How long will fresh squeezed lemonade last?

Fresh squeezed lemonade can be stored in the refrigerator for about 3 to 5 days when kept in an airtight container. However, its flavor and freshness may start to diminish after the first couple of days. If left at room temperature, it should be consumed within a few hours to prevent spoilage. For the best taste and quality, it's recommended to drink it as soon as possible.
