I happen to like coffee. Back in my undergrad days, I had a work-study gig in the Biology department teaching labs, doing lab set ups and the like. In those carefree days, we stored our lunch bags and other human-consumables in the research refrigerators. My last duty of the day was put a stirring plate in the refrigerator with a 2L beaker filled with distilled water and I forget how many grams of freshly ground coffee beans. I covered the beaker with a paraffin sheet and turned it on.
Whoever was first in the lab the next morning had to take the cold-brewed coffee out of the refrigerator and run it through a Buchner funnel to clear the grounds from the coffee. We then had almost 2 L of magnificent cold-brewed coffee to dilute 1:1 with distilled water and heat (yeah, usually on a lab hot-plate).
It’s still the best coffee I’ve ever had, coming on 50 years later.
