What is in Vape Juice?  Discover More

Anyone who is looking to give vaping a try usually comes with some questions. There is a large amount of technology, vocabulary, and intricacies to consider when it comes to vaping, but things are not as confusing as they seem. The first, and possibly most integral, piece of vital information lies in what is in vape juice, or e-liquid. At Jvapes, all of our e-liquid is made, by hand, with the same basic ingredients and concepts, and every bottle will give you the basics of what you’re getting on the label. While most manufacturers follow the same principles, we can’t speak for every bottle of e-liquid you could buy. Still, though, let’s look at the label information, what it means, and what is in vape juice.

VG/PG Ratio – “Blend”

On each bottle, you’ll likely find “50VG/50PG,” or some variant of that. So, what are VG and PG? In a basic sense, they’re the only two ingredients that every, or nearly every, e-liquid is composed of. In a more technical sense, they’re two food-grade additives that are Generally Recognized as Safe (GRAS) by the FDA for oral consumption. The ratio represented here gives you an indication of the percentages of each liquid as they relate to each other, not the finished bottle, as a small portion of other liquids are added later in the process. For example: 100% of e-liquid in a bottle could be 90% VG/PG (45%/45% total in 50/50) with the remaining 10% of the finished product being flavorings and the optional nicotine. The VG/PG combination and nicotine strength of the bottle are referred to as the “blend.” For example: 70/30 (70VG/30PG), 18 mg. 

VG – Vegetable Glycerine

Vegetable Glycerine (sometimes referred to as Glycerol) is the ”vapor producing” half of the e-liquid equation due to the thickness of the liquid. It is clear and odorless, and produces a very smooth-to-the-throat vapor with a minor amount of inherent sweetness and flavor. Because of this, e-liquids with a higher VG balance can be a little sweeter, and taste a little different than flavors in another blend, though they’ll produce more, denser vapor with a smooth inhale (i.e. less of a “throat hit”). Vegetable Glycerine is named as such because it is produced from vegetable and plant oils.

Higher VG balance means:

Smooth vapor and flavor
Additional sweetness
Very dense vapor clouds

PG – Propylene Glycol

Propylene Glycol is another clear and odorless liquid, but it has no inherent taste even though is often found in sweet food items such as coffee mixtures and ice cream. It is thinner than VG, which thins out the end product by balancing or overtaking the VG portion. This means that e-liquids with higher PG levels are easier on coils and tanks, as the thinner liquid passes through easier. The makeup of PG is what contributes to the familiar “throat hit” of an e-liquid.

Higher PG balance means:

More throat hit
Less vapor output on exhale
Coils generally last longer


Because Jvapes has an AEMSA certified lab, we follow their guidelines for ingredients in all of our e-liquids, which includes flavoring. Per AEMSA’s requirements, all of our flavoring is GRAS grade for food additive products. One of the best ways to ensure that your e-liquid is produced with standard ingredient types and grades is to look for AEMSA certified labs.

Nicotine (optional)

Nicotine is an optional ingredient in all of Jvapes’, and most other companies’, e-liquid. In line with AEMSA guidelines, Jvapes uses USP certified grade nicotine with confirmed accuracy through titration to verify that the nicotine is accurate to the advertised percentage. Titration happens after VG, PG and nicotine are added to ensure that PG does not dilute the nicotine level below expectation.

So, What is in Vape Juice?

While the question of “what is in vape juice” can seem daunting at first, the actual makeup of a bottle of juice is easy to understand when you consider the parts individually. Vegetable Glycerin and Propylene Glycol combine together in a ratio that differs based on your preference, and flavors are added to what would be an otherwise purely sweet tasting liquid. In many cases, nicotine is added to the VG/PG mixture using an equation that ensures the output keeps the nicotine level accurate for your preference. While this is not an extensive description of each component, if you’re new to vaping, this is one of the best places to start as you gain knowledge of your juice and devices. Keep this in mind when it comes to flavors, if you’re finding one tastes different than you remember or expected, the VG/PG ratio and nicotine level can affect the final taste to a certain degree.
