Gall nuts are spherical growths found on oak trees. Their development is triggered when insects puncture tree branches and twigs where they then deposit their eggs. When the larvae hatch, they feed on the tree and secrete an irritant. Galls are the plant’s defense mechanism. As they grow, they provide shelter and food to the larvae until they reach maturity and are able to chew their way out. To preserve as much of the tannin as possible, galls were harvested preferably before the insect had become an adult and made its way out. At this stage, the galls are referred to as green galls’. They are small, heavy, and dark in color. ‘White galls’, gathered just before or after the insect has escaped, are bigger, lighter in weight and color, and contain fewer tannins. The holes through which the insects escaped are generally clearly visible. After separate the different colors of the oak gall, we pick the damaged one.
