A 100 VG e-liquid is a very high-vegetable-glycerine liquid, but the wording on a bottle still needs careful reading. “100 VG” may describe the carrier base rather than every ingredient in the finished liquid. Flavour concentrates, nicotine ingredients or processing aids can use other carriers, so do not assume that a front-label claim tells you the complete formulation.
The main practical issue is viscosity. Vegetable glycerine is much thicker than propylene glycol, which means a high-VG liquid can move through a coil’s wicking material more slowly. It may work well in hardware designed for thicker liquid, yet struggle in a small pod or a narrow, high-resistance coil. Before using one, check the device manual, the exact coil family, the recommended liquid ratio and the product label.
This guide explains how to evaluate 100 VG e-liquid in New Zealand without assuming that one ratio is suitable for every device.
What Does 100 VG E-Liquid Mean?
VG stands for vegetable glycerine, one of the main carrier ingredients used in e-liquid. PG stands for propylene glycol, the other common carrier. Both can carry flavour, but they behave differently inside a vaping device.
A bottle described as 100 VG generally signals that the manufacturer has avoided PG in the main base or has made the liquid as close to all-VG as its formulation allows. That does not automatically prove that the finished product contains no PG at all. The only reliable approach is to check the full ingredient statement or ask the manufacturer to clarify what the percentage covers.
This distinction matters for two reasons:
- A person avoiding PG needs evidence from the complete formulation, not just a product name.
- A person choosing liquid for hardware needs to know how thick the finished liquid is, not only the marketing description.
If you are comparing general ratios such as 50/50, 70/30 and high VG, start with our broader vape liquid NZ guide. The page you are reading is intentionally narrower: it focuses on the special compatibility questions raised by 100 VG liquid.
Why VG Changes the Way a Device Wicks
The coil does not pull liquid from the tank by force. Liquid has to move through small inlet openings and soak into cotton or another wicking material. The wick then keeps the heating surface supplied while the device is used.
VG has a substantially higher viscosity than PG. In everyday terms, it flows more slowly. Research into e-cigarette solvents also treats PG and VG as physically different liquids whose behaviour changes with temperature and mixture. That is why two liquids can perform differently in the same coil even when their flavour and nicotine labels look similar.
Several hardware details affect whether a thick liquid can keep up:
- Wicking-port size: Wider liquid inlets generally give thick liquid an easier path to the wick.
- Coil design: A larger coil head may contain more wicking material and larger openings than a compact pod coil.
- Power and heat: A coil that vaporises liquid quickly needs the wick to replenish just as quickly.
- Draw frequency: Repeated puffs with little pause can outpace slow wicking.
- Temperature: Thick liquids can become even slower-moving in a cold room, car or delivery box.
- Fill level and airflow: A badly filled or poorly vented tank can develop pressure problems that look like a liquid-ratio problem.
High VG is therefore not a simple synonym for “better clouds”. The coil and liquid must work as a system.
Which Devices May Suit 100 VG E-Liquid?
The table below is a starting point, not a substitute for the manufacturer’s instructions.
| Device or coil format | Likely suitability | What to verify |
|---|---|---|
| Larger sub-ohm tank with wide liquid inlets | Often the most plausible match | Exact coil code, marked power range, manufacturer’s ratio guidance |
| Rebuildable atomiser used by an experienced adult | Can be configured for thick liquid | Wicking, resistance, battery knowledge and leak control |
| Refillable pod with a low-resistance coil | Varies by model | Whether the manufacturer permits high VG and whether ports are large enough |
| Small refillable pod with a high-resistance coil | Often a poor match | Recommended ratio, inlet size and signs of slow wicking |
| Prefilled pod | Not applicable | Use only the supplied pod; do not refill unless the manufacturer specifically designed it for refilling |
| Closed cartridge or proprietary system | Usually not user-selectable | Only use compatible cartridges and liquids specified by the manufacturer |
A low resistance number by itself does not prove that a coil will suit 100 VG. Two coils can share the same resistance while using different materials, port sizes and recommended power ranges. Match the full part number and manufacturer guidance first.

A Compatibility Checklist Before Filling the Tank
Work through these checks while the device and coil are still clean. It is much easier to prevent a mismatch than to recover a scorched wick.
1. Identify the Exact Hardware
Write down the device name, tank or pod name, coil family and coil resistance. Do not rely on appearance. Manufacturers often produce several similar coils that do not fit the same housing.
2. Read the Coil Markings
A replaceable coil normally shows its resistance and may show a recommended wattage range. Stay within the range printed by the manufacturer. If the device is not adjustable, confirm that the coil is listed as compatible with that specific device.
3. Check the Liquid Guidance
Look in the product manual or manufacturer’s support page for a recommended PG/VG range. If the manufacturer recommends balanced liquid, using 100 VG is an experiment outside that guidance and may produce poor wicking.
4. Inspect the Wicking Openings
Small inlet holes and a narrow internal chimney suggest that the coil was designed around thinner liquid. Large exposed cotton ports can be more accommodating, but they still do not guarantee compatibility.
5. Prime a New Coil Properly
For a replaceable prebuilt coil, add liquid to the tank and allow enough time for the wick to become fully saturated before use. If the manufacturer instructs users to moisten exposed cotton directly, follow that method and avoid flooding the central airflow channel. Begin at the lower end of the marked power range and increase gradually only if needed.
