Decant into a sterilized 30l plastic cask by means of a hopper (refer to
the illustration) or hose. Disinfect the cask and decanting aids
beforehand with sulphurous acid. Do not allow the residues on the
boiler's bottom to flow out with the wort.
Add 7g of dry yeast into the wort and seal with fermenting cask with
the fermenting bung and the sulphurous acid that is poured in above.
Store the container in darkness at 16°C to 20°C. The fermentation
begins after approximately 12 hours. Do not forget: decant 1.5l of
wort into a container or similar receptacle and freeze it (before adding
the yeast).
Thaw out the frozen wort and carefully pour it into the
fermenting cask 1 hour before the decanting [i.e., bottling].
Use a ladle to skim off the foam that is floating on top. Do not
move the cask any more. Decant into the bottles with a hose.
Only fill the bottles up to between 90% and 95% of their
capacity. Allow the bottles to stand at the same temperature
for 1 to 2 days and briefly ventilate them daily (only at a high
overpressure). Then allow the beer to mature at 10°C to 15°C
for another 3 to 4 weeks.
The fermenting duration is 3 to 5 days. The fermentation has been
completed when no fermenting gases escape any longer. The
maturing bottles must have already been prepared during the
fermentation. Sterilize the stirrup bottles in the oven at 130°C and
allow them to cool down in the oven. Boil the rubber seals.
Stir the hot wort vigorously (whirlpool effect) in order to clarify
the wort. Put the cooling spiral (accessory) into the middle of the
boiler immediately after the boiling ends. Connect the spiral to
cold water and begin the cooling. Caution: boiling hot water will
flow out of the spiral at the beginning. Cool down the beer wort
to 20°C. You must work in sterile conditions from now on
because of the risk of infection. Allow the separated cooler sludge
to be deposited on the bottom. Avoid vibrations. Duration of
approximately 25 minutes.
