Real Ale for sure over in Blanco - on the Dripping Springs side. It's a great tour and fascinating given their growth in the past 2 years. I would make sure to to it. Not clear on their hours early in the week.
JK is a nice place, but just overcrowded. I am allergic to hipsters.
In town, there are quite a few, but I would strongly recommend ABGB, and would be happy to be your host there. Maybe could swing a tour, but a brewery is a brewery - usually. They are just south of downtown off Lamar and Oltorf. Another pizza place and sandwiches but the best pils and helles in town (IMHO). Closed on Monday.
Pinthouse Pizza has a solid selection of beers - and a large line up - Pizza is decent. North side of town. Would be a nice day trip up, and work towards the south to some of the breweries.
Uncle Billys has a new brewery system and brewers. Those guys left to start ABGB, but understand the beer is pretty good these days. Don't count on great BBQ there tho.
South of 71/Ben White there is South Austin Brewing <not recommended>, (512) <recommended>, Independence <recommended> and a NXNW location is now South. A little further up 35, there is Whip Inn (Kamala Brewing) which can be hit and miss, but fun. Meridian Hive further north - if you like Mead... and I know the brewers there and maybe could get a private tour setup. It's lots of tanks... but the mead is sessionable and pretty tasty.
Really hard to not hit a brewery with a good throwing arm. ABGB is my favorite... head brewer has several GABF medals and a real character.
