Guide to Flavor Chasing : What can affect E-cig flavor?

Usually, I am not particularly referring to E-cig flavor, as performance characteristic of an atomizer (although it is considered critical), not only because it is mostly of personal perception, but also due to severely depending on many factors (atomizer’s design, the set-up used, wattage, e-liquid, drip tips used).

Nine Factors That Affect E-cig Flavor

However, several factors, controlled by the atomizer’s design/construction characteristics/features and by your own setup and adjustments, are simultaneously involved in ensuring flavor’s characterization as a performance characteristic.

  • A first one affecting e-cig flavor is the adequate liquid-saturation of the sufficient quantity of the cotton used. This factor may mean that you should operate your atomizer at the limit of liquid-“over-feeding” your wick (BF RDAs just need squonking whenever you experience deterioration of flavor in your puff).  This factor also gives prominence to the way you setup your build. It also means that you’d better choose quality cotton, at least as far as absorbency is concerned.

  • A second factor is the efficiency of the incoming -to the deck- air beam. Efficiency means:
  1. how much of the air incoming through your airflow adjustment (as you draw your puff) is hitting your coil’s surface and with what velocity,
  2. how much of your coil’s entire surface is covered by it,
  3. how close to the deck’s air holes you can position your coil,
  4. how large is your coil’s dimensions in relation to the deck’s air holes,
  5. what is the position of your coil’s axis in relation to the deck’s air holes and their design shape, in relation to the intensity of your draw, to the deck’s available space and to the vaporization chamber’s space.

In fact, the incoming airflow beam inside the deck should uniformly hit the coil’s surface with enough air velocity (for not “breaking-up” into a vortex flow), covering as much as possible of the entire coil’s lateral cylindrical surface.

This can be ensured by a deck’s long/deep, “narrow” air-guiding channel (channels) of a total area almost equal to the side area of the coil, with its air output as close as possible to the coil’s surface. This condition can be fulfilled in conjunction to the appropriate close-positioning of the coil’s surface against the air-holes’ output on the deck or on the vaporization chamber.

Under such conditions, the air velocity/pressure is kept high at the air-channel’s output and close to the coils surface, leading to richer vaporization of the liquid used. Note also that, in the case of side airflow holes, to prevent a substantial percentage of the (incoming to the deck) air quantity to “escape” directly to your mouth without adequately hitting your coil’s surface (due to your intense draw of your puff), your coil’s axis should be placed slightly above the center of the air holes.

Moreover, it is known that the bottom air-feeding of the coil is the most “efficient”, since the incoming air hits the coil from underneath it and covers the entire lateral surface of the coil as the air is sucked up to the drip tip.

  • A third factor may be the small vaporization chamber, which substantially raises the heat inside the chamber (even at lower wattage), while, at the same time, concentrates/compresses the produced vapor (increasing vapor’s density).
  • A fourth factor is the design of the internal top of the vaporization chamber, more often as a dome. Such an internally dome-shaped vaporization chamber’s bell provides a smoothly-flowed compression of the produced vapor (with lighter vapor’s stirring), as it is guided to the chimney’s or drip tip’s input. The width of the dome’s outlet and of the chimney’s to the drip tip is also critical for uniform flow of vapor or for compressing/decompressing it accordingly.

Drip Tip
  • A fifth factor is the chimney and the drip tip. Important are the length/width of the chimney (its width area should be around the total area of deck’s air-outlet holes) and the design of the driptip’s internal air channel (height/width/shape) in conjunction to the vaporization chamber’s output or the chimney’s output area. Also, the way you close your lips around the driptip (tight or loose) is critical. Tighter lips lead to denser vapour inside your mouth (less air from the slightly open sides of your lips is mixed with the sucked vapour through the driptip). Thus, the outer diameter of the driptip (in relation to its inner diameter) is also critical, depending on the amount of the vapour produced.
  • A sixth factor is how close to your mouth is the vaporization’s source (the coil). RDAs are the best in this factor, providing richer flavor, because the coil is closer to your mouth and the produced vapor travels a shorter distance to your mouth, without any severe “manipulation” from the bell and chimney. In RTAs, the GTA-styled deck has been designed with this factor in mind.

Vape Wire
  • A seventh factor affecting the e-cig flavor is the type of wire used and its thickness. The more “complex” the wire construction is, the larger is its surface area impregnated by the liquid. This provides denser vapour.
  • An eighth factor is the coil’s pivot-core. Larger cores engage in vaporization larger available wick’s surface area. The number of coils used is also included in this factor (two coils produce more vapour than one, increasing vapour’s density).
  • The ninth factor is the wattage/temperature used for each specific coil and for each specific liquid used. Adjusting your wattage/temperature is the simplest way to alter the flavor you get from your liquid. Different flavor notes of each liquid are revealed at different temperatures and your power/temperature settings, in combination with your coil’s resistance, will determine how hot your coil gets.

Conclusion

From all the above, it is understood that the subject of flavour (taste & smell) is quite composite if it is to be objectively described. That’s why, in most cases, vapers just express their opinion of E-cig flavor, as a personal perception and judgement.

I am not in the vaping business. I found vaping as the escape door from my 25 years of smoker’s imprisonment. It just took me four days of attempting to totally get out of it, thanks to the appropriate –for me- “equipment” (includes e-liquids). Now, vaping “equipment” has become another one of my fields of interest, for helping others to discover, on their own, their personally appropriate “equipment”.
I am a hands-on enthusiast… by genes. I am triggered by everything that evokes any data already stored in my knowledge base, been a Physicist and an Electronics Engineer (for more than 35 years). I am intrigued by everything new that my knowledge-filter considers interesting enough to be analyzed for entering into my memory compartment. That’s why you will find me open-minded and out-of-the-box thinking. I have an urge for unfolding hidden “pictures” of design thinking on everything man-made.
