What is 50/50 E Liquid?

In short, 50/50 e-liquid is vape juice with a balanced 50% ratio of the main e liquid ingredients; propylene glycol and vegetable glycerin. These ingredients are otherwise known as PG & VG and are important in helping you choose the right type of e-liquid for your vape kit or vape tank.

What Are PG & VG?

PG stands for propylene glycol. This is an organic compound in the form of a thick, colourless liquid with a slightly sweet taste. It is derived from vegetable oils and is used widely throughout the food industry. Propylene glycol is added to e-liquids as a thickener and base.

VG stands for vegetable glycerin. Is is very similar to propylene glycol in that it is odourless, colourless and has a faint sweet flavour. It also provides a base for vape juices but differs from PG in that it has a thicker consistency.

Why Do E-Liquids Contain Varying Ratios Of PG & VG?

Different ratios of PG & VG affect the viscosity or thickness of an e-liquid. As PG is thinner, e-liquids containing a higher ratio of PG will have a slightly more liquid consistency. VG is thicker, therefore higher VG percentages will produce a thicker e-liquid.

High PG (60%+)

Vape juices with more PG content are generally best suited to kits and tanks with coils at a higher resistance; anything above 1 ohm. These are often referred to as 'Classic' kits. The liquid is vapourised at a lower temperature and therefore thinner juice is required so that it can heat more quickly. PG also produces more of a 'throat hit' than VG. This combination of classic kit and high PG e-liquid will create a subtle, cool vapour with strong flavour.

High VG (60%+)

Vape juices with higher VG content are suitable for kits and tanks with coils at a low resistance; anything below 1 ohm, right down to 0.1 ohm. Lower resistance coils vapourise e-liquids at a higher temperature, therefore a thicker liquid is needed to slow the process. This also produces thicker, warmer clouds of vapour with more subtle flavour. This is known as 'sub ohm' vaping.


A 50/50 e liquid contains a balanced 50% ratio of both PG & VG. This makes for a well-rounded vape juice that suits the majority of kits and tanks.

High PG

Strong throat hit

Great flavour

Thinner vapour

Suitable for Classic (MTL) kits, tanks & coils (above 1 ohm)


Medium throat hit

Great flavour

Medium vapour production

Suitable for most vape kits, tanks & coils

High VG

Subtle/no throat hit

Good flavour

Thicker vapour

Suitable for Sub Ohm (DTL) kits, tanks & coils (below 1 ohm)

Why Choose a 50PG/50VG E Liquid?

As you can see from the comparison above, the great thing about 50/50 e liquid is that it offers a happy medium on throat hit, flavour and vapour production. They are versatile with balanced characteristics and most importantly, they're suitable for the majority of kits, tanks and coils.
