The paper is focused on optimization of the coarse break separation. The coarse break hinders wort clarification, increases the amount of break – rich sediment and thereby increases the losses, causes final filtration of beer very difficult. The amount of coarse break is about 6 000 – 8 000 mg/l, after its separation should decrease under 100 mg/l. In the past the coarse break used to be separated in a coolship or settling tank, but nowadays are frequently used whirlpool yet reliably tested.
