VG/PG Explained: Key Ingredients in Vape Juice

VG/PG Explained: Key Ingredients in Vape Juice

Knowing the contents of vape juice is essential for new and experienced vapers alike in the vast world of vaping. Vegetable glycerin (VG) and propylene glycol (PG) are two of the most important ingredients. Let us go into the essential elements and reveal the subtle differences between these e-liquids, here you go through the VG/PG Explained details!

Vape Juice Ingredients

Understanding vape juice's overall composition is essential before diving into the intricacies of VG and PG. E-liquid, or e-juice, or vape juice, is a complex blend of four main components: flavourings, VG, PG, and nicotine (though it is also available without nicotine). When vapers inhale vapour during their activities, these vape juice ingredients work in concert to produce that vapour.

Vape juice formulation epitomises a delicate equilibrium of these elements, with each playing a vital role in sculpting the overall vaping experience. Among these ingredients, VG and PG serve as the cornerstone, instrumental in orchestrating vapour production, throat sensation, and flavour delivery.

VG and PG in Vape Juice

VG and PG in vape juice constitute the quintessence of any vape juice. They serve as the primary constituents, facilitating vapour production and accommodating flavourings and nicotine.

Understanding VG and PG

Vegetable Glycerin (VG)

VG, a derivative of vegetable oils, boasts a viscous consistency and subtle sweetness.

Renowned for its proficiency in generating voluminous vapour clouds, VG finds favour among aficionados inclined towards cloud chasing.

Compared to PG, VG is less predisposed to inducing allergic reactions.

However, VG occasionally dampens flavour nuances and might not efficiently carry nicotine as PG does.

Propylene Glycol (PG)

PG, a synthetic compound, remains colourless, odourless, and taste-neutral.

Exhibiting a thinner viscosity relative to VG, PG imparts a pronounced throat hit akin to traditional cigarette smoking.

PG excels in flavour dissemination, enriching the vaping experience with intensified taste profiles.

Despite its merits, some individuals might encounter allergic reactions to PG, manifesting as throat irritation or dryness.

VG/PG Ratio

An indispensable facet of vape juice formulation lies in the VG/PG ratio, delineating the equilibrium between vapour output, throat hit, and flavour intensity. Various VG/PG ratios, such as 70/30, 60/40, and 50/50, cater to divergent vaping preferences.

High VG (e.g., 70/30 or 80/20)

Crafted with cloud enthusiasts and sub-ohm vaping aficionados in mind, high VG ratios, such as 70/30 or 80/20, epitomise a realm of voluminous vapour clouds and velvety smooth throat hits. As vapour production takes precedence, these blends unleash a spectacle of billowing clouds, captivating the senses with their ethereal allure. However, amid the vapour extravaganza, flavour intricacies might undergo a subtle attenuation compared to their high PG counterparts. Nevertheless, for those enraptured by the mesmerising dance of vapour tendrils, high VG blends stand as a quintessential choice.

High PG (e.g., 50/50 or 60/40)

In stark contrast to their high VG counterparts, high PG ratios, such as 50/50 or 60/40, cater to aficionados yearning for a robust throat hit reminiscent of conventional smoking experiences. Armed with unparalleled throat sensation, these blends proficiently accentuate flavour profiles, bestowing vapers with a gratifying gustatory indulgence. Ideal for users prioritising flavour intensity and throat hit over vapour volume, high PG concoctions serve as a gateway to a sensory voyage imbued with nostalgia and satisfaction.

Balanced (e.g., 50/50)

Embodying a harmonious fusion of vapour production, throat sensation, and flavour saturation, balanced VG/PG ratios, such as 50/50, offer an oasis of equilibrium amidst the vast vaping landscape. Appealing to both novices and seasoned vapers alike, these blends encapsulate the essence of a well-rounded vaping encounter. From novice enthusiasts seeking an introduction to the vaping realm to seasoned connoisseurs yearning for a symphony of sensations, balanced VG/PG ratios stand as a beacon of inclusivity and satisfaction.

Vape Juice Composition

Comprehending vape juice composition transcends VG and PG exclusivity. Flavourings and, optionally, nicotine substantiate pivotal constituents, sculpting the quintessence of the vaping ordeal.


  • Flavourings imbue vape juice with diversity and complexity.
  • Spanning an extensive spectrum from fruity and saccharine to savoury and tobacco-infused, flavourings enrich the vaping milieu.
  • Quality flavourings accentuate the overall vaping escapade, endowing vapers with a satiating gustatory indulgence.


  • An elective ingredient, nicotine caters to vapers yearning for nicotine-infused experiences.
  • Graduated nicotine concentrations, ranging from 0mg (nicotine-free) to potent variants, accommodate diverse nicotine dependencies and preferences.
  • Selecting the appropriate nicotine strength is imperative, contingent upon individual inclinations and nicotine cravings.


In summation, VG and PG explained here epitomises pivotal ingredients in vape juice, each bestowing unique attributes upon the vaping experience. Whether one's proclivities lean towards voluminous clouds, flavour saturation, or throat hit emulation akin to traditional smoking, comprehending the dichotomy between VG and PG empowers vapers to tailor their vaping escapades with precision. Armed with discernment regarding the optimal VG/PG ratio and flavour amalgamations, each puff becomes an idiosyncratic odyssey, traversing nebulous vaporous realms and effervescent flavour landscapes.
