under the vessel to prevent dripping onto the floor, take the
sediment bottle and bowl to a sink (Figure 45) and dump
the sediment down the drain and rinse the sediment bottle
and stainless bowl both well with water.
5. Then put the bowl back under the tank and take the well
rinsed sediment bottle to the draft tap. Put the bottle under
the tap and push the draft tap flow control lever all the way
down to its fully opened position (see its open position in
Figure 46). Then push the draft tap towards the back of the
brewery to create foam to come out of the tap (this is the
foam mechanism part of the tap). Fill the sediment bottle
with foam by allowing the foam to fall to the middle of the
bottom of the sediment bottle and not roll down the side
(See Figure 46).
Foam consists of bubbles of CO
2
that have a positive
pressure. As we fill the sediment bottle this way, the foam
and its bubbles of CO
2
will displace air in the bottle. The
top surface of the foam will retain the positive pressure and
not take in air and as the bottle is filled, we can displace all
air from the bottle.
Fill the sediment bottle to the very top with foam then close
the draft tap and push the draft tap control lever up to its
fully closed position (see Figure 47).
6. Put the sediment bottle (which is now full of foam) back on
the vessel and close it hand-tight as per normal. The bottle
screws on anti-clockwise looking down. Keep the vessel
valve closed, do not open it, and move onto the next step.
7. Ensure the 3-way valve is closed (X position) and open the
clarification pot. Add 30ml of WilliamsWarn clarification
agent to the 100ml cylinder and then transfer that to the
pot through the tea strainer (see Figure 48). Then screw
the lid back onto the clarification pot tightly.
It is important to strain our clarification agent through
the tea strainer because crystals can form in the clarification
agent over time and these can block the one-way valve
under the pot. If the one-way valve becomes blocked,
it will not close and the beverage will blow-back up the
pressurised line, into the pot and out over the brewery.
All liquids added to the pot should be strained except
for water.
NOTE: The next sequence of forcing clarification agent
into the beverage is required for first time brewers to use,
in order to create an exact and known pressure differential
and then experience the amount of “vigorous bubbling” of
clarification agent that is required to mix the agent well.
There is an alternative method described for in Appendix 9
that experienced brewers may like to try after a few brews,
which focuses on the amount of bubbling heard without
knowing the exact pressure differential created.
8. Lower the vessel pressure (as read on the vessel pressure
gauge on the control panel) to 0.50 below your gas cylinder
low pressure set-point (that you checked in step 2 above in
this Stage) by pushing the button on top of the VPRV. For
first time user who have set the CO
2
cylinder low pressure at
1.25 bar, this will mean releasing the pressure in the vessel
from just under the pressure achieved during fermentation
(e.g. 1.5 bar or under as the cooling of the beverage reduces
the pressure a little bit) to 0.75 bar, as read on the vessel
pressure gauge on the control panel.
