Cascading hops reservoirs for recirculating brewing system

This invention describes a system for adding hops or other flavorings to beer during brewing in stages. It uses a series of containers, where brewing liquid flows into the first one, passes through the hops, and then drains out. If the liquid level rises too high, it overflows into the next container, allowing for new hops to be introduced while the liquid continues to recirculate through the previous stages. The claims specifically detail a first container with a drain and an overflow, and suggest a second container whose drain combines with the first.
