Small coffee shop in Alba, Italy
I think they really mean cold brew. The time says 5 hours and maybe the machine is a filter thingy after they cold brew the coffee in the fridge.
Maybe, but 5 hours isn’t much time for a true cold brew. I am leaning towards cold drip, where the ice water slowly drips onto the grounds. In the right setup maybe that would take 5 hours.
Looks like you’re right. Does five hours seem anywhere near enough for cold brew, though? I typically aim for around 36 hours.
