Specific Gravity Measurement - Whirlpool Vessi Use And Care Manual

USING YOUR VESSI™ FERMENTOR
& DISPENSER
SPECIFIC GRAVITY
MEASUREMENT
IMPORTANT: Be sure to complete
sediment removal steps before taking
a specific gravity sample from the draft
port� This will ensure that no heavy
sediment is pulled through the draft port�
Check and note the CO
output pressure on the CO
regulator�
Check that the 3-way valve knob
1
is in the Off position�
Using the pull ring on the APRV,
lower the vessel pressure to
5 psi less than the CO
output pressure�
Turn the 3-way valve knob to
LIQUID INJECTION� Wait 3-4
seconds until you hear gas bubbling
2
into the vessel� Turn 3-way valve
knob to OFF� This ensures the draft
line is clear of any sediment that
may block the draft line�
HELPFUL HINT: Steps 1 and 2 can
also be used to stir your beverage
throughout the fermentation process�

to purge the draft line of any solids
and discard�
Pour a sample from the faucet into
your specific gravity measuring
container� Vigorously shake

this sample to release as much
carbonation as possible� Insert
a hydrometer (not included) and
record the measurement�
Repeat sediment removal and
specific gravity measurements until
5
no more solids are being removed
and you get the same specific
gravity measurement for 3 days�
