>what is used as a protein source in patties for California? Brewtech brand roller dried true brewer's yeast (from beermaking). I'm talking about the mix your own guys (who do it on large scale here). >Nor is all brewers yeast [equal] You're absolutely right! Some here are using yeast from ethanol production. Some find that it works, but I find that the bees don't like it, and that it hardens like concrete! Some also use the commercial sacked formulations (some of which contain soy). Megabee is catching on, which says a lot, since these guys don't waste a penny. Mann Lake, Global, and Norm Carey make custom mixes, which are also widely fed by those wishing premade patties. Some of those outfits have become very competetive pricewise with mix your own.
