With our system, I "could" brew and sell 2bbls a week. However, This is still really a hobby for my wife and I. It's nice that it's a hobby that pays for itself, and there's money to invest in better/cooler equipment and such. We sell about 2bbls a month. And recently turned down a new account, as we want a life as well. Our day jobs provide much more $$$ than brewing on a 1bbl system could provide.
micsager, so since you have contracts I am assuming that you are fully licensed commercial nano? In going with this thread, do you have any information to share surrounding commercial and home owners insurance? If you are doing a 1bbl and have your full time job like me, I am also assuming that you are not leasing a building them.
We are fully licensed by the state and feds. We do this in a separate building on our residential property. And "accounts" should not be confused with "contracts." I have no written agreement with the two places that buy our beer. They call when they need a keg, and I bring it to them.
We have homeowners insurance to cover our house, and garage. And a separate commercial policy for the brewery building, equipment, etc..... And also product liability insurance, should our beer make someone sick. It's really cheap, and gives us peace of mind.
