Grapefruit is one of the most widely-planted and prolific citruses grown in Hawaii. The name alludes to clusters of fruit on the tree that often appear similar to grape clusters. The fruit is yellow-orange skinned and approximately 4-6” in diameter. The interior flesh is segmented and varies in color from white, yellow, and pink to red (generally, the red varieties are the sweetest).
Citrus trees require a well-drained soil and regular fertilization.
The taxonomy of Citrus genus is complex with cultivation dating back at least 2500 years. While the precise number of species is unclear, all originated from three primary ancestors: citron, pomelo and mandarin.
Grapefruit is rich in vitamins and minerals, especially vitamin C. Similar to all citrus, the peel contains aromatic oils and the fruit’s zest is used to add citrus flavor to recipes. The flesh is juicy, aromatic and acidic with a refreshing balance of sweet, sour and bitter notes.
