Expiration & Storage Tips
When does buckwheat flour expire?
Unopened buckwheat flour had a long shelf-life of about a year from the purchase date if stored properly. Once opened, it's slightly less, about 6 months. Unlike plain wheat flour, buckwheat flour contains fat, which can cause it to go rancid faster. If you choose to freeze it, this extends the shelf life by additional 6 months to a year, allowing you to enjoy it for much longer.
How do you tell if buckwheat flour is bad?
To tell if your buckwheat flour has gone bad, give it a good sniff. If it smells sour, musty, or otherwise off, it's probably gone bad. Additionally, if you notice any discoloration, mold or clumping, it's a good sign that your flour has expired.
Tips for storing buckwheat flour to extend shelf life
• Always store your buckwheat flour in an airtight container.
• Try to keep it in a cool, dry place, like a pantry. Heat, moisture and direct sunlight can spoil flour faster.
• Consider storing it in the fridge or freezer to extend its shelf life. If you choose to freeze it, ensure it's in a freeze-safe container or bag to prevent freezer burn or moisture contamination.
• Always use clean, dry tools when measuring out your flour, as introducing moisture can cause it to spoil quicker.
