Brew day is ~8 hours, I would say it's half nannying, there's usually 2 hours where you can full on walk away, but the rest is either active cleaning or you have to press a button or stir a thing every 10 minutes so you are glued to your pot

Bottling is another ~2 hours or so (sanitizing bottles and capping them, cleaning the used fermenter) - you can cut this down to half an hour if you forego bottling, but that's another $1500 in capital costs for kegging equipment

Oh no, your boss values your time very highly. They just want to keep all of that value for themself.
