How much Juice, or Sections are in a Grapefruit?

Grapefruit image

Many recipes require the juice of one grapefruit or 6 ounces of grapefruit sections. But exactly how much juice is in a grapefruit anyway? And how many sections are in a grapefruit?

In order to figure out how much juice and sections are in a grapefruit we selected a medium grapefruit, measuring about 5 inches (12.5 cm) wide and weighing a generous 1 pound for our test sample. On average, you can squeeze 1 cup of juice from 1 grapefruit and will find 12 fruit sections. Although used less often than an orange, lemon or lime, 1 grapefruit gives about 3 tablespoons of zest.

Did you know that grapefruits were first found growing on the Caribbean Island of Jamaica where they coined the term grapefruit because it grew in bunches like grapes. Today, the state of Florida produces about 70 percent of all the world's grapefruits. Unfortunately, despite their great benefits, grapefruits do negatively interact with certain prescription drugs. Grapefruits were among the first documented fruit to interfere with a drug given to chemotherapy patients, cholesterol lowering drugs, and a drug prescribed to transplant patients to lower organ rejection.

So now you can be confident that 1 cup is how much juice is in a grapefruit. To determine other correct grapefruit measurements, you can use the converter below. Having trouble juicing grapefruits? We highly recommended getting a hand juicer, such as the Bellemain Squeezer because it makes juicing grapefruits, oranges, lemons and limes so much easier. If you are struggling to get the zest off, look into a zester, or better yet a microplane, which will also work with parmesan cheese, nutmeg, garlic and ginger!
