Grapefruit Oil is a mobile, yellowish to greenish yellow or pale orange yellow oil, possessing a fresh citrusy, rather sweet odor and a similar taste. As mentioned above, the bitterness particularly known from European and middle eastern fruits and peels, is no longer found in today's American grapefruit oil. The odor resembles that of sweet orange oil to a certain degree, but also has notes in common with bitter orange oil.
