Kishu mandarins are small fruits, averaging 2 to 5 centimeters in diameter, and have a round to oblate shape, about the size of a walnut. The mandarins are depressed at both ends, giving them a slightly squat appearance, and the rind is thin, smooth, and glossy. The rind also showcases a bright orange hue and is covered in tiny oil glands that release a light and aromatic fragrance. Kishu mandarins are easily peeled, revealing a thin layer of pith encasing small, divided sections. Each fruit may contain 7 to 14 segments and bears a semi-firm but tender, aqueous consistency. Depending on the variety, the dark orange flesh is also either found seedless or includes a few ivory seeds. Kishu mandarins have high sugar content, ranging from 11 to 14 Brix, a measurement of sugar within the flesh, contributing to the fruit’s candy-like sweetness. Despite their sugar content, Kishu mandarins also contain some acidity, creating a balanced, bright, sweet, and tangy flavor.
