It is too soon to even begin to worry....after 72 hours
is when you take a gravity reading and see what's going on. It's quite common for yeast to take 2-3 days to get going, it's called lag time.
, and by visible signs we don't necessarily mean a bubbling airlock. it means gravity reading
It IS a sticky at the top of the beginners forum for a reason, afterall.
"Activity is irrevelent." Just gravity points on a hydrometer.
Airlock bubbling (or lack) and fermentation are not the same thing
. You have to separate that from your mindset. Airlock bubbling can be a sign
of fermentation, but not a good one, because the airlock will often blip or not blip for various other reasons
...so it is a tenuous connection at best.
