Despite being the most expensive manual model in our ratings, this KitchenAid cold-brew coffee maker has just over half the capacity of some of the other top-rated models. In addition, our testers found its glass carafe noticeably heavy. Nevertheless, our performance tests found it to be efficient, even receiving a Very Good rating for cleaning ease. Depending on how concentrated you like your coffee, it takes 12 to 24 hours to brew.
