Review on ☕ Rumble Jar 32oz Mason Jar Cold Brew Coffee Maker - Next-Gen with 200 Micron Filter - Perfect for Coarse Grounds & Stronger Coffee - Includes Cotton Filter Sock (32oz Filter-only w/ Orangey-Red cap) by Mandy Martin

Rumble Jar has pushed our daily coffee routine to the limit! So easy to use and clean (I hand wash as it only takes a few seconds). Love that he uses a mason jar. I use mason jar reusable plastic lids so I don't have to worry about the metal lids that come with mason jars rusting. I've used finer ground coffee and it really wasn't a problem. There is a small amount of sludge in the glass after brewing, but I really like it! If you measure your coffee grounds with a scale, 60-66 grams will work for us. I also carefully reheat my cold drink in the microwave as I love hot coffee more than cold coffee!
