[Sticky] Federal Brewery Licensing and Laws: The United States TTB (Alcohol and Tobacco Tax and Trade Bureau)
If you want to start a brewery, winery, cidery, or distillery one of the first agencies you'll be dealing with is the fine folks over at the Alcohol and Tobacco Tax and Trade Bureau (or TTB for short). Many people may think my 'fine folks' remark was a bit 'tongue-in-cheek', but with all the department is responsible for they do an excellent job communicating with breweries-in-planning, entrepreneurs, and people looking to start a commercial brewing operation.
Unfortunately, the TTB isn't without its share of flaws. Like many government agencies, they're understaffed and overworked. The wait times to obtain approval for your brewery border on ludicrous (the adjective...not the rapper). To the TTB's credit, they post their average wait times on their website so people aren't blindsided by the long wait time. As of the start of the New Year (2017), the image below is the average processing times by license type.
