Berkshire and Kurobuta Pork
One breed, two names, and the temperature rule most people are still getting wrong.
Berkshire is an English heritage pig breed; kurobuta is the Japanese trade name for the same animal. The meat is darker, firmer and better marbled than commodity pork, and it stays juicy at the 145°F the USDA recommends for whole cuts.
In one line
Heritage pork that is actually worth cooking to medium instead of to safety.
Buy it if
You have written off pork chops as dry and want to find out why that isn't the pig's fault.
Berkshire is an old English breed — black, with white points on the feet, face and tail — that Japan imported, kept and renamed. Kurobuta simply means "black hog". Two names, one pig.
Why it eats better
Berkshire meat runs darker, at a higher muscle pH, with more fat inside the muscle. Higher pH means the meat holds onto water during cooking. That is the whole reason a Berkshire chop survives a few extra degrees where a commodity chop turns to sawdust.
The temperature people are still getting wrong
In 2011 the USDA lowered its recommendation for whole cuts of pork to 145°F with a three-minute rest. That is a pink center, and it is correct. Ground pork remains 160°F.
A generation of cooks learned 160°F and up, which is why so many people believe they dislike pork chops. They dislike overcooked pork chops.
Buying it
Kurobuta has no legal definition in the United States, so it is worth asking what percentage Berkshire the animal was, and whether it was raised indoors or on pasture. Breed and husbandry are separate claims and both are worth knowing.
At a glance
| Breed | Berkshire — English, black with white points on feet, face and tail |
|---|---|
| Kurobuta | Japanese for 'black hog'; a trade name for Berkshire pork, with no legal US definition |
| The meat | Darker, higher pH, noticeably more intramuscular fat |
| Cook it | 145°F and a three-minute rest for whole cuts — pink is correct |
| Ground pork | Still 160°F |
| Best cuts | Chops, belly, shoulder, and sausage made from the trim |

Myths
What people get wrong
Kurobuta pork comes from Japan.
In the US the word is a trade name for Berkshire or high-percentage Berkshire pork, and it is mostly raised here. It carries no legal definition, so the honest question is what percentage Berkshire the animal was.
Pork has to be cooked to 160°F.
The USDA lowered its recommendation for whole cuts of pork to 145°F with a three-minute rest in 2011. That leaves the center pink, and it is the single biggest improvement most people can make to a pork chop. Ground pork is still 160°F.
Heritage breed means pasture-raised.
Two separate claims. A heritage breed can be raised indoors, and a commodity breed can be raised on pasture. Look for both statements, not one standing in for the other.

Berkshire and Kurobuta Pork vs Ibérico
Both are heritage pigs with real intramuscular fat, but Ibérico bellota is acorn-finished and its fat is high in oleic acid — softer and lower-melting. Berkshire is the better everyday chop; Ibérico is the special-occasion cut, and priced like it.
| Berkshire and Kurobuta Pork | Ibérico | |
|---|---|---|
| Origin | England, now raised in the US | Spain and Portugal |
| Finish | Grain | Acorns, for bellota |
| Fat | Firm, white | Soft, oleic, low-melting |
| Best cuts | Chops, belly, shoulder | Secreto, pluma, presa, solomillo |
| Price | Mid to premium | Premium to luxury |
How Crowd Cow sources it
We don't run a dedicated Berkshire program at the moment — kurobuta turns up occasionally, currently as a fully cooked pulled pork. Our standing heritage pork comes from Home Place Pastures in Mississippi, Pederson's Natural Farms in Wisconsin and Mangalitsa Estates in Iowa, with Ibérico from Fermín in Spain.
Questions
Common questions
Is kurobuta the same thing as Berkshire?
In practice, yes — it is the Japanese trade name for the breed. Because it has no legal definition in the US, some products labeled kurobuta are high-percentage Berkshire crosses rather than purebred.
Why is the meat darker?
Higher muscle pH and more myoglobin. The practical effect is that it holds water better during cooking, which is why a Berkshire chop is more forgiving than a commodity one.
How do I cook a thick chop?
Sear it, then finish gently — or reverse the order. Pull at 140°F and rest three minutes; it will carry to 145°F and stay pink. A brine helps a lean loin chop and is unnecessary on a fatty rib chop.
