Man, that reminds me of the kitchen in my last house! I use to do the same 3 tier thing as well, except I would collect directly onto the stove to heat my wort up before carrying it outside for the big burner!
My girlfriend wouldn’t care if I was brewing in the living room as long as I’m making beer. We actually have 6 carboys of mead in secondary in our bedroom. Its romantic.
My wife is OK with it… She’s tolerated my hobbies for the last 20 years! 'Course I make sure it’s all cleaned up when I’m done… She appreciates that. [emoji6]
My brew days are limited to when I have a day off while my wife is working. She can’t stand the smell, with the exception of bottling days for my hoppy beers - that is the rare time when I get a “what smells so good in here?”.
As a matter of fact, I’m working 3rd shift right now and my wife will be at work when I get home. I’m already trying to figure out how much sleep I can get by with to see if I can squeeze in a brewday.
