Depending on the ratio of PG and VG, e-liquids can have different taste properties and provide a different sensation to users. PG and VG affect, among others, such features as the throat hit, final taste, cloud size during vaping, and allergy risk. Compare the characteristics of PG / VG in the graphic below.
The most common PG/VG ratios
Products based fully on propylene glycol hit vaper’s throat in a similar way cigarettes do. PG provides great flavour distribution and mixing. PG nicotine bases are ideal for taste enthusiasts and those trying to quit smoking.
As opposed to PG based products, vegetable glycerine nicotine bases bring a much lighter “throat hit”. VG is also responsible for cloudiness, therefore vapers who prioritize thick and white clouds ought to reach for them.
Nicotine bases with such ratio will leave vapers with a more noticeable throat hit and simultaneously very good flavor dissolution but also allow them to still enjoy those loved-by-all thick clouds.
Perfection when it comes to balancing between „throat hit”, taste and clouds. Nicotine base 50 propylene glycol / 50 vegetable glycerine may also work excellently for those who waver what to choose.
Perfect solution for those who seek very cloudy vapors but do not want to give up good-tasting e-liquids. In this case, the PG/VG ratio of 30/70 puts it halfway between 50/50 and 100% VG nicotine bases
PG/VG for specific vaping devices
Although every e-liquid can be vaped with e-cigarettes and MODs, there might be a difference in experience regarding the device one uses.
As mentioned above, propylene glycol is responsible for flavour distribution and glycerine for cloudiness, due to its’ higher viscosity. Therefore, to get the best experience, one should have a device appropriate to the ratio.
There are MODs and PODs. The first type devices are bigger with RTA / RDTA / RDA atomizers. The second type are smaller devices with evaporators matched as a cartridge with replacable coil.
PODs for PG
It is recommended to use thinner e-liquids for PODs. They have smaller coil, e-liquid carrier (cotton) and holes through which the carrier is soaked. Using thicker liquid can lead to drying the carrier and overheating the coil. In this type of devices the taste is delivered worsely, so the more PG, which is responsible for the taste delivery, the better the experience.
MODs for VG
In these devices there are bigger evaporators, coils, and as a consequence, there is a bigger air flow. Therefore, vapers use MODs when they focus on thick clouds which are brought by glycerine in e-liquids. Due to more coils and bigger clouds, the taste is clearer, which means there is no such a big demand for PG content. Moreover, because of MODs’ size, they have more fluid carrier and bigger air holes. Hence, e-liquid carrier will get soaked faster and dry slower.
Ratio matters, but so does the QUALITY!
When buying semi-finished compounds for e-liquids, you should always pay attention to the quality of the raw materials. Probably the worst thing any e-liquid manufacturer can do is to waste great quality pure nicotine and mix it with subpar, low quality, cheap VG or PG.
