How long can apple juice go unrefrigerated before it goes bad?

Unopened Apple juice can typically be left unrefrigerated for about 1 to 2 hours without significant quality loss. Once opened, it should be refrigerated and consumed within 7 to 10 days for optimal freshness. If left out for more than two hours, especially in warm conditions, it’s best to discard it to prevent the risk of spoilage and foodborne illness. Always check for signs of spoilage, such as off smells or changes in appearance, before consuming.