6. Test Without Chain Vaping
Take a short draw, then allow the wick time to replenish. If the flavour becomes dry, harsh or unusually hot, stop. Continuing to fire a dry wick can permanently damage it.
Common Problems With Very High-VG Liquid
Dry or Burnt Taste
A dry taste is the clearest warning that liquid is not reaching the heating surface quickly enough. Stop using the device. Check the fill level, coil installation, power setting and wicking time. If the wick has already scorched, adding more liquid will not restore it; the coil or pod usually needs replacement.
Good Vapour at First, Then Rapid Flavour Loss
This pattern can appear when a fully saturated coil works for the first few puffs but cannot replenish between draws. Longer pauses may confirm the problem, but the lasting solution is a more suitable liquid or compatible coil rather than repeatedly pushing the same setup.
Gurgling or Leaking
Thick liquid is not immune to leaking. Flooding can follow incorrect filling, a damaged seal, a loose coil, condensation or leaving a tank in heat. It can also happen after trying to force liquid into the wick. Clean the device, inspect seals and reassemble it according to the manual.
Poor Performance in Cold Conditions
If a bottle or device has been kept in a cold place, let it return naturally to room temperature before use. Do not microwave, boil or apply direct flame to e-liquid. Rapid heating can damage packaging and create an avoidable safety risk.
The Coil Works but the Draw Feels Wrong
A liquid change can alter vapour density and airflow preference. Do not compensate by immediately exceeding the coil’s marked power range. Adjust within the manufacturer’s limits and make one change at a time.
Does 100 VG Mean PG-Free?
Not necessarily. The phrase may refer to the base, while flavour ingredients or nicotine solutions use a different carrier. Product naming is not a laboratory result.
If avoiding PG is important to you:
- Read the complete ingredient list.
- Check whether the manufacturer defines “100 VG” or “max VG”.
- Ask whether flavour concentrates or nicotine ingredients contain PG.
- Keep the written answer or technical sheet with the product details.
- Stop using the product and seek appropriate health advice if you experience an unexpected reaction.
This article cannot diagnose sensitivity or recommend a medical substitute. A health professional is the right person to discuss symptoms or ingredient concerns.
New Zealand Product and Label Checks
New Zealand’s vaping product notification system covers both products containing nicotine and products labelled nicotine-free. The Ministry of Health also sets packaging and labelling requirements for regulated vaping products. A high-VG description does not replace those obligations.
Before buying any e-liquid, an adult consumer should check:
- The product name and manufacturer are clear.
- The nicotine concentration is stated rather than implied.
- The ingredient and warning information is readable.
- The bottle has not been opened, damaged or relabelled.
- Batch or traceability information is present where supplied.
- The product can be matched to an appropriate notified-product record when relevant.
- The ratio and device guidance are detailed enough to make a compatibility decision.
You can browse our general e-liquid category to compare products that are currently listed, but a category link is not a claim that a particular 100 VG formulation is in stock. Check each live product page for its actual ratio and availability.
100 VG Versus More Common Ratios
| Ratio description | General behaviour | Common compatibility question |
|---|---|---|
| 50/50 PG/VG | Relatively fluid and often used in compact refillable systems | Is the nicotine strength appropriate for the device? |
| 70 VG/30 PG | Thicker, often associated with lower-resistance hardware | Does the coil support the ratio and marked power? |
| Max VG | Manufacturer-dependent; not a fixed universal percentage | What does this brand mean by “max”? |
| 100 VG | Very thick carrier profile | Is the finished product truly PG-free, and can the wick keep up? |
These are general patterns. Device-specific instructions take priority over a ratio table.
Frequently Asked Questions
Can I use 100 VG e-liquid in any refillable pod?
No. Some refillable pods may handle high-VG liquid, while small high-resistance pods may wick it too slowly. Check the exact pod or coil guidance before filling it.
Will a lower-resistance coil always work?
No. Resistance is only one specification. The coil family, liquid ports, recommended wattage, device output and wick design all matter.
Is 100 VG e-liquid safer than a PG/VG blend?
A ratio alone does not establish that a vaping product is safe. “100 VG” describes formulation and physical behaviour, not an absence of risk.
Why did my new coil burn with high-VG liquid?
Possible causes include insufficient priming, power set too high, repeated draws, a closed liquid-control system, incorrect coil installation or liquid that is too thick for the wick. Stop when a dry taste appears rather than trying to power through it.
Can I thin 100 VG e-liquid myself?
Do not add household liquids or unverified ingredients. Changing a commercial formulation can affect concentration, contamination risk and device performance. Choose a suitable notified product or obtain manufacturer guidance instead.
Is “max VG” the same as 100 VG?
Not necessarily. “Max VG” is a manufacturer-specific description. Check the actual percentage and ingredient statement.
Bottom Line
The right question is not simply whether 100 VG e-liquid is good or bad. It is whether the finished liquid is accurately labelled and whether the exact device, coil and wicking system were designed to handle it.
Confirm the formulation, match the full coil or pod specification, prime carefully and stop at the first sign of dry wicking. If your hardware is designed around a balanced liquid, choosing a compatible ratio is more sensible than trying to make an extremely thick liquid work.
