Yep in the US microbrews are almost on every corner - we have a few brew pubs around here and one specializes in an ever changing list of ales, its actually a little annoying, you find an ale you like and next visit its gone !
When i first discovered FAT tire in Colorado in the mid 90's it had hardly made it out of the state now you can buy it all over the place.
So sorry cant help you out on these particular ones, also my tastes have changed a lot since i got here in '96 (before i came i was a Lager lout) and now drink all sorts of beers, for example i never would have thought of drinking Hefeweizen when i first got here, now its a nice change once in a while.
Also UK beliefs about US beers, and btw vice versa ( all uk beers are not warm ! ) , are not well represented by Coors, Bud etc. its like comparing Courage best and a real ale
enjoy and please drink responsibly
