While I know this survey is biased, it’s people who watch Brulosophy content and answer surveys, but my own experience backs this up: https://brulosophy.com/2024/05/27/2024-general-homebrewer-survey-results/
My personal experience mirrors that as well. Everyone in my homebrew group is that. Everyone in surrounding groups (as seen in pictures of state-wide gatherings) is that. 95% of the people I see in homebrew shops are that.
Why?
You aren’t wrong. For me, I wanted cheap imperial stout all year long. It’s hard to find, and it’s always expensive, and happens to be my favorite. And I fit your demographic.
Maybe as a whole, DIY is a “middle class white” thing. Crafting, home improvement, gardening, etc. and beer is just a male-centric version of that.
