I'd like to brew coffee for a class I am teaching. I'll have about 20 students, and want to showcase local roasters and single origin coffee from different countries. What is the best, cheapest way to brew specialty filter coffee at scale?
I have a v60, chemex, aero press, etc., but don't think I'll be able to get the volume I need for 20 people. I can maybe buy a cheap coffee maker at a thrift shop, but I doubt I'll be able to have the control I would like in terms of water temperature and ratio. Not filtered, but I have thought about a French press, but even that only has so much output.
Tried posting in r/coffee yesterday but it is still waiting for approval. Sorry if this isn't exactly appropriate for this sub.
Thanks in advance!
