In the 4th century AD, the Romans introduced the walnut into many European countries where it has been grown since. The Romans use to call them Juglans Regia, meaning “Jupiter’s royal acorn”. Over time walnuts were traded along the Silk Road between Asia and the Middle East. Eventually they were traded overseas.

Farmers sweep the harvest floor for nuts that have fallen from the trees and then they send mechanical shakers to shake the rest of the trees to get the walnuts to fall. Walnuts are a very durable nut because of their outer shell and hull. After collection the nuts are sent to be hulled and dehydrated, this process helps protect the quality of the nut during storage.
