The Ultimate E-Liquid PG/VG Ratio & History
History of VG/PG E-Liquid Ratio
E-liquid is made up of two main ingredients propylene glycol (PG) and vegetable glycerin (VG). The ratio of PG/VG depends on who makes the e-liquid, in some cases you can pick your e-liquid PG/VG ratio.
When I first started vaping in 2008, e-liquid was made exclusively with PG, this is the base ingredient e-liquid companies in China used. At that time e-liquid made in the USA was very rare.
At the end of 2009 the FDA released a statement claiming that they had found diethylene glycol in electronic cigarette e-liquid. Diethylene glycol is a harmful ingredient used in the making of anti-freeze. You can read why that is not true in the following article, E-Cigarerre Myths.
Basically the whole âdiethylene glycol in e-liquidâ story was blown out of proportion due to the fact that PG (propylene glycol) is sometimes used in the making of anti-freeze. Hungry reporters were looking for a story, and I suspect big tobacco helped spread this misleading information. People started to associate propylene glycol (PG) with diethylene glycoil causing people to start requesting e-liquid without PG. I believe this is a big reason why we use VG in our e-liquid today.

Whats the Best PG/VG Ratio for my E-Liquid?
Currently almost all e-liquid comes with both PG and VG. If you make your own e-liquid or if you order e-liquid from a company that lets you select your own PG/VG ratio, itâs important to understand how each ingredient will affect your vape. Here is a simple list of the main benefits from both PG and VG.
Propylene glycol (PG)
- Increases throat hit
- Better flavor definition
- Thinner than VG, may wick faster
Vegetable glycerin (VG).
- Produces thicker vapor
- Has a sweet flavor
- Thicker than PG, may slow wicking
True 100% VG e-liquid is very hard to come by since most flavoring used in making e-liquid come with a PG base. Virgin Vapor does offer 100% VG e-liquid, there flavoring comes in a base of organic ethyl alcohol. I personally donât like a lot of VG in my e-liquid. I prefer an e-liquid that has defined flavor and a good throat hit over a somewhat thicker cloud of vapor. Anything over 50% VG and 50% PG is too much VG for me.
A lot of vapers like a 50/50 ratio, but I think the ultimate mixture is around 15-20% VG and 80-85% PG. Itâs nice to have a small amount of VG in the mix to help thicken the e-liquid and to create a thick and satisfying cloud of vapor. But if you add to much it will take away from the flavor definition and throat hit.
PG/VG E-Juice Ratio Conclusion
If you like e-liquid with defined robust flavor and an ever so satisfying throat hit, a mixture of 20% VG and 80% PG is perfect. For me anything over 50% VG is too much. See, I prefer to taste and feel the vapor over filling the room with such thick clouds I canât see my computer screen.
