Here is a little list of things you need to accomplish if you feel like you wanna open up a nanobrewery of your own. I guess it is relevant for a full scale brewery too. I actually made this list for JC of Trillium Brewing, who will probably be going down the smaller scale road like us.
Local /County Government:
Planing Department: this is where you gotta go to make sure you can actually open up a brewery at your desired location. If not you'll have to appeal to the government and get Conditional Use Permit.
Department of Environmental Health: If you are going to have a tasting room you'll have to deal with your local DEH. Make sure you get someone that knows what they are talking about.
State Board of Equalization: You need to have a seller's permit which is a local/county run deal.
Business License: A license to actually do business in your city.
Building Permit: If you are doing any serious construction this will be needed. Sometimes even for smaller jobs too.
Department of Health: if you are opening up a wholesale food processing facility, which is the category a microbrewery falls into, they will need to approve you facility.
Alcoholic Beverage Control Board: This is the basic license application. We have a type-23 microbrewery license. We have all the same rights as a type-01 license holder except the fee is considerably less.
Paperwork you'll have to file: Personal Affidavit, Additional Affidavits, Personnel Questionnaire, Corporate Questionnaire (if you are an LLC/ Corp), Diagram of Brewing Facility, Zoning Paperwork, Consideration Point (i.e. schools, churches, etc.), Residence (i.e. if you are close to non-commercial buildings), Signature Sheet (for LLC/Corp), and Tied-House Restriction Paperwork. All in all about 22 pages of paperwork.
Excise Tax Division of BOE: An excise tax permit is required as well. They require a bond as collateral.
LLC or Corporate Articles of Incorporation: Done through a lawyer and usually a yearly fee associated with this as well ($800-1000 per year)
IRS Employee ID Number: This is just to keep track of your business taxes. Easy to obtain, just a few pages of paperwork. I think it can be done through their website.
Alcohol & Tobacco Tax and Trade Bureau: They require a collateral bond for taxes and you need to pay taxes on every barrel of beer you produce and sell. Minimum of $1,000 bond is needed as collateral.
Paperwork you'll have to file: Brewer's Notice, Brewer's Bond, Personnel Questionnaire, Power of Attorney (for LLC/Corp.), Pay.Gov User Agreement, Environmental Information, Quarterly Excise Tax Payment Procedures Checklist, Supplimental Water Quality Information, Signing Authority (for LLC/Corp.), Legal Description of the Brewery, Description of Security, and a Diagram of the Facility.
I hope this is insightful for anyone looking to get in the brewing game.
