I think Chimayo is in NM north of Santa Fe. It's a small village and the chiles are considered holy as is the local church, the Santuario. Only Chimayos coming from that village may be called genuine.
They are trying to keep the tradition alive, but thje importance of the pods is not the same anymore as it was until - I believe - the late 19th century when they even served as a medium of exchange/money.
They were harvesting about 500 times as much back then as they are today.
