Which is why I was intrigued by the Cold Brew Bottle by Primula ($20). The Kedzie makes up to five servings of delicious, smooth cold brew coffee or tea. Share & print these helpful guides and give them to your favorite coffee lover. The filter on the Primula has a removable bottom, which makes it a lot easier to just empty into the trash, but you'll still find that coarsely ground coffee gets stuck in the nooks and crannies of the filter.
