How to Store Fresh-Milled Flour
Use fresh-milled flour within a few days at room temperature, refrigerate it for a couple of weeks, or freeze it airtight for months. It keeps the germ and its oils, which oxidise quickly, so cold, airtight storage preserves flavour and nutrients.
Milling your own flour captures flavour and nutrients, but it comes with a catch: fresh-milled flour is perishable in a way the bag from the shop is not.
Why it stales fast
Fresh-milled flour keeps the whole grain, including the oil-rich germ. Those oils start oxidising as soon as the grain is milled, so flavour fades and can turn bitter within days, unlike shelf-stable white flour, which has the germ removed.
How to store it
| Storage | Best-quality window |
|---|---|
| Room temperature (airtight) | A few days |
| Refrigerated (airtight) | A couple of weeks |
| Frozen (airtight) | Several months |

Frequently asked questions
How long does fresh-milled flour last?
A few days at room temperature for best flavour, a couple of weeks refrigerated, or several months frozen in an airtight container. Mill close to baking for the best results.
Why does fresh-milled flour go off faster than store flour?
It contains the whole grain, including the oil-rich germ, which oxidises quickly. Most commercial white flour has the germ removed, so it lasts far longer.
