PG vs VG Guide
Understanding VG and PG in E-Liquid
Most E-Liquids are formulated with a combination of Vegetable Glycerine (VG) and Propylene Glycol (PG), along with food-grade flavourings. Nicotine may also be included, available in varying strengths depending on the device and user preference.
What Is VG (Vegetable Glycerine)?
VG is a plant-derived, thick liquid that produces dense vapour and contributes to a smoother inhalation experience. Due to its viscosity, VG may absorb more slowly into wicking materials—especially in smaller devices or pod systems. High-VG E-Liquids can cause faster coil buildup and may require more frequent coil changes.
VG has a naturally sweet profile and is commonly used in E-Liquids for sub-ohm or high-wattage devices designed for increased airflow and vapour output.
What Is PG (Propylene Glycol)?
PG is a thinner liquid that efficiently carries flavour and absorbs quickly into cotton wicks. It produces a stronger throat sensation ("throat hit") and is often used in lower-wattage or mouth-to-lung (MTL) devices. Some users may experience mild throat or mouth irritation with high PG content.
Choosing the Right VG/PG Ratio
The VG/PG ratio affects flavour, vapour production, and device compatibility. Higher PG ratios are typically better for smaller vapourisers and refillable pod systems, where fast wicking is essential. Higher VG content is ideal for high-power devices with larger coils and airflow capacity.
For example, a 40/60 PG/VG blend supports efficient wicking in compact devices, while Max VG formulations are better suited to sub-ohm setups. Max VG may not perform well in MTL or low-power devices due to its thicker consistency.
Vapourium E-Liquid Options
Vapourium offers a variety of E-Liquids, including Max VG and balanced PG/VG formulations to suit different hardware requirements. If you are unsure which ratio is best for your device, consult the manufacturer's specifications or contact our support team for factual assistance.
Frequently Asked Questions
What nicotine strengths are available in E-Liquids?
Freebase E-Liquids are typically available in strengths from 0 mg/mL (nicotine-free) up to 18 mg/mL. These are most often used with high-power, direct-to-lung (DTL) devices.
Nicotine salt E-Liquids are generally formulated in higher strengths, ranging from 10 mg/mL to 50 mg/mL. These are intended for use in low-power, mouth-to-lung (MTL) or refillable pod systems. Always use the correct nicotine strength and formulation suitable for your device type.
Are there any health considerations when choosing between PG and VG?
Individuals with sensitivities may experience mild irritation from either PG or VG. PG can cause dryness in the throat, while VG may lead to faster coil buildup. Users with known reactions should consult a healthcare provider or choose formulations tailored to minimise specific ingredients.
