What is the meaning of BB in drink label?

"BB" on a drink label stands for "Best Before". It indicates the date until which the manufacturer guarantees the quality and safety of the product when stored properly. It is not a safety date, and the product may still be safe to consume after this date, but the manufacturer cannot guarantee its original flavor, texture, or nutritional value. It is recommended to follow the "Best Before" date to enjoy the drink at its best quality.
