Want Bigger Clouds? Build Your Mix with High VG
VG is the key to dense vapour and smooth performance. Ideal for sub-ohm devices, it allows you to create thicker, softer e-liquids with reduced throat hit.
Used in DIY mixing to control vapour output and consistency across high-power setups.
Glycerin
How High-VG Liquids Behave in Real Use
Vegetable Glycerin (VG) increases vapour density but slows liquid movement due to its higher viscosity. In practice, this affects coil saturation, wicking speed and consistency across different device types.
Ireland note: in colder conditions, high-VG liquids become thicker, which may reduce wicking efficiency in smaller pod systems and require slower puff cycles.

FAQ – Vegetable Glycerin (VG)
Why does high VG produce more vapour?
VG creates thicker vapour due to its density, which results in larger visible clouds.
Why does high VG struggle in pod systems?
Its thicker consistency slows liquid flow, which can reduce wick saturation in small coils.
Is VG better for sub-ohm vaping?
Yes. High-VG liquids are commonly used in sub-ohm setups for increased vapour production.
Safety and Regulatory Context (Ireland)
Nicotine-free VG is not volume-restricted. Nicotine-containing products are limited to 10ml bottles with a maximum of 20mg/ml under Irish TPD regulations.
