During my jobs in Spain I have made the
experience that the iberico bellota ham (acorn fed) is not from this world.
It has a flavor than no other ham and mouth watering that, if you once had the first piece you run into a rush and can't stop eating.
Coming now to the price: If you can affort it to pay 4000$ then it might be worth it. But coming to the point you eat a ham then it's a ham with another taste and I cannot find the 3800$ difference to any farmer's ham who put love and patience in his ham made in his cellar.
Grass fed Iberico is cheaper and still the meat is top of the notch taste. May it be a Loin, A Belly or just a shoulder piece.
The Iberico Pork is a Breed that stands out in taste and marbling and I would pay the 13$ per Lb as soon I have a chance to get hold on. (Suits my wallet also more)
Put a Berkshire, Duroc and Iberico on the table, let Grandma do her Sunday roast and you might be disappointed when you taste the Berkshire as an Iberico..
Fact:
The Ibericos grow up in a Landscape that is unique and so will be the Pig itself. Putting all these facts together and you want to be a part of the top
class ham society, well then you need to pay the price before sold out.
But if you accept a slight difference in the taste support your local farmer as long he treats his pigs with love and respect and feeds them naturally.
Just my humble opinion
