Review of Guanabana Flavor-FLV:

I've never eaten a guanabana, but have had the Jumex brand nectar juices and enjoyed the flavor.  This wasn't identical to that, but it is still a really nice pleasant lightly tropical flavor and I'm definitely getting a little coconut flavor from this.  I'm unsure if that's authentic or not, but assuming you don't mind that note, this is a really nice flavor, and I can see this mixing well in tropical mixes.  Used to make Sour Taffy.
