VG Dominant – What It Means in Vaping E-Liquids

Definition

VG Dominant describes a type of VapeJuice“>vape juice that contains a higher ratio of Vegetable Glycerine (VG) than Propylene Glycol (PG). These e-liquids typically sit at 70 % VG or above, creating thick, pillowy vapour with a noticeably smoother Hit“>throat hit. Because VG is naturally sweet and viscous, VG-dominant blends are the go-to choice for Australian cloud-cheros who chase dense plumes and rich mouthfeel while keeping flavour relatively soft. They are ideal for sub-ohm tanks, rebuildable atomisers, and high-wattage Wattage (VW)”>Variable Wattage (VW) or Variable Voltage (VV) devices that can handle the thicker consistency.

Technical Details

VG is a plant-derived sugar alcohol with a viscosity of roughly 1.41 Pa·s at 25 °C, almost ten times thicker than PG. E-liquid makers therefore cut VG with distilled water or a small percentage of PG (usually 10–30 %) to balance wicking. Common “VG Dominant” ratios include 70/30, 80/20, 90/10 and even “Max VG” (95 %+). High-VG liquids have a lower refractive index, giving them a slightly cloudy appearance, and their boiling point (~290 °C) means they vaporise best between 180–230 °C. Coil mass should be 0.15–0.4 Ω with open airflow; cotton or mesh wicks need 20–40 % larger diameter channels to prevent dry hits. Nicotine strengths are typically 0–6 mg/mL because higher strengths become harsh when vapour volume increases.

Usage & Tips

  • Prime new coils generously; wait 5–10 min before first fire so the thick juice saturates fully.
  • Use 40–100 W on VW mods or 3.5–4.2 V on VV mods; start low and creep up until clouds form without spitting.
  • Clean tank weekly—VG caramelises faster and can darken coils; a quick warm-water rinse or ultrasonic bath extends coil life.
  • Store bottles upright in a cool dark place; high-VG liquids oxidise slowly, turning peach-pink. This is harmless but may mute flavour.
  • If you experience “vaper’s tongue,” rotate flavours or add 1–2 drops of distilled water per 10 mL to thin slightly.

Safety note: VG is hygroscopic—stay hydrated and keep equipment away from children & pets.

History & Context

When clearomisers ruled the early 2010s, 50/50 blends were standard. The rise of 0.5 Ω sub-ohm coils and Aussie cloud competitions around 2014 pushed mixologists toward 70 %+ VG, birthing the “VG Dominant” label now seen on almost every premium line Down Under.
