Why Does My Vape Taste Burnt?
A vape tastes burnt primarily due to the coil or wick not being properly saturated with e-liquid, leading to what's known as a "dry hit." When the coil heats up without enough e-liquid to vaporise, it burns the wick, usually made of cotton, causing that unpleasant burnt taste. Other reasons include vaping at too high of a wattage, which can cause the coil to overheat, or using an old or damaged coil that needs replacing. Additionally, chain vaping (vaping continuously without giving the coil time to re-saturate) can also lead to this burnt flavour. Proper maintenance and use are key to avoiding it.
How Does a Vape Work Step by Step?
A vape works by heating e-liquid to produce vapour that users inhale. Here's the process step by step: First, the battery powers the device, sending electricity to the coil, a small heating element inside the vape. The coil heats up quickly when activated. The wick, typically made of cotton, absorbs e-liquid from the vape tank or cartridge. When the coil heats up, it vaporises the e-liquid soaked in the wick, turning it into an inhalable vapour. The user inhales through the mouthpiece, drawing the vapour into their lungs, where the nicotine and flavour are delivered. The process stops when the user releases the activation button or when the draw-activated device automatically powers down.
Vaping is typically used for smoking cessation and harm reduction - the latest evidence review by Public Health England concluded that E-Cigarettes are at least 95% less harmful than smoking tobacco cigarettes (1), even though a recent survey from Action on Smoking and Health (ASH) found that 40% of UK smokers wrongly believe vaping is as harmful or worse than smoking! (2)
Types of vapes
There are several types of vape kits, each catering to different user preferences and experience levels. Cigalikes are small, cigarette-like devices designed for simplicity, ideal for beginner vapers. Pod systems offer compact, user-friendly options with refillable or pre-filled pods and are popular for nicotine salt e-liquids. Vape pens are slim, pen-shaped devices with larger tanks and customisable options, making them a step up in complexity from cigalikes. Box mods or vape mods are more advanced, offering adjustable wattage, temperature control, and large battery capacity, favored by experienced vapers. Disposable vapes are single-use, pre-filled devices that are discarded after the battery or e-liquid is depleted, providing a hassle-free, maintenance-free experience. While disposable vapes are convenient, the issues surrounding them has led to the UK government's decision to ban disposable vapes in 2025 (3). Each type has its own features, making it important to choose based on personal needs and preferences.
What's in vape juice?
Vape juice, also known as e-liquid or e-juice, typically consists of four main ingredients: propylene glycol (PG), vegetable glycerine (VG), nicotine, and flavourings. Propylene glycol is a thin, tasteless liquid that helps produce a throat hit similar to smoking, while vegetable glycerine is thicker and adds sweetness, creating larger vapour clouds. Higher Vegetable glycerine content creates a thicker liquid so typically requires a high-power device, where propylene glycol creates thinner liquids, which is suitable for low powered vapes. Nicotine, if included, varies in concentration and provides the addictive component found in cigarettes. Flavourings come in a vast array of options, ranging from traditional tobacco and menthol to fruity, dessert, and candy flavours, allowing users to customise their vaping experience. Some e-liquids may also contain additives or sweeteners (4), but the core ingredients are generally safe when sourced from reputable manufacturers. However, the quality and safety of vape juice can vary significantly, so it’s essential to choose products from trusted brands.
Why Do Vapes Start to Taste Burnt?
Vape devices start to taste burnt mainly because of issues with the coil or wicking material. Over time, the coil, which heats the vape juice or 'e-liquid', can become clogged or burnt out, especially if used for long periods without proper cleaning or replacement. Another common cause is a dry hit, which happens when there isn’t enough e-liquid in the wick to vaporise, leading the coil to burn the cotton directly. This can occur if the e-liquid runs low, or if the device is used too frequently without allowing the wick time between puffs to absorb more liquid. Additionally, using a vape at too high of a power level can cause the coil to overheat, leading to a burnt, unpleasant taste. Proper care and maintenance, like replacing coils and keeping the tank filled, can prevent this issue.
Why Does My Brand New Vape Taste Burnt?
A brand new vape can taste burnt if the coil or wick wasn’t properly primed before use. When using a new coil, it's crucial to saturate the wick with vape juice by letting it sit for a few minutes before vaping. If you start vaping right away, the dry cotton wick inside the coil burns, causing a harsh throat hit, burning flavour and an overall bad taste. Additionally, using the vape at too high a wattage for the vape coil’s resistance level can also overheat the new coil, leading to the burnt flavour and potentially a nasty coughing fit! To avoid this, always prime the coil by soaking the wick, start at a lower wattage setting, and gradually increase it to prevent burning. Be sure to avoid lower-quality coils and ensure you aren't using the wrong resistance resistance coil for your device.
Why Is My Vape So Harsh?
A harsh vaping experience can be attributed to several factors. One common cause is using a nicotine level that’s too high for your preference, leading to an overwhelming throat hit. If you’re using a sub-ohm device with high nicotine e-liquids, this can also amplify the harshness. Another reason could be the coil's wattage setting; if the power settings are too high, it can cause the e-liquid to overheat, resulting in a hot, harsh feeling and nasty taste. Additionally, using poor-quality or high-PG (propylene glycol) e-liquids can contribute to a harsher throat hit compared to higher-VG (vegetable glycerin) liquids, which tend to be smoother. Lastly, if the coil is old or damaged, it might not vaporise the e-liquid properly, leading to an unpleasant experience. Adjusting your nicotine level, wattage settings, and ensuring you're using fresh coils can help mitigate the harsh throat hit.
