What point? The moment I lost my sanity.
Seriously if you love making beer and it is what you want to do do it. It is a fun, challenging and satisfying career (well, the latter not so much financially.)
The jobs in the brewing industry that pay the most are going to be on the QC side, think micro biology and chemistry. A head brewer will make an average of $29-50k per year (the latter for lots of experience.)
I should add I opened my own brewery over 8 years ago. While I'm worth more on paper I make a lot less than I did annually at my original career. If you open your own business you better have a solid understanding of business management. That is where most companies, including breweries, fail.
