PG vs. VG E-Liquid - Which Is a Better Choice?

When it comes to selecting e-liquid, there are two main components to choose from, propylene glycol (PG) and vegetable glycerin (VG), and each one is formulated differently. Choosing the appropriate e-cigarette setup to suit your lifestyle requires the right formula in order to achieve the best performance and flavor, as each has its own unique characteristics.

Propylene Glycol (PG)
Propylene glycol, an organic compound that comes from propylene oxide, is recognized as safe by the U.S. Food and Drug Administration and was used by the military in WW2 to purify the air. Today, it is commonly used in solvents, humectants, food preservatives, tobacco products, pharmaceuticals and, of course, e-liquid.

Vegetable Glycerin (VG)
Vegetable glycerin is also considered safe by the U.S. Food and Drug Administration and is an all-natural liquid typically extracted from plant oils. It’s used in everything from cosmetic products to food production and e-juice.

5 Key Differences Between PG and VG E-Liquids
  1. Consistency - PG has a much thinner consistency than VG. This enables the liquid to soak into your wick and reach your coil at a much quicker rate, which is perfect for a pen-style e-cigarette. Because PG is much thinner, it will vape very quickly in a mod or RDA. VG, in comparison, is much thicker and takes longer to vaporize. This is great for mods, RDAs and tanks with larger coils, because they have more surface area to heat the liquid and typically vape at a hotter and faster rate. VG is often too thick for a pen-style e-cigarette, as it does not reach the coils fast enough, creating “dry hits” and shortening the life of the coils.
  2. Flavor - PG is essentially tasteless and carries your e-liquid flavor quite well. VG contains preexisting flavors and sweetness, which can sometimes dilute e-liquid flavor but will essentially make the flavor sweeter.
  3. Throat Hit - For someone transitioning from smoking to vaping, the throat hit is important. PG gives a stronger throat hit, much like a traditional cigarette. This can be a pleasant surprise for anyone transitioning from tobacco cigarettes. VG offers a much smoother vape, which is perfect for RDAs and mods because they are already operating at a higher and more powerful wattage.
  4. Sensitivity - The thicker consistency of VG e-liquid also helps to alleviate the irritation that is commonly seen with the higher-level PG e-liquids. Allergic reactions are also more common with the thinner PG e-liquids. If you've previously tried vaping with PG liquids and had throat irritation, you may find that a higher VG mix is more tolerable.
  5. Cloud Production - A higher level of VG e-liquid produces more vapor or “bigger clouds” and is a favorite of cloud-chasing vaping connoisseurs. Some vapers tend to be more discreet and would prefer the high PG liquid for this reason.
In summary, the answer to whether one is better than the other is wholly dependent on your personal needs and preference. If you tend to prefer a more discreet vaping experience and a throat hit more like that of a traditional cigarette, PG e-liquid is likely the better option for you. If you’re more of a cloud chaser, looking for the higher cloud production that’s a bit easier on the throat, than a higher VG level may be better suited for you. Whether you find PG or VG e-liquid to be a better choice for your lifestyle, understanding the differences between the two will make this process easier and more comfortable. Both types of e-liquids have different features and benefits, so you can choose the one that works best for you and your favorite vape device.
