Does anyone know if 'brewers yeast' actually comes from brewing?
I ask because a there are a lot of dog biscuit recipes that call for 'brewers yeast', but I know dogs and hops is a no-no!
So I was wondering if it really comes from brewing leftovers or not... and I'd assume that home brew yeast (not being re-used) is not a very good bet because of the hops (though I suppose a cider would leave a nice cake of dog-safe yeast).
