Yoshon (“old”) refers to grain from the five species that took root before a given year’s Passover. Grain that takes root afterward is chodosh (“new”), which those who observe yoshon don’t eat until the following year.
What it means in practice
The key question is when the grain was harvested and milled. Observance varies by community.
