When starting a business a lot of people will give you a lot of reasons why it won't work. When it does work it can be very satisfying. There's nothing like it. Just do a lot of research and planning before you decide to commit yourself to the business.
Two words: Due diligence.
This is great advice. There are a million reasons not to start your own business, and you should really be aware of those reasons.
My mom's "retirement" plan was to buy a campground. Pretty much all of her friends told her she was crazy to sell her house, move to another state, and own a business. It's been a lot of work for her, but in a little over two years she's making about 10x as much money each year as she did at her last job. It took her about 5 years to find one that grossed enough and was cheap enough for her to afford, and in those 5 years she did a lot of research.
Another thing to think of is alternative revenue streams. I know a guy who wanted to start a coffee shop. He found an investor to help with the down payment, and they bought an old warehouse for about $1m. They gutted it and turned it into 5 different retail storefronts, and artist studios. His coffee shop is one of those retail stores, and they rent the rest of the building. Even at half capacity, the renters more than pay the mortgage. At full capacity they make a lot more than the coffee shop ever could.
If you need to lease/buy a brewery, why not buy a big building and earn some rent, if you can get the capital together for the down-payment?
