Why exactly are you looking for beef that is that old? Did you get inspired by watching Faviken or something?
Unless you groupbuy a cattle that a rancher is willing to slaughter and divide up it will be difficult to find what you are asking for. In France it would be easy, here not so much.
I believe that kind of beef usually comes from retired dairy cows. The times I’ve had it I believe the chef bought the whole cow direct from the dairy.
My interest was peaked last year when a friend raved about the meats served at Hawksmoor in London and yes, got reminded in the faviken episode on mind of the chef.
That looks phenomenal. But there doesn’t seem to be an on-line store, so I imagine trying to specially order that particular kind of beef might entail quite a monetary output? Like arranging for them to ship a whole side/quarter of beef? I’d be interested to know more about it.
After having phenomenal old beef at Asador Etxebarri in Northern Spain, I was excited to see old dairy cow on the menu at Otoño in Highland Park (from Mindful Meats in NY). Sadly, it was underwhelming; okay but nothing special or especially flavorful.
I sent them an inquiry and appears they are only retailing from their farm store in upstate / central New York, about 2.5hrs from the city; pickup only.
Waiting to hear back from Meat Hook if they carry any at their Brooklyn butcher.
