I like the smell of guava, it's very tropical and intoxicating, but even though I've tried to like it, I just don't really like eating the fruit. It's either too hard and astringent if not ripe enough, or when it is fully ripe it starts taking on a more putrid smell that is just somewhat offputting to me.
But if something like a Reisling varietal wine is said to take on the flavor of guava, that's a very positive thing. The fragrance is almost floral and edible at the same time.
