Burnt Vape Taste Explained With Simple Fixes

How to fix a burnt vape taste

Stop vaping. Puffing through a burnt hit usually finishes the coil off.
Check the e-liquid level and top up. When a tank or pod runs low, part of the cotton is left uncovered and those dry spots scorch first. Refill before it drops below a quarter full.
Leave it for 15 to 20 minutes. If it was a dry hit, the wick needs time to soak up liquid again. Then take one slow, gentle draw.
Check the power and airflow. Make sure the wattage is inside the range printed on the coil, and drop it a little. Open the airflow slightly so more cooling air gets to the coil.
Look at the cotton. Take the tank or pod off and look at the coil, if the wick is visible. Dark brown or black cotton, or a strong burnt smell, means the coil is done. Slightly dark but not charred might just be gunked up, and can recover after a rest and a refill.
Replace the coil if the taste hasn't improved. Burnt cotton can't be cleaned or reversed. Fit a new one from our replacement coils and pods and prime it before the first puff (steps below). If your kit runs on pre-filled pods, swap in a fresh one from our pre-filled vape pods.

Can you un-burn a vape coil?

Sometimes, if it was only a dry hit. Once the cotton has actually burnt, no. Which one you've got:

A mild burnt taste that came on suddenly after heavy use or when the tank ran low. Stop, refill, wait 15 to 20 minutes and try a gentle draw. If it tastes better, the coil is recoverable.
A harsh, acrid taste that doesn't improve after refilling and waiting. The cotton has burnt through, and there's no way to get burnt residue out of it. Replace the coil.
Burnt from the very first puff on a new coil. The coil wasn't primed, so the dry cotton burnt the moment it fired. Replace it and prime the next one properly.

A simple rule for replace versus rescue:

Every puff tastes burnt after a refill and a rest: replace the coil.
The cotton is visibly black: replace the coil.
Flavour has been fading for days and then suddenly tastes burnt: replace the coil.
One burnt puff that improves after waiting and refilling: you caught it in time.

Why a new coil tastes burnt, and how to prime one

A new coil comes with dry cotton. Fire it before that cotton is soaked and it burns on the first draw. The damage is permanent and the coil needs replacing. It's the single most preventable cause of coil problems, and priming before use helps prevent it.

Every coil needs priming on its own. A coil that worked fine doesn't make the next one immune, and it doesn't matter whether you'd used the coil for a day or a minute. What matters is whether the cotton was wet before the first fire.

Before fitting the coil, add two to three drops of e-liquid to each wicking port. Watch the cotton darken as it soaks in.
Fit the coil and fill the tank to the maximum fill line.
Set the device down and leave it for five to ten minutes so liquid soaks through from the tank side.
On a device with a fire button, take two or three slow draws without pressing it. This pulls liquid into the coil. Skip this step on a draw-activated device, because drawing on it fires the coil.
If your device has adjustable power, start at the lower end of the coil's recommended range for the first few sessions.

Pods with a built-in coil work the same way. Fill the pod and let it sit for ten minutes before you vape. Many pod kits fire as soon as you draw, so only take primer draws if your kit has a fire button or a way to stop it firing, and otherwise follow its instructions. Our guide to priming a vape coil goes through it in more detail.

Burnt taste by device type

Pod kits and pre-filled pods

A pod that isn't seated properly wicks badly and gets hot spots, so push it in until it clicks. On a refillable pod with a fixed coil, the whole pod gets replaced once the cotton burns. A pre-filled pod is replaced as a unit too: if it still tastes burnt after a rest, it's finished, so fit a fresh pre-filled pod.

Mouth-to-lung tanks and pod mods

Mouth-to-lung coils have a higher resistance and use less power, which makes them more forgiving. They work best with thinner, higher PG liquid such as our 50/50 e-liquids and nicotine salts. Very high VG liquid in a small MTL device wicks slowly and the cotton can't keep up. Check the coil is pushed fully in, because a loose coil wicks poorly too.

