Bought one of those fancy cold brew towers at a kitchen store in Portland about a year ago. I figured I would save money and stop buying the bottles at the store. Turns out you need coarse grounds, 12 to 18 hours, and a whole lot of fridge space I did not have. The filter clogged on the 3rd batch and cleaning it took forever. Has anyone found a cheap setup that actually works, or should I just go back to overnight fridge steeping in a mason jar?
