I had one in Costa Rica that had coconut overtones. But I had it fresh from someone's land, and I don't know what variety it was if it was even a named cultivar. I just remember being very surprised at the flavor, very pina colada-esque. That person had lots of different fruit on the property, so who knows where they got it from, or if they developed it on their own.
The pineapples I had in Costa Rica were by far the best I've ever eaten anywhere. Aside from this coconut-y one, which had a yellow flesh, they were all usually very white flesh with a high acid content that started to erode my mouth because they were so good I had trouble not eating them every day! They were sweet, crisp, and fresh in a way that is hard to describe. I would love to be able to grow one here.
Costa Rica has some of the best soil and growing conditions in the world though, so that might account for the astounding fruit I had every single day for months there... perhaps it is not only due to the specific cultivars they grow. This was back in 1999, and I have not stopped thinking about their fruit since!
