As someone who is in the process of opening a brewery, it's profitable but not as profitable as you may think. A production brewery with a tap house has to produce an insane amount of beer to be profitable and consider nationwide distribution. I see both sides of the coin, but I know what the economics are as far as production and expenses are. Most brewers and brewery owners aren't loaded. I am happy to have the bills paid and have a little extra at the end of the day and that's how it is for many of us.
I'm not talking about most breweries though. I'm talking about breweries that "aren't huge" if you have hundreds upon hundreds even thousands of people waiting days in line for one read single, 1 bottle of beer, than you are huge. Especially when you're selling beers at $15-20 dollars a bottle from the brewery.
I get the idea of product and demand but when demand is as High as it is for some of these breweries they can easily afford and profit by upping the supply end somewhat. Just seems like a win win for everyone included. More beer made equals more $$ more beer equals more happy customers and not out of towners getting let down waiting in snow for nothing.
