When I make cold brew I tend to use a filter bag, makes cleanup a lot easier. While I would love to go on a tangent about sourcing local specialty coffee & grinding just to your dose to keep your beans fresh, those don’t matter quite as much for cold brew as they do for espresso & pour over. What really matters is if you enjoy the end result, so if there’s anything that you don’t particularly enjoy about your cold brew you can determine the root cause & adjust accordingly.
