Recently got a used fridge to ressurect my first kegerator hardware setup. All main taps are in thengarage, inside will have Sparkling water and my wife wants cold press coffee. So got a nitro setup and I need to swap out one of the faucets. 3rd tap will have cocktails or whatever. I don't drink coffee. I know very little about it. From what I was reading you corse grind beans, put in a strainer bag and soak until desired strength. Filter into keg, serve. Is that it? Doing 1 gallon batches into a cannonball keg. It's a beer gas mix through a stout faucet to degass it.
