If the product is Sweetened Kumquat Nectar, the energy rises to 60 calories per 100 ml because producers blend in cane sugar to balance the tart flavor profile. Kumquat Green Tea yields 42 calories per 100 ml since the addition of tea is offset by light amounts of cane sugar. When carbonated water is injected to produce a Sparkling Kumquat Drink, the value decreases to 35 calories per 100 ml because the gas takes up physical space in the container.

The botanical origins of kumquat juice trace back to East Asia, where the raw Citrus japonica shrubs grow natively. Early Asian societies gathered the fruits during the winter, pressing the whole fruits into juices and drying the peels in the sun to preserve the harvest. The bright orange liquid became a staple in early Asian kitchens as a natural flavoring agent. The plant was brought to Europe in the 19th century. Today, modern processing allows the fruit to be pressed and bottled globally for commercial consumption.
