Whoa, not pure BS and hyperbole....
$500k for a brewery is not far fetched, maybe a bit high. Yes, you can do it for around $250-$300k. But, you better want to work, and be willing to throw down buckets of elbow grease. And you really need to be lucky to find a location that suits a brewery decently well. And there are a lot of people that dont want to/have the skills to do that work. $500k is a pretty normal budget number to start a 7-10bbl brewery. If you want to go 3bbl, $250-$300k sounds about right, or maybe even a little less than that. But you will be doing a lot of work, hoping nothing goes wrong, making decisions on stuff because of the money, not because of what you actually want or need, and your butt will probably be puckered until you get your beer sales going.
And, just my personal opinion maybe, but if you want to be very successful in this, you cannot operate on a 3bbl for an extended period of time. ANY success, and you will be brewing 5-6 times per week, or more, just to try to keep up. 3bbl can feed restaurant/pub beer sales, but is not large enough to keep up with inside and outside demand. But, this is getting off topic from what OP was after.
Also, insurance being $45,000 a year is wayyyy too much. I got a quote from Nationwide for Gen liab, Liquor liab, Business auto, Commercial property, and Workman's comp. It was like $450 per month.
Dont mean to be negative, just mean to be realistic.
