What is Yoshon?

The Torah (Vayikra 23:14) forbids using the new crop of grain (known as Chadash) before the second day of Pesach. Until this date only the past season’s produce may be used. Yoshon literally means “old” and refers to the previous season’s grains. This restriction applies to 5 types of grain (wheat, barley, oats, rye and spelt). There is a dispute between the Halachic authorities whether this also applies outside of Israel, and even in Israel, whether it applies to the crops of non-Jewish farmers. Many Halachic authorities rule that these restrictions do not apply outside of Israel, and consequently Kosher SA does not require our food services and manufacturers to adhere to these stringencies.

For those who wish to follow the more stringent opinion, we compile an ongoing list which will assist in making observance of this mitzvah (commandment) easier. The only way to avoid using any Chadash products containing these grains is by stockpiling enough of these products to last until Pesach. However, before Pesach arrives infestation may occur. Therefore, if you want to keep Yoshon, make sure to store flour etc. in the freezer and other products in a cool, dry place. Also check carefully for infestation before use.

Initially wheat flour, pasta, wheat grains, and cereals containing wheat are affected. Barley and oats become affected only later in the season. During the season (usually from October – April in the Southern Hemisphere), we issue regular bulletins as new information becomes available.
