What about the yeast hydrating dish though? Should that be rinsed after using Star San?
No
I just hydrated some yeast at 30-35c (I did give the bowl one quick swirl in water first) but the yeast hasn't hydrated like it usually does, looks odd, not 'foamy' like it normally is, and I swear there's a slight 'soapy' smell to it. (See photo) I haven't used it, just got annoyed and pitched some dry instead.
It's kept in the fridge at my end below 8c (don't know about the supplier, online seller) but their yeast has always been OK.
Am I right to suspect the Star San?
As long as u mixed it to instruction / or it wasnt a really old batch(Gone milky colour), then NO, its not the Starsan
I dont rehydrate packet dried yeast, I did a couple of times and it was just a pain in the arse, half the yeast sticks to the container when tipping it in the fermenter blah blah blah, so I dont rehydrate
