A plate heat exchanger is used for wort cooling. The cooling process takes place in one or two stages. In a single-stage process, cold brewing water is used as the sole cooling medium. The brewing water can be cooled to approximately 1 °C in a separate chiller operated with glycol, ammonia, or brine. The wort enters the plate heat exchanger at approximately 100 °C. Due to the interaction of the hot wort and cold brewing water in the heat exchanger, the wort temperature decreases to approximately 2–3 °C, while the brewing water temperature rises to approximately 80 °C. The brewing water is then used for the next brew, thus recovering energy for the brewing process. In a two-stage process, the hot wort is first cooled to approximately 20 °C using brewing water and then, in the second stage, cooled to the pitching temperature using glycol, ammonia, or brine. The warm brewing water can also be used for the next brew.
