In response to a question we frequently receive, here’s a quick explanation of how to read a Briess lot code. Each lot of malt we produce receives a unique six-digit lot code which represents the date of production. To determine the date, start from the left and read to the right of the code. The first two numbers correspond to the year that the product was manufactured. The second two numbers designate the month of production. And the last two numbers indicate the day of the month of production. Malt produced on May 2, 2012, would have a lot code of 120502. Some lot codes may include a letter or additional numbers after the six-digit code. Ignore them as they are for internal use only.
