Question: do chestnuts have to be refrigerated?
Answer: The ideal storage conditions for chestnuts are 33-35 degrees Fahrenheit and 85-90% humidity. ... Keep chestnuts refrigerated unless drying or sweetening the chestnuts. If black molds have entered into the chestnut kernel, do not eat the chestnut. Chestnuts can be stored in the refrigerator for 2 to 3 weeks.
