The best way to make cold brew coffee at home Once you try our cotton cold brew coffee filter bag you won’t go back to fiddling around with paper filters, metal cylinder filters, and the like! At Doppelgänger Goods (sister brand of Doppeltree) we stand out above the competition with our premium natural organic cotton cold brew coffee bags. 3 Reasons Why We're Better 1) BETTER MATERIALS We globally source the best natural organic cotton to make our cold brew bags. 2) BETTER CONSTRUCTION Our cold brew bags are hand-made and use a super fine weave (to all you aficionados out there the weave is about 90μ microns) so that only your delicious brew gets filtered out. If you’ve used nylon filter bags before you’re probably familiar with the “sludge” that inevitably ends up in your cup. With our cold brew coffee bag just filter once and you’re done; no need to filter two or three times to get rid of the sludge. Go ahead and wring every last drop of your cold brew out of the filter bag. Our bags won’t tear or fray. 3) EASIER TO USE The last thing you want to do after you’re ready to enjoy your freshly made cold brew coffee or nut milk is to spend minutes trying to pry and loosen a wet cotton drawstring. That’s why we decided to use a nylon drawstring instead, which makes untying the bag a fast and simple process. We also made sure cleaning the bag is easy too. Just turn the cold brew coffee bag inside out, dump the grounds directly into the trash or compost bin, and then rinse it out under the faucet. Let it dry and you’re ready to go with another batch the next day. This product is currently available to customers in the United States and Canada.
