I had a batch that didnt carb all the way and i knew it wouldnt bc i only used a little under a half cup of dextrose. I took a six pack, opened them, poured in some dextrose (just kinda guessed) and they carbed up nicely. I want to do the rest this way however when i poured in the dextrose on the sixer i did they overflowed quite quickly and it was quite messy and hard. If i chill them down do you think the yeast will cease until i warm them and they wont gush when i pour in the dexrose?
