Sanguinello

Sanguinello is a cultivar of the sweet orange (Citrus sinensis) notable for its crimson flesh, a trait shared by blood oranges. The fruit's exterior is typically orange with a lightly colored rind, while the interior ranges from pink to deep red, depending on climate and maturity. Sanguinello originated in Sicily, Italy, and it is now grown in the Mediterranean region and in other warm temperate areas where citrus thrives.

The red coloration develops in the juice vesicles when the fruit experiences cool nighttime temperatures during maturation, due to the production of anthocyanins. The fruit is medium-sized with a thin, smooth rind and a balanced, sweet-tart flavor that carries a hint of berry-like character. The flesh is usually seedless or lightly seeded, and the juice is vibrant and aromatic.

Seasonality for Sanguinello is winter, typically from December through March in many climates, with peak color and flavor occurring in the heart of winter. It is consumed fresh, used in salads and desserts, and pressed for juice or flavorings. Nutritionally, like other blood oranges, it provides vitamin C and various phytonutrients, including anthocyanins.

Sanguinello is one of several named blood orange cultivars, alongside Tarocco and Moro, and remains popular for its distinctive color and sweet-tart profile.