Why is my vape too strong?
If your vape feels too strong, it could be due to a few factors, primarily related to nicotine strength and device settings. Using e-liquids with high nicotine concentrations can lead to an overwhelming throat hit and a strong overall sensation, especially if you're accustomed to lower levels. Additionally, if you’re using a sub-ohm device, the increased vapour production can intensify the strength of each puff, making the experience feel harsher. High wattage settings can also contribute to a stronger hit, as they heat the e-liquid more quickly and produce hotter vapour. To alleviate this, consider switching to a lower nicotine e-liquid, adjusting your device’s wattage, or using a device designed for a smoother vaping experience.
How to Fix Burnt Taste in Vape
If your vape kit is giving you a burning throat or otherwise tasting off (and your e-liquid is within it's expiry date), the first step is to change the replaceable coil, as a burnt or clogged coil is often the main culprit. If the replaceable coil is new, ensure it was properly primed by soaking the wick with e-liquid and allowing it to sit for a few minutes before use. Check that the tank has enough e-liquid and that the wattage setting isn't too high, as excessive heat can quickly burn the wick. You can also try taking slower, less frequent puffs to give the wick time to absorb more liquid. If the problem persists, cleaning the tank and ensuring no debris or old e-liquid is left behind can help improve the overall taste. Proper maintenance is key to preventing a burnt taste in the future.
Why Can't I Taste the Flavour in My Vape?
If you can’t taste the flavour from your vape juice, it could be due to several factors. One common reason is vaper’s tongue, a condition where your taste buds become desensitised to a particular flavour after prolonged use. Switching to a different flavour, staying hydrated or reducing your vaping frequency can help alleviate this issue (5). Additionally, an old or dirty coil can diminish flavour as it becomes clogged with residue over time, so replacing the coil or cleaning the tank may restore the taste. Low-quality e-liquids or expired e-juice can also result in a weak flavour. Lastly, vaping at a wattage too low for the coil might not produce enough heat to fully vaporise the liquid, leading to muted flavours. Adjusting the settings and using fresh, high-quality e-liquids can enhance the taste.
Why does my vape taste like cigarettes?
If your vape tastes like cigarettes, it may be due to a few reasons related to the e-liquid or the device itself. Some e-liquids are specifically designed to replicate the flavour of traditional cigarettes, particularly those labeled as tobacco flavours. If you're using a tobacco-flavoured e-liquid, it will naturally carry a taste reminiscent of cigarettes. Additionally, if the coil in your vape is burnt or old, it can impart a charred or ashy flavour that mimics the taste of cigarette smoke. Using low-quality e-liquids that contain impurities can also contribute to this acrid taste. Lastly, if you’re transitioning from smoking to vaping, it can be difficult to work out the right nicotine strength depending on your previous smoking habit, and your taste buds might still be adjusting, leading to a perception of similar flavours. Cleaning or replacing your coil and trying different e-liquids can help eliminate the cigarette-like taste
Could nic salt liquids be causing me issues?
Yes, nicotine salt (nic salt) liquids could be causing you issues, particularly if you're experiencing discomfort or strong side effects while vaping. Nic salt e-liquids typically contain higher nicotine concentrations, which provide a smoother throat hit and faster absorption compared to traditional freebase nicotine - though the legal maximum for retail liquids in the UK is 20mg/ml or 2%, regardless of whether it is freebase nicotine or nic salt liquids. This can lead to consuming more nicotine than intended, resulting in symptoms such as dizziness, headaches, or nausea, especially for those who are new to vaping or have a lower tolerance. Additionally, the smoother nature of nic salts may encourage users to take longer or more frequent puffs, inadvertently increasing their nicotine intake.
There are other considerations to be aware of when using nic salt liquids - at SMOKO we often have new customers coming over from using disposables complaining about breathing issues. This may be down to the fact that nic salt particles are larger than freebase nicotine particles, making it more challenging for the immune system to take care of which could lead to more fluid in the lungs from inflammation. Nic salt particles are also ionically charged, indicating that they have a harder time crossing into the blood from the lungs; this is in stark contrast from almost every brand touting that nic salts 'give you more of a nicotine hit' - the evidence actually indicates that vaping freebase nicotine results in higher nicotine blood serum levels (6). If you're experiencing problems, consider lowering the nicotine concentration in your e-liquids, switching to freebase nicotine, or adjusting your vaping habits to better match your tolerance.
Why Does My Vape Taste Burnt? Top Causes and Quick Fixes - Conclusion
Hopefully that covers the full range of possible causes for a burnt taste when you vape! In short, it's all about ensuring your e-liquid is of a high quality and within its use-by date, your coils and wicking material are in good condition and properly saturated before each vaping session. If these are all ok, then it may be worth using a lower power setting, and try to avoid 'chain vaping' to prevent the wicking material from drying out before taking another hit.
The great thing about prefilled options, like the SMOKO E-Cigarette cigalike vape and the SMOKO VAPE POD is that every refill contains a new coil, we fill our refills with our UK-made vape juice here in the UK so our e-liquid is fresh and not sitting on a plane, a boat or in storage before it comes to you. You don't have to worry about device maintenance; just charge your battery then place a new refill on it and you are good to go!
Making the switch has never been easier with SMOKO!
