Wort Boil, Whirlpool, Filling

When the lautering process has been
completed you can begin with the wort
boil.
Temperature setting (4): 100°C
Timer (4): -- (continuous operation mode)
While the wort is heating up, keep the
ƒ
lid (1) on the mash tun (BHG 410000),
opening it only every 3–5 minutes to
stir the wort. Stir enough to make sure
that nothing burns onto the bottom of
the pot. The higher the sugar content
of the wort, the more you will need to
stir it. Burning is bad for the flavour of
the beer!
Once the wort has reached a rolling
ƒ
boil, add the bitter hops. Do this slow-
ly and carefully while stirring the wort
because it can foam up and boil over
at this point.
Normally, you should leave the lid
ƒ
off the mash tun (BHG 410000), after
adding the bitter hops. Continue the
boil for between 60 and 90 minutes,

stirring repeatedly.
5–10 minutes before the end of the
ƒ
boil, stir the aroma hops into the wort.
At the end of the boil, switch off the
ƒ
heater and unplug the mains plug (5).
Once the wort has stopped boiling hard
(the surface is quiet and smooth), you
can perform the whirlpool step:
Place the cleaned (with 70% ethanol)
ƒ
lauter-/fermenting tun (BHG
without the strainer insert (15), under
the closed drain tap (6) of the mash
tun (BHG 410000). Stir the wort vigo-
rously with the large spoon
it swirling. Take the spoon out and put
the lid on the mash tun (fig. 9).
When the liquid stops swirling (after
ƒ
10–15 minutes), open the drain tap
carefully and let the wort flow into the
cleaned lauter-/fermenting tun
040002).
(1) When all the liquid has been transfer-
ƒ
red, cool the wort to the fermentation
temperature (top fermentation: 15–
20°C; bottom fermentation: 10–15°C)
using the sanitised spiral cooler (spray
it with 70% ethanol) by connecting the
cooler to the cold water supply. When
the wort reaches the fermentation
temperature, prepare the yeast accor-
6 - 6,5 l
ding to the supplier's instructions/reci-
7 l
pe, and then add it to the wort. Make
sure you do not use more cooling wa-
7,5 l
ter than necessary during the cooling
6 - 6,5 l process. The draining water should be
warmer than the feeding water almost
6 - 6,5 l
until the end of the cooling process.
Move the spiral cooler in the wort in
6 - 6,5 l
order to improve the heat transfer. You
may also use cold packs to accelerate
the cooling process. Be sure to ensure
absolute cleanliness and sterility!
Close the straining pot with the lid (9).

Ensure that the room in which the fer-
