This is a question that many people have. The answer is yes, flour can go bad. However, the shelf life of flour depends on how it is stored.
Shelf life of flour
If flour is stored properly, it can last for up to six months. However, if flour is stored in an airtight container in a cool, dry place, it can last for up to two years.
- all-purpose flour - up to 2 years
- bread flour - 6 months
- cake flour - 6-9 months
- whole wheat flour - 3-6 months
So, if you are wanting to store your flour for an extended period of time, make sure to store it in an airtight container in a cool, dry place. This will help to keep it fresh and extend its shelf life.
Signs flour has gone bad
There are several signs that indicate that flour has gone bad. The first sign is the presence of mold. Mold can grow on flour that has been stored for a long time or that has been exposed to moisture. If you see any signs of mold, do not use the flour and discard it.

Another sign that flour has gone bad is an off odor. If the flour smells sour or musty, it is likely that it has gone bad and should not be used.
Additionally, if the flour has a gritty texture or clumps together, it has most likely gone bad and should not be used.
If you notice any of these signs, it is best to discard the flour and get a new batch.
