In the stores, choose big sized, fresh nuts.

To verify freshness, cut open some sample nuts and check for heavy, meaty, creamy white kernel inside since oftentimes it is difficult to find out damaged nuts by their outer appearance. Avoid nuts with greenish mold developed between the convoluted folds and the nut kernel and its outer shell. 

Chestnuts should be treated more like vegetables and fruits than nuts when it comes to their storage. Once at home; they sooner packed and kept in cold storage in the refrigerator, set with high relative humidity where they remain fresh for few weeks.
