What is Yoshon?
Yoshon literally means old. This is not to imply that products are labeled Yoshon are old in the negative sense.
Yoshon refers to the grain that had taken root before Pesach, when the Korban (sacrifice) Omer had been brought during the time of the Beis Hamikdash. This grain was permissible to be eaten. The grain that took root after, Chodesh, would be stored until the next year’s Korbon was brought before it too could be used.
Old used in the context of Yoshon refers to whether or not flour, specifically from Wheat, Oats, Spelt, Rye, and Barley, was planted prior to, or after the ’16th of Nissan’, which translates to the second day of Passover.
Flour from these grains planted prior to Passover is consider Yoshon, or old, under Jewish Dietary Laws. This flour is often used after harvest and milling. Flour from grains planted after Passover, or new, are sometimes not used until after the following Passover in order to comply.
