Can it sit out?
Buckwheat is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if buckwheat has gone bad
- A bitter, linseed-oil smell off the groats
- A damp feel and clumping in the bag
- Moth webbing stretched across the top of the container
When in doubt, throw it out.
Toasted groats (kasha) taste nutty and rounded; buckwheat that’s turned tastes sharply bitter, and one raw grain on the tongue tells you which you have.
