I can't find a good one. The one I havn't tried but i wanna is Rosetta (but judging by the other flavors....i dunno. it's a gamble). AF is fine for pineapple taste... it's decent, but not delicious. Pineapple is like pomegranate, just too mellow to duplicate.
Pineapple flavors, as a warning, do not taste like Fresh Pineapple. They taste like canned, warm pineapple that's been sitting in syrup. It will disappoint you.
I wanna mix it with some Coconut, make a Pina Colada.
. That's the only thing i could think of that it's good for.
