I just wanted to chime in here because we are working on a similar brewery setup. Ours will be very slightly larger, but that is not the point. For us, there is a very strong allure to starting so small that failure is nothing more than a big disappointment. For me, the number reason *not* to open a brewery is because of the huge risk of failure if you drop 100K+ in equipment, location, etc... With the way me and my partner (and also HBHoss, it seems) are starting, there is very little risk of failure and little risk of wild success. Sure, we won't make much money (if any) per batch brewing at our size, the thing you have to remember is, if HBHoss gets tons of business and everyone wants his beer, it probably takes less than $1,000 and a week's worth of work to build out his system and quadruple his batch size. The important thing is that you're growing at the same size as your market, rather than starting at 10 BBL's and waiting 1.5 years for your market to catch up.
The other thing is that its just really cool to say you own a brewery!
This is looking great HBHoss! I'm really enjoying following your progress.
