• 1. How long can I keep my Diamond of California® nuts?

  We guarantee our Farm to Table flavor up until the best before date printed on each package. To help ensure freshness, we recommend our products to be refrigerated after opening. Refrigerated storage of tree nuts helps to prevent the development of off flavors or rancidity. The ideal storage conditions are 45-55ºF in tightly sealed containers at 55-65% relative humidity.

• 2. How can I read the date code on your packages?

  The code below the Best Before date on the Diamond packages can be read as follows: Using 10120107331 as an example, the first 3 numbers, (101) reflect internal Diamond numbers, the next 2 numbers (20) indicate the year the product was packaged. The next three numbers (107) indicate the numerical day of the year (in this case the 107th day of the year). The last 3 digits are additional internal Diamond numbers. Thus, 10120107331, means the product was packaged on April 16, 2020.

• 3. What about roasting Diamond of California® in-shell nuts?

  Oven Roasting: Preheat the oven to 350 F. Spread in-shell nuts on a baking sheet and roast for 20 minutes. Then carefully remove one nut, holding it with a dish towel or pot holder, and crack it open. The meat should be lightly toasted and aromatic. If it still looks pale inside, roast a few minutes longer. Keep in mind that walnuts and almonds may take less time. Let cool, then serve.

• 4. Can I find in-shell nuts year-round?

  Most retailers opt to carry in-shell nuts for the peak holiday season only. Please refer to our store locator to determine what your preferred retailer stocks in their nearest location to you. Diamond shelled nut products are generally available in stores year-round.

• 5. What if I'm having difficulty finding one of Diamond's products?

• 6. What does Diamond do with the nutshells?

  Diamond Foods’ main processing facility in Stockton ends up with approximately 100 million pounds of walnut shells each year. None of these shells end up in landfills. All of Diamond’s walnut shells are sold to other industries, which use them in a number of ways: as a binder in sealants and glues, in sandblasting and cleaning, as an ingredient in cosmetics and as a fuel.

• 7. How can I remove the skins of nuts?

  To remove the skins of almonds and Brazil nuts, cover the nuts with cold water, boil, simmer 2 to 3 minutes, drain. Add cold water; drain. Pinch nuts to slip skins off. For hazelnuts, spread hazelnuts on a non-greased cookie sheet and place in a 275°F oven for 20 to 30 minutes, until skin cracks. Remove from oven and rub in a soft cloth to remove skins.

• 8. Why is there Rosemary Extract?

  In response to demand for products that are as simple as possible, we previously removed a preservative, and added an extract of rosemary to our nuts. A very small amount of this plant-based extract is applied to the nuts to help protect their delicate, fresh taste without adding any flavor or scent. You will know if the nuts that you are purchasing include this extract as it will be declared on the ingredient statement on the package.

• 9. Why are some of my walnuts darker in color than others?

  Color varies on the walnut kernels from light to dark. In spite of walnut color differences, there is no difference in quality. The darker color is usually caused by the position of the walnut on the tree. If the walnut came from the top of the tree, where it is exposed to the sun, then the walnut turns dark.

• 10. Are your nuts Kosher?

  All of our nuts are OU Kosher certified.  Read more here: https://oukosher.org/companies/diamond-foods/
