Florida is expected to produce almost 1.3 billion gallons of orange juice this year. Grapefruit are grown in Arizona, California, Florida and Texas. Pink flesh can range in color from pale pink to ruby red. Pink and white grapefruit are equally sweet. The best way to pick grapefruit is by weight.
Grapefruit are about three quarters liquid, so the heavier the fruit, the more juice it contains.
Outer coloring usually has little to do with the quality of the fruit, but you should pick those that are firm but springy to the touch. Often you will see green spots on the grapefruit's skin. Degreening does not affect the taste of grapefruit. Grapefruit first originated in the West Indies and were brought to Florida in 1840. They are probably a cross between a pomelo and an orange.
