High VG – What is it in Vaping?

High VG: The Ultimate Glossary Entry

Definition

High VG refers to an e-liquid with a Vegetable Glycerin content of 70 % or higher. VG is a thick, naturally sweet liquid that creates dense vapour clouds and a smoother Hit“>throat hit. High-VG juices are designed for sub-ohm and high-wattagevaping, where large vapour production is desired. Unlike classic 50/50 blends, High-VG e-liquids sacrifice some flavour intensity for vapour volume, making them popular among cloud-chasing enthusiasts who pair them with low-resistance coils, ample heatsinks, and hybrid connection atomisers.

Technical Details

High-VG liquids typically measure 70 % VG / 30 % PG, 80/20, or even max-VG (90 %+). VG’s higher viscosity slows wicking, so rebuildable atomisers often use hot spot-free spaced coils, wide cotton channels, and increased heatsink mass to prevent dry hits. Most regulated devices set between 50 W and 150 W optimise vapour density without scorching the wick. Nicotine strengths are usually 0–6 mg/mL because the volume of vapour per puff delivers more nicotine; strengths above 12 mg can feel harsh or peppery. Temperature-control or stainless-steel coils help maintain consistent flavour at high wattages.

Usage & Tips

  • Priming:Drip High-VG juice directly onto the coil and wait 5–10 minutes after filling to avoid burnt hits.
  • Coil Care: Use coils rated 0.5 Ω or lower; spaced builds reduce hot spots and improve wicking.
  • Tank Choice: Select sub-ohm tanks with large juice ports and top airflow to minimise leaks.
  • Safety: Monitor high-wattage settings—exceeding coil limits risks battery strain and overheating.
  • Storage: Keep bottles in cool, dark places; VG thickens in cold weather, so warm the liquid gently if flow slows.

History & Context

High-VG e-liquids emerged around 2013 as sub-ohm tanks and high-wattage devices gained popularity. Australian vapers embraced them for competitive cloud tricks and smoother throat feel after nicotine import limits lowered strengths. Today, they remain a staple in the sub-ohm segment, constantly refined with new VG/PG ratios and flavour concentrates.
