Your fresh chestnuts should be stored in your refrigerator, ideally at 34-36F degrees. If stored properly, they should remain fresh for about 3 months. A damp paper towel in the storage bag also helps retain moisture. Chestnuts may even become sweeter 3 to 5 weeks after refrigeration due to the starch converting to sugars. Please do not leave your chestnuts sitting out as they will dry and lose freshness.
