Interestingly, one of the reasons I decided not to open a brewery is similar to frustrations I've heard about in the west. You can't (or couldn't -- I think these laws are in the process of being changed) build a really small brewery legally. You had to produce at least 600 hl a year. I couldn't self-finance that kind of operation (I might be able to brew that quantity, but there is no way I would have time to sell it). I would have no trouble raising up to $1M but nobody willing to fund that is looking for a modest return. They want to see expansion plans right off the bat. So this means having plans to build a large factory in the next 10 years. I like brewing beer. I don't want to organise a large industrial factory :-)
Probably the same reason I'm still a programmer and not running my own startup...
YMMV, though, as I've only read and discussed the topic and not experienced it myself.
