Luzona brand calamansi juice drink. A product of the Philippines. Purchased at A Dong Supermarket in West Hartford, CT.
Ingredients include water, calamansi extract, sugar, and citric acid.
Calamansi is a citrus fruit from the Philippines and southeast Asia that is usually described as a cross between tangerines and kumquats. The taste was surprisingly good, and seemed to me to be like a very slightly tart HoneyBell fruit, which is a hybrid between Dancy tangerines and Duncan grapefruits. Better than orange juice.
