how much priming sugar???

[robbieo13]

how much priming sugar should you use for a 3 gal corny keg

 

[justbrewit]

just force carb it, less sediment in the bottom of the keg

but if your stuck on priming it, i'd say no more than 1/5th of a cup, i believe it takes 1/3 or 1/4 of a cup for a full size corny
