A wort copper (also Sudpfanne , Braupfanne , brew kettle or Sudkessel called) is a technical system, for example, in breweries for beer brewing is needed.
history
The wort kettle is used by the brewer to boil the wort obtained during mashing and lautering for the purpose of sterilization , protein precipitation , hop solution, expulsion of aroma-intensive substances and to set the desired concentration of the original wort .
The wort kettle is equipped for strong heating and a basic distinction is made according to the type of heating. There are pans with direct heating, which is the oldest form of pan heating; pans with direct gas or heating oil are still in use today. The most common type of heating, however, is charging the pan with heating steam. A distinction is made here between heating by means of steam supply in welded-on steam pockets or tubes on the underside of the pan. However, installed internal cooking systems and so-called external cookers, which follow the principle of the plate heat exchanger , work more efficiently .
Smaller wort kettles are sometimes also operated by means of electrical heating rods or heated with hot water.
Modern wort kettles are made of stainless steel and are heavily insulated and often have a copper hood in order to correspond to the traditional construction.
The volume of the pan depends on the desired amount of wort and so there are systems from 10 liters, as used by hobby brewers, up to a capacity of over 1000 hectoliters in pans from large breweries.
Phrase
The idiom The dog goes crazy in the pan is derived from Till Eulenspiegel's prank, according to which he threw a brewmaster's dog "Hopf" into the brewing pan . It is considered an exclamation of great amazement, that something is incredible.
