Africa’s biggest premium beer brand, Castle Lite, has launched lab-tested secondary packaging that will keep consumers’ beer extra cold for three hours without the use of ice after refrigeration.

Castle Lite, launched in 1994, is the only beer lagered at 2.5 °C and the lager’s clean crisp taste is best when served at sub-zero temperatures. Hence, Castle Lite continues to “push our innovations to deliver extra cold convenience”.

The brand launched its latest innovation, Cold Lock, in South Africa last month after four years of development. Cold Lock has been proven to be the only product in the world to keep beer extra cold for three hours without the use of ice after refrigeration.

This claim was verified by inspection, verification, testing and certification company SGS South Africa after the product underwent rigorous testing in 2018.
