Yes! You simple mix one cup ground coffee to four cups water in a large jar or follow the directions for your cold brew pitcher. I like to use coarse ground coffee so it doesn't leave a sludge at the bottom of my cold brew pitcher. Leave in the refrigerator at least 24 hours and then strain. Enjoy your cold brew concentrate for up to two weeks when stored in the refrigerator. Let's be honest though, mine is gone way before two weeks.
