Nut FAQs

Have a question about nuts? Perhaps you’re just plain nuts about nuts. You’ve come to the right place. Here are some answers to the most frequently asked questions about Diamond’s favorite subject — nuts!

(1) How long can I keep my Diamond nuts?

The shelf life of nuts depends on several factors: storage conditions, whether the package is opened or unopened, and whether they are shelled or unshelled. In general, the following applies:

Shelled Nuts
Pantry Unopened package - 24 months
Opened package - 18 months
Refrigerator Unopened package - 36 months
Opened package - 24 months
In-the-Shell Nuts
Pantry Unopened package - 9 months
Opened package - 7 months
Refrigerator Unopened package - 24 months
Opened package - 18 months

Not all nuts will stay as fresh as Diamond’s. Due to our state-of-the-art technology and refrigerated storage, Diamond nuts stay fresher longer than those of other brands.

As nuts age, they may become rancid and develop a “paint” smell. The best way to determine freshness is to smell and taste the nuts prior to using.

(2) How should I store Diamond nuts?

Nuts can be stored in the pantry or refrigerator. When storing opened packages of nuts, be sure to use an airtight, odorless container, as nuts can absorb odors of other foods. Nuts stored in the refrigerator will stay fresher longer.

(3) What about toasting Diamond nuts?

Toasting nuts adds extra flavor and crispness. For best results, toast in the oven or on the stovetop. Nuts toasted in the microwave do not develop as much flavor or crunch.

Toasting time depends on both the size and variety of the nut.

  • Oven Toasting: Spread nuts in a single layer on an ungreased baking pan. Place in 350°F oven and bake 5 to 12 minutes or until nuts are golden brown; stir once or twice until toasty and fragrant. Remove from pan to cool. Nuts will continue to brown slightly after removed from oven.
  • Stove-Top Toasting: Place nuts in a heavy skillet over medium heat and stir or toss continuously until nuts turn a golden brown and smell toasty and fragrant, approximately 3 to 8 minutes.
  • Microwave Toasting: Spread nuts in a single layer in a glass pie plate. Microwave on HIGH 5 to 6 minutes (check frequently; microwave ovens vary), stirring every 2 minutes. Cool.

(4) Can I find in-the-shell nuts year-round?

Walnuts are harvested in the fall and the new crop of in-the-shell, or inshell, nuts are found in grocery stores soon after that. Much of the crop is sold during the fall and winter holiday season. However, Diamond shelled products are available in stores year-round.
