Grapefruit Juice

What is a Grapefruit?

A Grapefruit is a large citrus fruit belonging to the same family as oranges, lime and pomelo. Grapefruits are classified as white or blond, pink, or ruby. This doesn’t depend on their skin color but rather on the color of their flesh. They are usually four to six inches in diameter, with some types having seeds while others are seedless. Scientifically called Citrus paradisi, grapefruit has a juicy, tart, tangy taste and an underlying sweetness that as a whole produce a paradise-like flavor.

The good thing is, grapefruits are available throughout the year but they are in season from winter through early spring.

History of Grapefruit

Several botanists have thought at that time that grapefruit was the result of a natural cross breeding between other two citrus fruits – orange and pomelo.

In the early 19th century, grapefruits were cultivated in Florida but didn’t  immediately become a viable commercial fruit until later that century. Today, the major producers of grapefruits in USA include Florida, California, Arizona and Texas. Grapefruits are also sold in the markets of Israel, South Africa and Brazil.
