Nutritional Yeast OR Brewer's Yeast? WTF!

My local health food store sells nutritional yeast in bulk. However, they insist on labeling it as "nutritional yeast or brewer's yeast." Is this a yeast lottery? These are two different products and I don't want the bitterness of brewers' yeast upsetting the delicate balance of my mac and cheeze. I long for the original packaging even if I pay a bit more. Call me risk averse.
