Quick Answer
Store milled flour in an airtight container, away from direct sunlight and moisture, at a consistent temperature below 70°F (21°C), and use it within a week for best flavor and nutrition.
Storing Milled Flour
To maintain the freshness of milled flour, it’s essential to store it in an airtight container. Glass jars with tight-fitting lids are ideal, as they prevent moisture and light from entering. A 1-quart (1-liter) jar is a good size for a week’s worth of flour for a small family.
Temperature and Location
Store the jar in a cool, dark place, such as a pantry or cupboard. Avoid storing milled flour near a heat source, oven, or stove. An ideal storage temperature is below 70°F (21°C), which helps slow down the staling process. For every 10°F (5.5°C) rise in temperature, the storage life of flour decreases by half.
Handling and Freshness
When handling milled flour, use a clean scoop or spoon to prevent contamination. Transfer the flour to the jar in small batches to maintain freshness and prevent moisture from entering the container. Milled flour typically remains fresh for 1-2 weeks, but it’s best consumed within a week for optimal flavor and nutritional value. Once opened, transfer any unused flour to an airtight container or freezer-safe bag and store it in the freezer for up to 3 months.
