That's awesome. I recently discovered that Meridian Hive's brewery building is within walking distance from the building I work in and I've been meaning to check it out.
Next time I head out to Jester King, I'll have to check them out!
Circle Brewing
Austin Beerworks
Adelbert's
Black Star Co-op
These are all in fairly close proximity to each other and should be away from most of the SXSW crowd.
Austin Beerworks is one of my favorite locals and their Heavy Machinery IPA series hasn't let me down yet.
