Was at Flat Branch in Columbia, MO a couple days ago and had an interesting twist.
This beer used a blend of the large, mild Anaheim chile (think chile relleno) and the smaller Seranno pepper that packs more heat than a Jalepeno. Definitely more up front aroma and flavor than the other chile beers I have had that you don't notice the heat until 5 seconds or so after you sip it.
