How can you bring out the best flavour?
To stop vaping bland mist that tastes like boredom, you need to reduce the airflow to concentrate the aromas. Move your coil closer to the air intakes for direct impact. A reduced chamber is like a good espresso: it's better when it's concentrated. And for pity's sake, change your cotton before it turns charcoal black!
Technically, flavor depends on the fine vaporization of the liquid. A build with an optimized heating surface combined with a reduced atomization chamber increases the density of flavored vapor. Less air usually means warmer, denser vapor, which is ideal for revealing the complex notes of your favorite juices.
