100% VG E-Liquid – What It Means & Why It Matters in Vaping

Definition

100% VG E-Liquid is a VapeJuice“>vape juice made entirely from vegetable glycerine (VG), with zero propylene glycol (PG). This high-VG e-liquid is prized for producing dense, smooth clouds and a naturally sweet taste, making it the go-to choice for cloud-chasing sub-ohm vapers and anyone sensitive to PG. Because it contains no PG, it delivers minimal Hit“>throat hit and is often used with Nicotine“>0mg nicotine or low-nicotine blends. In Australia, 100% VG e-liquid is sold nicotine-free under local regulations, allowing vapers to pair it with 18650, 21700 or Battery“>26650 battery mods for maximum vapour production.

Technical Details

VG is a thick, plant-derived liquid with a viscosity around 1.4 Pa·s at 25°C. 100% VG e-liquid typically has a specific gravity of 1.26 g/ml and requires larger wicking ports and lower-resistance coils (≤0.5Ω) to feed properly. Most manufacturers label viscosity in “%VG/PG”; 100/0 indicates no PG whatsoever. Variations include:

  • Flavoured 100% VG: flavourings suspended in pure VG rather than PG
  • Additive-free: no distilled water or ethanol thinning agents
  • DIY concentrates: VG-based nic shots that comply with Australian nicotine prescription rules

Because VG is hygroscopic, it absorbs ambient moisture, slightly reducing coil life compared with 70/30 blends. Temperature control mods can mitigate this by limiting cotton-dry hits.

Usage & Tips

Before filling, warm the bottle in your palm to lower viscosity, then shake vigorously—VG-heavy mixes separate easily. Use sub-ohm tanks or RDAs with wide juice flow and Cotton Bacon”>cotton bacon that can expand fully. Prime coils generously and start at 30–40W, stepping up slowly to avoid “spit-back”. If you experience dry hits, close airflow 25% and pulse-fire to re-saturate wicks. Store 100% VG e-liquid in a cool, dark place; refrigeration is fine but allow the liquid to reach room temperature before vaping to prevent condensation in the tank. Always check that your 510-threaded device can handle high-viscosity juice—some older clearomisers will flood or leak.

History & Context

100% VG e-liquid emerged in the early 2010s when competitive cloud-chasers sought bigger vapour than 50/50 blends could deliver. Australian import laws that restrict nicotine-containing e-liquids accelerated local demand for nicotine-free 100% VG options, driving manufacturers to perfect PG-free flavour concentrates and ultra-pure USP-grade VG sourced from certified rapeseed or palm.
