Perco uses an entirely new method that is not found in any other coffee product. Rather than taking the time to cool down hot coffee or make cold brew overnight, Perco combines hot coffee grounds and cold water to produce cold coffee straight from the filter. The small pot is filled with ground coffee beans and placed on the stovetop to warm for a few minutes. It can then be moved to the rim of a glass so that the user can slowly pour cold water over the grounds. Using the grounds as the heat source instead of boiling water, the coffee brews in the same way but still leaves the filter cool. The minimal and compact form can seamlessly move from stove to cup and streamlines the process of morning iced coffee.
