Couple more pics of the brewery itself, all done up and a few upgrades. Some tables and chairs coming later this week, or next. I am a little worried about keeping up with production, gone through about 4bbls last month.
Here is the main taproom today:

well, that pic didn't have the pong table. What brewery is complete without beer pong?

And the dart room
Here is where I store kegs, so when I kick one I can replace it cold.
all and all, its been great! I have managed to pay my bills, and get a few upgrades along the way. Its allot of fun owning a brewery and chatting about beer all day.
