Projection Question(s)!

Greetings all,

We are in the process of planning a 15bbl 100-seat brewery & taproom in Southern California. Our current stage is still quite early - somewhere in between rough-draft of business plan completed and a more polished version. We are trying to clean up our projections.

As far as the taproom goes, I have been using the apparently consistently applied Xbbls / seat / year model. I have read that the range is 3-10 bbls/seat/year. For my projections, I think I have plugged in the medium-low number of 5bbls/seat/year. What is much more difficult is estimating sales to bars / restaurants etc. I know that this number will depend heavily on the specifics of our area (southern Ventura County), but is there a good way to get this estimate? Are there any tools available?

Anyhow, any feedback is appreciated. This is the first time I have posted on here about our plans, so anything helps!
