Brian:
As Bob and Mark have already pointed out, CA Central Coast Chards, which are generally cooler climate growing areas which also have an edtended hang time for fruit, are pretty reliable in producing the pineapple/tropical aromas and flavors. Specifically, Monterey is the one spot that does it most often, for me. I also get distinct banana notes from some Monterey Chards, btw.
When those Chards are overdone with wood, it usually represses the tropical fruit, and you can end up with some mucky butterscotch kinda stuff...but many of the Monterey/Central Coast producers have figured that out (and the public has helped them with feedback
), so we're seeing less of that sort of egregious mistreatment.
