Fermenting mash stinks like rotten eggs

[RobJ]

I've done an all grain mash with 60 malt and 40 smoked malt, added 6g brewing yeast and 3 days it it really stinks like rotten eggs n sulphur, any ideas what I've done or if it'll be ok, be grateful for any help, thanks

Some yeasts are known for creating a rotten egg smell during fermentation -- I'm no expert, but Koelsch yeast springs to mind as one example.

These aromas generally dissipate over time from my understanding.

A lot of different yeasts give off a strong sulfur aroma during fermentation. I wouldn't worry about it.
