Find the Date Code stamped on your product's package. This may be a "Best By" date, or a production date code. If the date on your package is earlier than that listed for the product on our site, it is considered Yoshon. If it is the same or later, it is Chodosh.
For factory production codes (when applicable), the code is described on our site, as related to the date. A lower number is Yoshon, and the same or higher number is Chodosh. For a complete description on reading Date Codes, see our article "Date Codes Explained".
