Brazilian Lemonade has a short shelf life. It is best when it is fresh because of the peels. It can continue to get bitter the longer it sits. However, If you removed the peels then it will last a couple of days in the refrigerator. As with any recipe that includes fresh ingredients, you should always inspect the lemonade for any signs of spoilage before drinking. If there are any off-odors, then discard it immediately.
