WHAT IF THERE IS NO PRESSURE BUILD UP AFTER 1 DAY?
If the pressure does not build up and the yeast is actively
fermenting as seen in the sediment bottle, you likely have a
leaky seal in the rim/lid or VPRV. See the Trouble Shooting
Section, Problem 2 for a solution. Lager yeast can sometimes
take more than 1 day to get active.
WHAT YOU WILL SEE IN THE SEDIMENT BOTTLE
Figure 40 shows what you will sometimes see in the sediment
bottle for Nottingham Ale yeast over the first 4 ½ days for an ale
fermentation. The yeast cells will start to become active after
a few hours and begin to ferment. They will then disperse into
the vessel due to their own CO
2
production and consume the
sugars and other nutrient in the wort/must and multiply. When
the sugars are depleted most yeast will settle in a similar
manner as shown in Figure 40.
On other occasions the Nottingham yeast may grow very well
and be very active and fill a sediment bottle with yeast, as
shown in Figure 40A. In this case you may not get a clear
beer line above the yeast. Don't worry, just carry on as per
these instructions. You'll end up with clear beer in the end.
Each yeast type also behaves differently so the amount of
settling of the yeast and the clarity of the beverage above the
settled yeast will vary. Sometimes the sediment bottle will
look quite milky if the yeast doesn't settle as well as in the
photos. Don't worry, the beverage will still clarify as the process
continues so just carry on as described in these instructions.
WHAT TO EXPECT FROM OTHER YEAST
S-04
S-04 ale yeast ferments very fast and settles very well. See
Figure 40B. We use it in some of our ales and our cider. You
may find that the ales only need one clarification. The cider
should not be clarified at all and S-04 will settle so well that
clear cider remains above the yeast once the cider has been
cold for 12 hours.
US-05
US-05 ale yeast settles moderately as shown in Figure 40C.
T-58
For a 4-5% alcohol ale, T-58 Belgian Ale yeast will ferment out
in 4 days and then sediment as shown in Figure 40D. There will
be a definitive line between the yeast and beer but the beer
above the yeast line will be quite cloudy still with unsettled yeast.
WB-06
The wheat beer yeast we use will settle as shown in Figure 40E.
W34/70 and S-23
Lager yeast like W34/70 and S-23 used in our lagers and
pilsners, will settle quite well after fermentation, as shown in
Figure 40F.
So by Day 6 there will be quite a well defined boundary between
the yeast and the beverage above, before you put the cooling on.

PRESSURE RELIEF SET-POINTS
The brewery has three safety pressure relief systems
1. The VPRV will release at 2.2 – 2.5 bar when fully wound
down, so the brewery will not hold more pressure than this.
2. The lid seal will pop out at 2.5 – 3 bar.
3. There is a pressure relief valve inside the tower by the gas
cylinder that will release at 3 bar.
