It seems to have a classic sulfur smell from SO2. A bit like rotten eggs, but not overly offensive. I usually need to get farily close to the airlock to get a good whiff. Hoping that secondary ferment at cooler basement temperature for month or two will improve.
One other question about campden.
I've been using at 1 tablet per gallon to sterilize cider, then adding yeast 24 hrs later.
I've noticed using this method that several batches seem to have a more sulfur like odor
even several weeks into ferment. Does the SO2 from the campden last this long...
Mcmunro,
I believe I have the same LD Carlson Campden tablets as you.
I've been using 1 tab per gallon to sterilize my cider must.
Did you decide that this ratio was the correct amount?
