Freeze drying maintains nearly all the nutrition of the preserved product, without dependance on electricity or temperature for storage. Wild harvested from private property (only!), our maitake is sold by volume, not weight. Freeze dried mushrooms weigh a fraction of their fresh weight. Each package is 1/4 (0.25) cups.
Please note that the product image shows the mushroom immediately prior to harvest, this is POWDER, not pieces or whole maitake.
