muddydisco said:To stop it, once it had reached the FG I wanted I placed the Fv in a cold enviroment Ie my spare fridge, added 4 campden tablets and 1/2 teaspoon per gallon of Potassium sorbate. This should be printed on your tub's. After 2 days I racked this into another Fv Leaving the yeast behind. Allowed any more yeast to fall out of suspension, then racked into my keg and force carbonated, as it wont carbonate on it's own.
Silly question maybe but did you crush the campden tablets or just leave them whole?
