If you rouse the yeast vigorously per the instructions, you will
drive off the excess CO2 leaving the beer with the saturation level
of CO2 for the ambient temperature.
Just add the CO2 generated from the PrimeTabs to the saturated level
for your temperature to get the finishing volumes of CO2.
For example, at 70 F the green beer will contain 0.85 volumes, 4
PrimeTabs in a 12 ounce bottle will yield another 1.52 volumes, for
a total 2.37 volumes.
Mini-Kegs
If you have a 5 liter mini-keg system you should use 40-45 PrimeTabs
for the keg. Mini-kegs are primed at a lower rate than bottled beer.
Bottled beer is about 1 ounce per gallon, mini-kegs are about 0.6 ounce
per gallon. A 5 liter mini-keg is 1.32 gallons, hence you need about
0.8 ounces for a mini-keg. Since I think that 1 ounce per gallon is
a little high, I suggest using 3/4 ounce per 5 liter mini-keg. This
means 43 PrimeTabs.
Party Pigs
Party Pigs are 2.25 gallon systems. At 0.6 ounce sugar per gallon you need
77 PrimeTabs for 2.25 gallons. A useful range is therefore about
70-80 PrimeTabs per pig.
Tap-A-Draft
Tap-A-Draft are 6 liter systems. At 0.6 ounce sugar per gallon you need
52 PrimeTabs per 6 liter bottle. A good range is 50-55 PrimeTabs
per bottle.
