Improve Flavour and Flow with PG-Based Mixing
Propylene Glycol (PG) is used to carry flavour and improve liquid flow in DIY mixes. Its lower viscosity allows faster wicking, making it a key component in MTL pod systems and low-power devices.
PG is typically combined with VG, flavour concentrates and optional nicotine shots to create balanced e-liquids with consistent performance.
Why it matters: higher PG content increases flavour clarity and throat hit, while improving stability in smaller coils and refillable pods.
Supplied PG is nicotine-free unless otherwise specified and intended strictly for adult users (18+) in Ireland.

How PG Behaves in Real-World Use
Propylene Glycol (PG) improves liquid flow and flavour delivery in refillable pod systems. Its lower viscosity allows faster wick saturation, reducing dry hits in low-power setups.
Ireland note: PG remains stable in colder conditions, unlike high-VG liquids that may thicken and reduce wicking performance.

FAQ – Propylene Glycol (PG)
Is PG better for flavour?
Yes. PG carries flavour more efficiently than VG, resulting in clearer and stronger taste in MTL setups.
Why does PG feel stronger on the throat?
PG produces a more noticeable throat sensation, similar to traditional smoking, especially at higher ratios.
Can I use 100% PG in my device?
Yes, but it is typically used in blends. Pure PG may feel too sharp for some users and is usually mixed with VG.
For adult users (18+) in Ireland.
