Sulphur?

[flavaham]

I have a Saison in primary. It has smelled great for the first two days but I woke up today and smell sulphur out of the airlock. Is this normal?
thanks,

could be bacterial contamination or simply biproduct of fermentation if sulfate compounds are present at low levels. Could be indication of autotrophic reaction but I would think that if it has only been a couple days that would not be the case. Hopefully the CO2 purged your H2S out since your post and you have a great brew awaiting.

Some yeasts are also sulfur producers during the ferment--it's more common with lager yeasts, but there are some ale strains that do as well.
