I have a layer of sediment at the bottom of the bottles just 2 days after bottling. Is this normal? Should I shake the bottles to put it back into suspension?
It's hard to say what's "normal" in bottling, because most of us just stick them in the closet for 3 weeks...not worry over them.
Step away from your bottles for the next 19 days...Don't stare at them, don't move them, don't obsess over them...They Yeasts don't need your help...they're fine...they know what they need to do.
