Hi, Ken. I do not have any experience with the brews you listed. But, it occurs to me that the good and the bad of microbreweries can be inconsistency. As a homebrewer, I know there are all sorts of variables that can affect the taste of your beer. I love microbreweries because they do experiment a lot more than the big commercial breweries and work to improve their recipes and their brews. Sometimes, that causes a little variation from season to season or batch to batch. I strongly prefer homebrew but there are a lot of very good microbrews out there. And I am willing to put up with a little inconsistency to drink good beer.

Well Pam, I can testify to the Nimbus Pale, this beer can only be called pedestrian at best, which goes for the rest of Nimbus' bottling line. Only the Oatmeal Stout I can put down. Haven't been to the brewery yet. But never fear, Nimbus isn't the only AZ brew that taste like spit.
Cave Creek Chili Beer- I think this is a lager, with a chili pepper in the bottle. More of a novelty.
Sonoran- they've stopped bottling. Thank yer lucky stars
Electric Dave's-
Also not in Az-
Steamworks- has anyone else thought this brewery leans a little towards the lame?
That's all I can think up now, any other bland ones y'all have encountered?
