Spent yeast cells = bee food?
I have a friend who's a homebrewer. When he heard that I was looking for Brewer's Yeast to feed my bees, in patty form as a pollen substitute, he said, "Why buy it? I just put it down the drain! I'll set aside a bucket full for you the next time I rack."
Of course I accepted, as the price was right (free)!
My question is, will bees accept "beery" smelling, semi-alcoholic, spent yeast as a pollen substitute, or will they turn their nose up at it? The relative "wetness" of it shouldn't be a factor as I'm mixing it up with sugar to make patties. But, does anyone have first hand experience with feeding bees "trub" and how do they react to it?
Thanks in advance,
