Hot Break & Cold Break – What are they?
Hot Break and Cold Break are the terms used to describe the flocculation of proteins (and other matter) during the boil (hot break) and during the cooling of the wort after the boil (cold break) this ‘break’ matter settles out at the bottom of the boiler and forms a part of the ‘trub’ which is normally filtered out by a hop bed when transferring from the boiler.
