First time making a witbier, and adding coriander and orange peel to a beer.
It is also the first time smelling rotten eggs from airlock ?
Was the yeast healthy, good pitch rate? That smell is usually associated with yeast.
One packet (11g) of Nottingham yeast was pitched into 4.75 gallons of wort, both @ 62 degrees.
Date on yeast was 6/2021 and vacuum sealed. Been 6 days since yeast was first pitched, bubbling has
stopped/slowed down and yeast cake is noticed on bottom of fermenter. I often smell bubbling airlock when active,
and this time it smelled like hard boiled eggs shelled ? sulfur ? not sure.
The yeast was pitched cooler than normal, and wasn't aerated as aggressive as usual. These are the only variables I can
think of, other than the additions of coriander and orange peel.
