Celsius energy drinks have gained popularity for their refreshing flavors and purported health benefits. But how long does Celsius last, and what affects its shelf life? Unopened cans of Celsius typically maintain their quality for about 1 year from the production date. Factors like storage conditions play a crucial role; keeping Celsius in a cool, dry place away from direct sunlight extends its shelf life. Once opened, it’s recommended to consume the drink within 24 hours for the best taste and efficacy. So, next time you wonder, “how long does Celsius last,” remember that proper storage ensures the longest enjoyment of these invigorating beverages.
