Last week after about 5 days my fermentation slowed to about 3 bubbles a minute, was previously going over 70 a minute. So i transfered to my secondary fermenter (a glass carboy). I took a specific gravity measurement at that time, but my question is, is this my Final Gravity measurement? Or do i wait for bottling day to take a last SG reading?
I’m currently seeing small bubbles in the airlock.
You know you’re at FG when you get 2 or 3 identical hydrometer readings, each a day or two apart. Airlock activity can’t be trusted to verify that you’re at FG, or you run the risk of bottle bombs. Make the hydrometer your friend. Good luck!
You should confirm that final gravity has been reached in the primary before racking to a secondary clearing vessel. You can also skip the secondary vessel if not adding fruit, oak, fermentables, etc. The beer will clear nicely in the primary given enough time. Three weeks is my typical primary time for most ales.
Your beer may not have finished fermenting in five days. The bubbles you see in the air lock may just be CO2 coming out of solution or the fermentation trying to finish.
Thanks for the info. I was confused by the contradictory instructions in the Brewers Best kit that suggested
“When fermentation is complete (no bubbles for 48 hours) take a FG reading”
They also recommended “When the fermentation slows (5-7 days), but before it completes, simply transfer the beer into the carboy and allow for fermentation to finish in the secondary.”
So if transferring to secondary is not recommended “if not adding fruit oak or fermentables etc.” Do most people stick with their plastic bucket for entire fermentation or do they switch to the carboy before/after pitching yeast?
I would prefer using the carboy because i can see what is happening inside.
I use Better Bottles (plastic carboys) all the way through. I’ve tried buckets, but never really liked them. Nothing against them, I just always had ones with spigots which skeeve me out as they seem impossible to clean.
I ditched glass years ago due to safety concerns.
Go with what you like and don’t be afraid to leave the beer in one vessel until completion.
I’ve stuck to using buckets, they seem to be the cheapest and easiest to use. I originally bought a conical ferment chamber with a ball valve drain and I was disappointed at how expensive it was, here I am still using buckets over the expensive fancy stuff.
