Curing & Storing Chestnuts

Curing Chestnuts

Curing chestnuts enhances their sweetness as the starches convert to sugar and moisture gradually reduces. To check if your chestnuts are properly cured, gently press between the shell and the nut. Properly cured chestnuts will yield slightly under pressure.

Chestnuts ordered online and shipped to you undergo some curing during transit. This means they may already have started the curing process when they arrive. However, allowing them to cure further once received can enhance their flavor.

Storing Chestnuts

Farm Fresh Chestnuts typically arrive within 1 to 5 days from the shipping date. Store them in the coldest section of your refrigerator, within the provided mesh bag. Do not place inside an air-tight ziplock bag or they will mold. Chestnuts contain up to 60% water and are perishable, so it’s crucial to maintain optimal storage conditions. Ideally, they should be kept at temperatures between 33 to 34 degrees Fahrenheit with humidity levels around 90%. 

Freezing Chestnuts for Long-Term Use

For long-term storage, you have two options:

  • Uncooked Chestnuts: Freeze whole chestnuts in their shells. Place them in a plastic ziplock bag, remove excess air, seal, and freeze. They can be stored for several months.
  • Cooked Chestnuts: Cook the chestnuts first (see our cooking page for instructions) and then freeze them. Thaw in the refrigerator overnight and use promptly once thawed.
