I don't know about somewhere that will make it specifically for you.....but with already having a liquor license you might as well invest in the equipment and a brewmaster. I know where I live there are plenty of microbreweries in the area whose beer is carried in stores, but it still has to go through the beer distributors. From what it sounds like though is you want a microbrewery for your bar, but don't want the microbrewery.... Only way to really achieve that (I would think correct me if I'm wrong) would be to partner up with one. What stinks about that is, and it may be different with your laws, but where I live you would still have to go through the distributor. The only way around that would be if you combined the business, and once again this may be only where I live, but make sure to keep the original name for both the bar and brewery because you can be forced to start your business's credit history over by simple adding another name to the business.
