The light-green surface blemishes turn orange when the fruit is at its peak ripeness. A tangelo fruit is usually slightly larger than a grapefruit (but this varies) and has fewer seeds. The flesh is very juicy and tends towards the sweet side of the tangerine rather than the bitter side of its grapefruit lineage, with a fragrant rind. The taste is often described as more sour than an orange and less bitter than a tangerine, however, and is more commonly guessed to be a lemon-tangerine hybrid. The fruit is seasonal from December to April. It is distributed in the United States and Europe between November and April, and is on occasion available from July to September.
