(2-Pack, Large 12in x 12in) Organic Cotton Cold Brew Coffee Bag - Designed in California - Reusable Coffee Filter with EasyOpen Drawstring Cold Brew Maker for Pitchers, Mason Jars, & Toddy Systems

I use a toddy, I originally had a sock which worked great, just got lazy with the need to rinse it out. I've since returned to paper bags, which I use and throw in the FOGO bin. These were purchased from AmazonAU, see below. The beans I get from a little coffee house out in Berwick, Bermuda Coffee, get them to grind it for Iced Coffee. I know lots of people get the coffee from ALDI. Just find a coffee that you like. I do have some concentrate on hand, if I get lazy and miss a day or two of being organised enough to brew.
