Welcome aboard Ed. Sounds like you are having a lot of fun up there. Hope you are staying dry. I have never seen a mason pit in person but would sure like to see one in action some day.
I can give you a basic run down on the bottling process. First you need to find a local co-packer. Basically you meet and discuss options and operations (i.e. sizes of batches they contract, labeling, etc.) You take in a test batch which is a small amount. Only a few ounces. They run tests on it for PH levels and other tests to see how it may fair on the shelf. Than you submit the recipe and they make a test batch for your approval or make neccessary corrections. From there you get camera ready art made up for the logo and have a test label printed. That get's turned into the co-packer for approval making sure it meets all the FDA requirements. The co-packer should be able to refer you to a printer'grapics design they work with regularly and know what needs to be done to meet requirements. Once that is accomplished, you pick the bottle type you like and you're in business. Some will market for you, others won't. Some may help set up demos at food stores. Yes, that means you get to be the lil ol lady in the store giving samples. I will be there myself. Thimk I will leave off the red and white checker, frilly apron though.
Do your homework and check out different co-packers. Even one's down the road a bit. Once set up, you won't have to make trips anymore, just send a check. Also see if they handle distribution. It should be a small fee to do so, and saves alot of time. They already know thier buyers and the market.
Weekend homework. Go knocking on doors at supermarkets, local specialty food stores, anyone that sells kitchen and bbq supply, even costco and sam's club carries local product. I have seen a hawaii only bbq sauce from a local joint for sale at costco. Talk to the managers and set up a demo. Make chicken or pulled pork ahead of time and just show up with an electric skillet and your product to serve.
Holy smokes I am getting long winded here. Anyway that's the jist of it. I hope you do well.
