Fellow grapefruit haters -- go ahead and try Oasis. I taste citrus but it doesn't taste like grapefruit to me. If I had to guess, I'd say orange although there is a bit of a tang.
Overall, even though I can taste the prickly pear as well, I think it is too subtle a flavor for me. I like a little more flavor in my flavor.
Also, for you grapefruit haters... Know that Wild Passion is most definitely grapefruit. I like grapefruit, but it is a bit too much, even so. I had hoped that (like the description says) it would be mostly passion fruit, with a touch of grapefruit, but that's not what I get at all. Mine is several (maybe even 6 or more) months old, so there's always the chance that the balance has changed, but it is most definitely grapefruit, and not even ruby red.
It's amazing!
I have my cart waiting for a sale and always forget the time difference.
