I've had two chile beers.
Eske's brewpub in Taos (New Mexico) was my first taste of it, and while it was novel for a sampler, I had no great desire to keep drinking it.
But then I had a good one. Rio Grande brewers (which is now part of Sierra Blanca brewery in Moriarty (New Mexico)) makes one that you can drink all day. The key is subtlety: the chile doesn't hit you over the head. You might not even notice it or be able to identify it, at first. But after a while, you get a slight burn at the back of your throat. It's good. I live in Albuquerque (about half an hour's drive away) and it's just a matter of time before I go back there and buy another case of the stuff.
