The Balance Brewer is made up of three main parts: A lower chamber, a coffee chamber made with a filter, and a Tim Wendleboe AeroPress filter and a water chamber. Essentially, the brewer works like an hourglass. With the three parts put together, boiling water in the bottom, coffee in the middle, and an empty chamber on top (all airtight), the device then gets flipped, and a valve is turned, allowing the water to drip consistently through the ground coffee in about 4 minutes. The process essentially looks like how you might invert an Aeropress, but on a much larger scale.
