“Beyond nicotine satisfaction and cloud chasing, vaping is very much an exploration of our perception and appreciation of flavours,” says VAPORESSO. “How we perceive flavour is quite complex. From the perspective of taste, there are 6 flavours that can be categorised: sweet, sour, salty, bitter, pungent, and astringent. Not just linked to our tongue, flavour is also something you can smell. According to the NIH, humans can distinguish more than 1 trillion scents. It goes without saying then, that in improving refillable vaping devices, we are also pushing the frontier of flavour delivery.”
“While the vape juice provides the flavour, the vaping device is the key to unlocking and delivering it in the form of flavourful vapor. For years, scientists have been exploring how to fully unlock the full potential of vaping flavour.”
Dr Yu Zhou, a scientist from SMOORE Lab, said: “We’ve collected and tested thousands of liquids from the market just to discover how vaping devices can deliver the best flavour. We’ve come to some interesting conclusions from our research, but most importantly, we can say that flavour is the art of temperature.”
Dr Zhou has been working for years for SMOORE’s sub-brand, VAPORESSO, to continuously improve temperature control and its products’ flavour delivery.
“All vape devices from the beginning of vaping until now share the same basic heating mechanism. This includes some kind of storage for the e-liquid, a heating coil and a wick. When you heat up the coil in a device, the heat will vaporise the e-liquid from the wick, delivering it to the user.
“Typically, the range that users tend to vape at exists anywhere from 100°C - 315°C. But at the lower end of this range the vapour and subsequent flavour is pretty weak, and at the higher end puffs are harsh and the flavour can degrade from the PG breaking down into formaldehyde.”
Dr Zhou continued: “There exists a smaller temperature range in between these extremes- the ‘sweet spot’ if you may, in which users will experience ideal flavour delivery that is strong, and gives an accurate representation of the e-liquid’s flavour profile while remaining smooth. After thousands of tests with thousands of flavours from different manufacturers, we found that the zone of best flavour expression exists between 200°-260° C, depending on the juice.
“With the recently developed COREX technology, we hope to solve the problem of inconsistent heating and flavour delivery. Using a new MORPH-Mesh coil design with a greater surface area for heating, a larger ratio of the coil can reach the optimum flavour delivery temperature. For users, this translates to bigger, more flavourful clouds.”

VAPORESSO says you might have experienced that perfect flavour before, just to have it degrade over time as the cotton core loses its ability to retain liquid. While a step up from older silica-based wicks, organic cotton wicks still suffer from significant liquid retention degradation over time. Unfortunately, to find a cotton that sidesteps this issue, they had to go back to the drawing board.
“We’ve checked all cotton materials in the market but couldn’t find any that fit our requirements. So, we decided to make one of our own,” Dr Zhou continued.
In adopting the industry’s first 3D spunlace process, Zhou’s team succeeded in making a patented COREX cotton wick. Comprised of microfibers which give it a cloud-like fluffy texture and greater surface area, COREX cotton abstracts e-liquid more efficiently, thoroughly, and evenly compared to standard cotton wicks.
“According to lab tests, the COREX cotton’s flavour retention is 40% higher than that of traditional cotton, and has a service life 20 % longer than that of a traditional cotton core. For users, this means every puff carries the same flavourful punch, even after longer use.”

VAPORESSO adds that most vapers have experienced unwanted tastes from e-liquid being inhaled directly into the user’s mouth.
“While the flavour from vape juice can be pleasant in its vapor form, it can be overwhelming in its liquid form. While 100% leak protection is still a work in progress, several vape manufacturers have improved upon this issue, introducing several of their own proprietary leak protection technologies in recent years.”
Dr Zhou went on to add: “So far, we’ve managed to implement COREX technology in VAPORESSO’s LUXE X kit. From our lab tests, we can already see marked improvements, including a 50% increase in vaporisation efficiency ratio, a 50% increase in flavour and vapour reproduction, and a 50% jump in pod lifespan.”
VAPORESSO concludes that in the past 2 decades, vaping tech has been advancing at breakneck speed: “As the next generation of vaping development is upon us, what new advancements in the frontier of flavour can we expect? Whatever it may be, it will certainly be exciting to see.”
