Introduction
Vapes are an alternative to traditional smoking and have become successful, due to their ability to replicate the smoking experience without many of the harmful effects of traditional tobacco. At the heart of this experience is flavor, a key aspect that improves user satisfaction. This article delves into the various factors that influence the flavor of a vape, including e-liquid composition, vape device type, personal preference, and ten other aspects.
Propylene Glycol (PG) and Vegetable Glycerin (VG) Ratio
The base ingredient of any e-liquid is a mixture of Propylene Glycol (PG) and Vegetable Glycerin (VG), and the ratio of PG to VG determines the intensity of the flavor and the feel of the throat hit. PG carries flavors more effectively, while VG produces more vapor, and the ratio level between the two affects the vaping experience.
Here are some common PG/VG ratios found in vape liquids:
50/50 PG/VG: This is a balanced ratio that provides a good combination of throat hit and vapor production. It is suitable for most types of vape devices, including small, low-power devices and Pod systems. Those who are switching from smoking to vapes usually prefer this ratio.
70 PG / 30 VG: This ratio is popular because it provides a strong throat hit and enhances flavor clarity.It has a thinner consistency and is perfect for basic starter kits and mouth-to-lung (MTL) devices. But, it produces less vapor than higher VG ratios.
70 VG / 30 PG: A popular choice among sub-ohm vape smokers, this ratio provides a smoother throat hit and larger vapor clouds. The higher the VG content, the thicker the e-liquid will be, which works well in more powerful devices and direct-to-lung (DTL) vapes.
60 PG / 40 VG: This ratio is less common, but preferred by those who want a stronger throat hit and more pronounced flavor as well as those who use lower-powered devices.
60 VG / 40 PG: This balanced ratio leans more towards producing more vapor while still retaining a good flavor profile and throat hit. It is versatile and suitable for a wide range of equipment.
80 VG / 20 PG and higher (Most VG): Cloud chasers and those sensitive to PG have tailored these ratios. “Most VG” usually indicates the highest possible VG content in a mixture, which can sometimes be around 90% VG or more. Powerful sub-ohm devices best suit these very viscous e-liquids.
Flavorings
These chemicals give e-liquids specific flavors, ranging from tobacco and menthol to a variety of fruit and dessert flavors. The quality, type, and concentration of the flavoring agent play a crucial role in the flavor.
Nicotine content
The role of nicotine in flavor perception is twofold. First, it has a slight inherent peppery flavor, which can add to the complexity of the flavor. , the concentration of nicotine affects the throat hit, which affects the perception of flavor. Traditional nicotine has a more pronounced throat hit than smoother nicotine salts, which can affect the flavor experience.
Device and Coil Type
Different vape devices and their settings (power and temperature) can change the flavor experience. Higher temperatures can enhance the flavor, but if they are too high they can also lead to a burnt taste. The type of coil and its resistance level also play a role.
Device type
Different vape devices can affect flavor in different ways
Pod Systems: These systems usually have higher resistance coils and run at lower power. People often use them with nicotine salt e-liquids, designing them to increase flavor efficiency rather than to produce vapor. This design provides a more concentrated flavor experience.
Module and Sub-Ohm Tanks: these devices use lower resistance coils and can run at higher power levels. They can produce larger vapor clouds and can enhance certain flavors, but they can also alter or diminish subtle flavors due to increased heat.
Power and temperature
Power output (wattage) and temperature control settings can affect flavor.
Higher power/temperature: Increasing the intensity of the steam can bring out certain flavors more. But, too much power can result in a burnt flavor.
Lower power/temperature: provides a cooler vape that can better capture subtle flavor nuances without the risk of burning e-liquid.
Coil Material and Design
Material: Coils can be made from a variety of materials such as Kanthal, stainless steel, nickel, or titanium. Each material reacts to heat and can affect flavor.
Design: The design of the coils, such as single heating wire, dual heating wire, heating steel tubes, mesh coils, and ceramic coils, affects how well the vape oil heats up and vaporizes. For example, mesh coils have a larger surface area, more even heat distribution, and better flavor.
Coil Resistance
The resistance level of the coil affects the flavor of the vape.
High Resistance Coils: Mouth-to-lung (MTL) devices use these coils, which are higher than 1 ohm, to heat the e-liquid at a lower temperature. This heating method preserves the subtlety and complexity of the flavor and suits delicate or nuanced e-liquids especially well.
Low Resistance Coils (Sub-Ohm): Coils with a resistance of less than 1 ohm are used in direct lung (DTL) devices. They produce more heat and vapor, which has the potential to enhance certain flavors, especially sweeter, more intense ones.
Airflow
Devices with adjustable airflow can vary flavor intensity. Tighter airflow can concentrate flavors, while more open airflow can result in cooler, less intense flavors, but will produce more vapor.
E-cigarette oil compatibility
Certain devices and coils are better suited for certain types of vape liquids (based on their PG/VG ratio and flavor profile). It is important to match the vape liquid to the appropriate device and coil type for the best flavor experience.
The User’s Sense of Taste and Smell
Individual differences in perception and sensitivity to taste and smell will affect how a person experiences the flavor of a vape. This is influenced by factors such as smoking history and personal preferences.
Airflow and inhalation techniques
The amount of air mixed with the vapor (airflow) and the way the user inhales (mouth-to-lung vs. direct-to-lung) can change the intensity and nuance of the flavor.
Quality and age of the vape liquid
The quality of the ingredients and the manufacturing process affect the flavor. Over time, vape liquids can degrade or “steepen”, which can change their flavor profile – sometimes improving it, sometimes causing the flavor to diminish or change. Proper storage (in a cool, dark place) helps maintain flavor quality.
Maintenance and cleaning of equipment
Regular cleaning and timely replacement of coils and wicks are critical. Aging or burnt coils can impart a burnt or stale taste to the vapor, reducing flavor quality.
Conclusion
In conclusion, many factors such as the composition of the e-liquid, the type and settings of the vaping device, and the user’s personal preferences, all actively influence the flavor of vapes. Understanding these nuances is key to optimizing the vape experience, allowing users to customize it to their taste preferences. It also provides vape devices and e-liquid importers with a clear understanding of the purchasing and sales process.
