It can be done but it is a lot of work to get everything in order. Even then, selling only a few kegs to a few pubs would likely not be worth it IMO unless you make a beer that is in high demand. You essentially need to have one or two flagships that make up the majority of your sales and then have some small batch stuff that follows suit with the quality level. If you do what one of the local's does (brews on a 1bbl setup that he slides into his driveway) and sells to a few local pubs you will have a hard time unless you have really good product. This local I speak of, IMO, does not make quality beer and in fact it tastes like it's cut with water to me which is specifically why I decided not to carry his beer in my taproom. That and he doesn't seem to understand beer or the local market as much as I think he should.