Sub-ohm tanks

Lower-resistance coils run at higher wattages and make warmer vapour, so they need thicker high VG e-liquids, good wicking and plenty of airflow. Chain vaping and hard pulls outrun the wick, and airflow that's nearly closed stops the coil cooling. Stay inside the printed wattage range.

Vaporesso XROS, XTRA and GTX coils

Vaporesso kits use the same cotton-wick coils as everything else, so the diagnosis is the same: dry cotton, a worn coil, or a tank run below its minimum level. A few model-specific checks:

XROS: a cartridge pod with a built-in mesh coil. Fill it through the fill port, close the port and wait ten minutes before the first draw. If it still tastes burnt after that wait, check the pod is clicked fully into the device and isn't letting air into the draw channel.
GTX coils (Target series and several pod mods): the side wicking ports need two to three drops each before fitting, then fill the tank and wait five to ten minutes. The 0.2 and 0.3 ohm GTX mesh coils are sub-ohm and run at higher wattages. Run them below their minimum and you get a muted, slightly off flavour rather than a true burnt taste, so turn the power up into the printed range.
XTRA: a compact MTL pod. Fill the pod and rest it for at least five minutes before the first draw. Its tight draw suits nicotine salts such as Bar Drop. Burnt on a new pod means it wasn't given enough time.
Worn coil: Vaporesso coils typically last one to three weeks depending on how often you vape and what liquid you use, and sweet liquids wear them out faster. If the burnt taste crept in over days rather than arriving on a new coil, order a replacement from our Vaporesso coils as soon as the taste goes slightly off, rather than waiting for a fully burnt hit.

What makes a coil burn

Coils are consumables. Depending on how you vape, the liquid you use and the coil itself, you'll get anywhere from a few days to a couple of weeks before performance drops. Muted flavour, darker liquid in the tank and a roughness on the throat that gets worse over time are the signs a coil is on its way out.

The usual causes:

An old coil. Very sweet or heavily flavoured liquids caramelise on the coil and shorten its life.
Chain vaping. Many puffs in a row, and the cotton can't draw liquid in fast enough.
Hard inhaling. On some devices it pulls in too much air and too little liquid.
Too much power. Above the coil's printed wattage range, the coil runs hotter than it was designed for and dries the wick.
The wrong liquid for the coil. Thick, high VG liquid in a small MTL device wicks slowly.
A tank or pod running low. Uncovered cotton scorches.
Airflow nearly closed. No cooling air, so the coil gets hotter.
A coil or pod that isn't seated. Poor wicking and hot spots.
A gunked coil. Some flavourings leave a sticky residue that burns at higher temperatures.

How to stop burnt hits coming back

Prime every new coil (steps above).
Refill before the tank or pod drops below a quarter full, and don't fire it when it looks nearly empty.
Match the liquid to the coil: thinner, higher PG liquid and lower power for MTL coils, thicker high VG liquid and higher wattage for sub-ohm coils.
Stay inside the wattage range printed on the coil, and turn it down if the vapour feels too hot.
Leave a few seconds between puffs so the wick can re-saturate, and take slower, steadier draws.
Give very sweet liquids a break between sessions instead of chain vaping them.
When the flavour goes slightly off, turn the wattage down a touch. A coil nearing the end tastes slightly less clean before it tastes burnt, and lower power stretches its useful life while you sort a replacement.
Clean the tank when you change flavours or coils so old residue doesn't burn onto the new one, and wipe any e-liquid off the contacts.
Pick a nicotine strength that suits you, so you're not tempted to chain vape.

Choosing the right coil and liquid

The label on a coil shows its resistance and a recommended wattage range. Lower resistance means warmer vapour, more power and a bigger demand on wicking and airflow. Higher resistance means less power, a cooler vape and more room for error, which is why it suits beginners.

For small starter kits and pod systems, 50/50 liquids and nicotine salts are kinder to the coil. For bigger sub-ohm kits, high VG shortfills wick well and give fuller flavour. Flavours that aren't loaded with sweetener last longer on any coil.

We stock replacement coils and pods for the popular kits, including Vaporesso, OXVA, Uwell, GeekVape and Aspire. If you're not sure which coil fits your device, contact us or bring it into one of our shops and we'll match you up.
