We're out of parmesan cheese and I remembered I had some nutritional yeast in the cupboard, and eons ago when I was vegan I used n.y. in place of parm. The stuff in the cupboard is newer, but could be 4-5 years old. Tastes basically right, I can't decide if the slightly off taste means it's off or I'm not used to eating it anymore.
Does anyone know if it spoils, or more specifically, its shelf life?
Re: Does nutritional yeast spoil?
Thanks! I ended up dumping it because I finally found online essentially what you said, and I knew it was at least 4 years old (cool dark place tho) and it was only maybe a third of a cup.
