Fermentation started about 6 hours after I pitched 2 packs of this yeast. I'm relatively new to brewing but thus far I've been able to smell the airlock of my previous batches and know that it isn't infected. But this is the first one that smells off. It's a lot more pungent than any of my other batches. Kind of funky smelling. I'm wondering if anyone has experience with this strain and can reassure me that this isn't my first infected batch.
