There aren’t any waste by-products while creating beer?
Anyway, it sounds like there are ~two~ issues here:
* pollution of the water in some way so that it their sources are marred or impaired in some way
* compensation not paid to villagers that invested in the brewery
My guess is that if /you/ tasted the stuff, you wouldn’t want to drink it either. There’s beer and then there’s swill.
Just Wort. It could be used as livestock feed
There is nothing wrong with Tsingtao
