Signs nutritional yeast has gone bad
- Clumping or a damp texture, meaning moisture got in.
- A faded, flat smell where there was a savoury, cheesy aroma.
- Any musty smell or visible mould.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store nutritional yeast
Nutritional yeast fears light and moisture, which fade its flavour and its B vitamins — keep it in an airtight, opaque container in a cool, dark cupboard, and scoop with a dry spoon.
