I am not sure there is a norm. Some are fast and some are slow. Even with
similar conditions. Some will fizz a lot and some will go quietly about

you are using or the nutrients in the batch or the amount of glycerin in the
must. Or it may be just happy yeast. You have a real party wine going
there! ;o)
