Grapefruit varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common grapefruit varieties compare.

Variety	Best for
Ruby Red	Juice and breakfast halves: sweet, low-acid, deep pink flesh.
Pink (Marsh)	Fresh eating and salads: mild, juicy, and seedless.
White (Marsh)	Marmalade and sharper dishes: the classic tart-bitter flavour with pale flesh.
Oroblanco	Salads and segments: sweet, nearly seedless pomelo cross with low bitterness.

Which should I pick?

For juice and breakfast halves, Ruby Red is the sweet, low-acid default with deep pink flesh. No Ruby Red? Pink (Marsh) is a touch milder and nearly as juicy. Reach for White (Marsh) when you want a sharper, more bitter classic note, or Oroblanco for a sweet, nearly seedless segment in salads.
