A lot of flowery adjectives get tossed around when the topic of dry-aged beef comes up. Some food writers call the process “artisanal.” To others, it’s “old-world” and “earthy.” Those descriptors may be enough to entice intrigued diners to make the leap — and spend the extra $$$ for a dry-aged option — but they fail to explain what’s actually happening during the process, and why dry-aged beef is truly a delicacy.

Let’s start with the basics of aging

Even in restaurants claiming to have “fresh” beef, most has been aged to some extent. Wet-aged: beef that’s been stored inside a vacuum package in a cooler for a few weeks, allowing the naturally-occurring enzymes within the meat to break down muscle fibers and create tenderness. With wet aging, what goes into a bag is pretty much what comes out of the bag, only more tender. Know that this enzymatic activity, however, occurs regardless of the environment — wet-aged, dry-aged or otherwise. So, to a certain extent, the longer beef ages in general the more tender it will become.


Now let’s talk about dry aging

This is what dry aging looks like. Beef just hanging out on a shelf inside a dry-aging cooler getting crusty. Better bring some popcorn, it’s gonna be a long viewing. Three things need to happen inside the meat during the dry-aging process:

#1: Time.

Allow time for the naturally-occurring enzymes to do their thing, thus making the beef more tender. If this is new information to you, then you just skipped the 249 words preceding this. Shame on you.


#2: Dehydration.

Unlike its wet-aged brethren, confined to an air-tight bag, dry-aged beef is free to explore its environment, including the encouraged evaporation of moisture from within the cut. And, while this is responsible for much of the darkening of its crust, what’s left inside is intense, beefy flavor, concentrated from the dehydration. The need to trim off that crust before cooking means significant yield loss, however, a big reason why dry-aged beef is so pricey.


#3 Mold.

This is the trickiest part of dry-aging, and the key difference between truly dry-aged vs. just dehydrated. Folks may not hold degrees in any kind of mold-related science, but it’s generally understood that in different parts of the country there are different kinds of molds. Despite their reputation, molds truly bring the funk; they are the critical element to the dry-aging process because they impart certain flavors. So, depending on your zip code, those molds and the flavors they create are going to be different.


New York City is the dry-aging capitol of the world, but Los Angeles has its own level of funk. In between is the CAB Culinary Center in Ohio, where meat scientist Dr. Phil Bass says, while the process of dry-aging has been going on for centuries, we’re still, continually learning more.

It wasn’t too long ago that the food industry — and health inspectors fearful of molds — nearly science’d itself out of this incredible process. Approved aging techniques, then designed to stop mold rather than promote it, may still be limiting the addition of other desirable flavors.


Fortunately, the pendulum swings back toward tradition and we can find more dry-aged beef today. Even high-end grocery stores, like Market District in Ohio and Pennsylvania, have added coolers specifically for dry-aging.

While “artisanal,” “old world” and “earthy” may be correct, you now know exactly why dry-aged beef is a delicacy worth trying.
