Yes, you can. Keep continuously refrigerated lemonade, keep it for 7 to 10 days after opening. If you want to extend the shelf life of opened lemonade, you will need to freeze it. To freeze, you can store it in an airtight container and leave it at least ½ inch headspace at the top. This will help lemonade expand when frozen. So, in this way, you can freeze this syrup for days, and still, it will feel fresh whenever you drink it. Hope this method will help you in the right way to freeze syrup. To get your hands on the best syrup, we will recommend you to get it from Shops.ae.
