins and fats, resulting in a more complex flavor profile and a tender texture. As the meat ages, it develops a stronger, more pungent aroma due to the growth of mold and the breakdown of proteins.
The smell of dry-aged steak can be intense and may be off-putting to some people. However, this smell is a natural result of the aging process and is not necessarily a sign of spoilage. In fact, many steak connoisseurs believe that the stronger the smell, the more flavorful the steak will be. However, it’s essential to note that there is a fine line between a strong, pungent smell and a smell that indicates spoilage.
Why does dry-aged steak smell so strong?
Dry-aged steak smells strong due to the growth of mold and the breakdown of proteins during the aging process. As the meat ages, it develops a natural crust on the outside, which is home to a variety of microorganisms, including mold and bacteria. These microorganisms feed on the proteins and fats in the meat, breaking them down and producing compounds with strong, pungent aromas.
The type of mold that grows on dry-aged steak can also contribute to its strong smell. Some types of mold, such as the white mold that grows on many dry-aged steaks, have a mild, earthy aroma, while others, such as the blue-green mold that grows on some dry-aged steaks, have a stronger, more pungent smell. The type of mold that grows on the steak can affect its overall aroma and flavor.
