Your tongue can only taste sweet, salty, bitter, sour and some msg flavor called savory (or some Japanese word isntead). That's it that is all your tongue can taste. Everything else is aroma. So any berry or fruit flavors would just be a bit of sweet/tart on the tongue and the whole rest of the flavor is the aroma.
Cigarettes blow themselves all over you so you can't help smelling them. Ecigs do not do that unless you remember to let your nose have some vapor. So try to remember to left some vapor waft out of your mouth every few vapes so your nose can smell it.
if you want more flavorful juices, some vendors offer extra flavor (like FreedomSmokeUSA offers extra flavoring on many juices, Flavor Splash on some others). And I think the juices I've tried from MadVapes and Velvet Vapors seem to have more flavoring than than the amount some other juice mixers use. More flavoring should add more aroma.
