sorry i had an emergency plumbing issue and must have posted before i read what i wrote the 5 gal with the fancy liquid yeast is doing nothing the safale-04 is bubling away and still the liquid hasn't produced a single bubble it has been in the fermentor for 4 days now any my only thaut is that it may have froze it was in my truck for a couple of hours after i got back from the lhbs

Is the fermenter perfectly sealed? Bubbles are a pretty poor indication of fermentation, since a bad seal will destroy any chance of having bubbles come out your airlock.

If you really want to get technical about the experiment, pull a gravity samples every few days from each and see how it's fermenting. Then, once everything's bottled, do a blind taste test.

But I doubt your yeast is bad. Yeast can survive conditions that would likely kill me or you.

i did finaly see one bubble i think my root cellar is a little chilly i will wait till tomorrow to pull a gravity reading and do so every couple of days i usually dont pull readings untill every thing mellows out for fear of contamination and less beer for drinkin
