How would I know if it ferments out properly? Should the foam on the top be thick? Or does it not really matter.Rocker1986 said:Increase of yeast won't change the likelihood of bottle bombs. If you do add extra yeast just open the lid and throw it in there, no need to stir it or anything. Use all of it. However, it may be better to let it go for a bit first and see if it ferments out properly. If it stalls you can throw more yeast at it if needed, but if it doesn't then you can save that yeast for another brew. B)
The guy at Coopers seems to thinking could be okay even though the yeast is lazy.
He said smell and taste it before bottling, if either is bad then toss it but if not then bottle it up.
