If you go through a lot of all-purpose flour in your household, you can keep it at room temperature in an airtight container for up to three months.
Whole-grain flours (wheat, rye, buckwheat, spelt) contain the oil-rich germ of the grain, which can quickly turn rancid. These flours, as well as any others you don’t use on a regular basis (pastry flour and semolina, for example) can be kept in the refrigerator for up to six months. Slip the original bag of flour inside a zip-top bag for easy, moisture-proof storage.

Rice and Grains
Keep oats, barley, rice, quinoa, and their kin in airtight containers in your cupboard for up to six months.
A Good Thing for Pantry Organizing: When transferring dry ingredients to glass jars, use an envelope if you don't have a small funnel nearby. Cut a generous triangle from one end of the envelope, then snip tip off corner, and open into a cone. For large amounts, use big manila envelopes.

Nuts and Seeds
Because nuts and seeds have a high fat content, they’ll turn rancid if kept at room temperature for too long. Your almonds, walnuts, pecans, pistachios, cashews, macadamias, pepitas, sesame seeds, and flax seeds will stay fresh for up to two months in the refrigerator and as long as 12 months in the freezer.

Your most frequently used oils -- olive and vegetable -- can be kept in a cupboard at room temperature for two months once opened, so don’t buy a bigger bottle than you think you’ll use in that amount of time. (A gallon of olive oil is no bargain once it goes bad!) Nut oils, and other varieties you use less frequently should go straight into the refrigerator once opened. Kept cold, your oils will be good for at least six months.

In the Freezer
In our test kitchen, all meat gets wrapped in butcher paper, followed by a layer of plastic wrap, and another of foil to protect it from freezer burn. Use it up within two months.
Fruits, vegetables, soups, and stocks also should be protected against freezer burn by sealing them tightly in a zip-top plastic bag or airtight container and used within about two months.
