sweet is a sensation on the tongue , flavor comes  from the aromatic
compounds  , liberated by chewing, perceived  in the nose .

if you ever ate while really  hungry,  wild berries or fruits you will know
what flavorfull but not really sweet means .
wild grapes or even wine grapes is a good ex in comparaison with
domesticated table grapes , full of aromas while the latest is just sweet
but no flavor aromas .
