Steelhead

We did the sampler here and, boy, that was the right decision.
Our favorite by far was the one the 3 seasonal beers they gave us.
Since these are not listed on their website, I'll have to go from memory.
It was a strong ale.  Very nice.  At first I thought I had a bit of an aftertaste from the excessively chocolatey-flavored stout, but I realized that was part of it's complex flavor.  (Just thinking of it makes me wish I wrote down it's name.) 
As I mentioned, the chocolate stout was a bit much.  Great, but we were very lucky to get just this small glass of it.  It was more like hot chocolate in flavor than beer. 
Of their standards, I liked their IPA the best. 
Although I am not really a big guy with blondes (not just the beers), I did like their blonde.
As expected, their Hefeweizen was not to my taste despite it's fun name: Hairy Weasel.

Sweetgrass of Grand Teton Brewing

Sweetgrass is a very smooth and drinkable APA (American Pale Ale).
Good one to have with a meal; not too strong as to interfere with the taste of what you are eating.
For an APA it is not too hoppy, which makes me happy.
