How to choose Grapefruits

Look for firm grapefruit that yields slightly when pressed. Avoid overly hard grapefruit as this is a sign of drying, and avoid overly soft grapefruit with a sharp pungent smell as this is a sign of rotting.

How to store Grapefruits

Grapefruits can be stored in the refrigerator and will last 2-3 weeks.

Climate and origin

Grapefruits are thought to have originated in Barbados as a cross between an orange and a pomelo. Today grapefruits are grown in tropical climates around the world. (Zone 9-10 in the U.S.)


Grapefruits have a tart acidic taste with a juicy texture.

Miscellaneous information

The seeds of the grapefruit are very high in antioxidants and may have anti-microbial properties.
