**Does your wine smell like a burned match or like rotten eggs?**

Hmm, now that you mention it, it is not like the sulpher smell from a
typical lager beer fermentaion, maybe it is a bit, "rotton egg".

Anyway, I'm sure is came from the deacidifier product I added. When I
added it, it foamed like a volcano!
So what is it about that particular deacidifier that causes this smell?
