Most commonly, home brewing beer is thought of as a production for personal consumption activity. However, this may not necessarily be the case always. Even if you started as a hobby, once you know your commercial value, you can go into business. Some people would even patronize you knowing that the production is personally looked over by the owner and not by a multitude of layers of administration staff.
It is not enough, however, to know how appreciated your homebrew recipes are. You should also first look into the economics of commercially brewing your beer. First, will you be able to get beer making supplies at a relatively low cost to be able to price your product competitively? When you brew beer for your personal consumption, you don't normally mind the costs too much because in the end you would want to satisfy yourself with what you are drinking. Like the food connoisseurs, they don't mind the cost of what they're eating as long as their palates are happy. This should no longer be the case if you make a commercial home brewery.
Costs must be kept low. Obviously, you would want to open a home brewery to get some profits. If you are just selling to make other people appreciate your discovered beer recipe, save yourself the bother of going into business. Just hold a party and keep the beer flowing.
When you have calculated your possible cash flows, next to ask should be, would you be able to maintain your excellent brew if costs are lowered? Possible patrons might stop drinking your product if you sacrifice its taste to pull down production costs. If you do so, the whole point of selling your brew because of the demand for it would be lost. It is good to scout for other suppliers other than your trusty just-around-the-corner home brew shop. Other suppliers might be able to offer you better costs than the one you originally go to. Sometimes, it might be more economic for you to get supplies from far areas than be at the mercy of suppliers near you.
There are other things you would need to consider like hiring other people to be able to produce more, registering your business, and other processes necessary. You have to get a patent so that in case another person discovers your outstanding recipe, he or she will not be able to produce it for market. Also, most often than not, your country would have alcohol duties imposed on commercial distilleries. Once you've got these intricacies down to pat, you are ready to open your home brewery.
