In a previous article we explained the way the USDA inspects and grades meat. The top grade is called USDA Prime. It is the highest distinction of quality. It has a high degree of marbling (intramuscular fat) and is VERY flavorful when cooked.
This is why so many famous steakhouses use the word PRIME in their name (that, and a lack of creativity).
In the past, only 2% of all the cattle raised in the US would make this grade. More recently that number hovers between 5% and 7%. There is more beef grading Prime (which is great!!) but it does not mean all of that Prime beef is just as good... just like not all USA Choice is equal.
Prime Grade beef is guaranteed to have excellent flavor, but it does NOT guarantee the other most significant factor that defines a great steak: Tenderness. By the way... this also explains why not all wagyu is the same.
Tough meat cannot be recognized by eye when you are buying at the supermarket. Marbling is not a driving indicator of tenderness (marbling accounts for a mere 10% of the variation in tenderness). Breed and sex also have relatively little effect on tenderness... (atleast when we are looking at Angus, Holstein and Hereford)
This is why paying for things like G1 certification are becoming more and more important to select the best quality of beef.
WHAT MAKES BEEF TENDER?
Now that we have established that marbling does NOT impact the tenderness of beef, we can delve into what does:
All beef in the US is aged (which is why we have the greatest beef industry in the world alongside Japan and Australia). However, not all beef is aged the same.
Beef is initially "aged" right after slaughter, when the carcass is hanged and kept at a certain temperature for 7 and up to 14 days. Getting this right makes a difference.
After the beef is broken into primal pieces, those may also be wet aged, most commonly 7 days... G1 beef is wet aged for 30 days. These extended aging techniques make a difference, but also add a premium to the price of the steak you get at the counter.
(2) Humane Practices: A peaceful sleep.
According to research in Australia and New Zealand, also backed by research in the US, Stress is one of the most important influences on ultimate meat tenderness.
Ideally animals should be rendered unconscious by electrical stunning immediately prior to slaughter, that way the animal passes away peacefully and the muscles do not stress. We work with farmers who follow these standards... but it also adds a premium!!
(3) Age at Slaughter
Younger animals will always be more tender (that is why the cochinillo is so much more tender than a regular pig). As animals get older, the amount of connective tissue (collagen) increases, as that happens the connective tissue becomes resistant to dissolution when cooking. As a result, beef from older animals is less tender.
This is an important point. Older animals will usually have more marbling. Old Dairy Cows can be slaughtered and grade PRIME. Yet they will be significantly less tender than a steer slaughtered at the right age (they will also taste more acid).
This is why you can find "Prime" steaks, that are significantly cheaper than other "Prime" steaks. Beef is a commodity. You cannot cheat price.
Tenderness is heritable. Tender sires have tender calves.
Programs that are known for generating quality tender beef... will have a leg up vs programs that do not. That said, even the most tender meat derived from progeny of the most select of sires can be ruined by stress before slaughter. So a "good" farm, can go "bad" really quick by changing slaughterhouses or getting acquired.
Finally, many new studies are showing the pH of the meat is as important as the marbling…so much so that certain programs are grading on pH only rather than marbling. While marbling is the visually appealing characteristic that gets us drooling, there are many other factors that play into how the steak will perform.
YOU CANNOT CHEAT PRICE
In order to compete in pricing many producers/butchers cut corners to achieve a lower price point. There is nothing wrong with this practice, except when they pretend that they are not.
In order to produce less expensive meat a producer can work with older cattle, which is often dairy cattle (marbles better, sells for cheaper). The difference in a RibEye will be discernible to the eye, however it wont be in other cuts such as tenderloin, Picanha (coulotte), Tri-Tip, etc..
This why you can find "USDA Prime" Picanha at half the price that top Purveyors such as Meat N' Bone sell for. We believe our consumers are OK paying the premium for more tender meat. That is why we pay for beef with G1 certification which, unlike the inspection of the USDA, goes much beyond beef marbling. We also work with smaller producers and programs in both the US and Australia. Smaller programs by default will typically do better at quality control.
All of our beef is held to the highest standards in the industry, and yes it has a premium attached to it. It is not a huge premium, but one we believe our customers value it.
Tender beef is better tasting, easier to digest and just... nicer. There are OTHER factors outside of Marbling and Tenderness that make a difference such as the acidity of the meat... but that is a conversation for another day.
