If you’ve ever used a vape and encountered a strange, unpleasant "burnt" taste, you're not alone. Many vapers describe this experience as an off-putting and irritating sensation that can make the whole vaping process unenjoyable. The phenomenon of burnt vape taste, often referred to as "dry hit" or "burnt hit," can occur for various reasons, and understanding why it happens is key to preventing it. Here's a deeper look into the factors behind this issue and how to avoid it.
1. Understanding the Basics of Vaping
Vaping works by heating a liquid (e-liquid or vape juice) that contains nicotine, flavorings, and a base of propylene glycol and/or vegetable glycerin. This liquid is vaporized by a coil, which is part of the heating element in a vape device. When functioning properly, the coil heats the liquid to the point where it turns into vapor, which the user inhales.
The "burnt" taste occurs when the coil starts to burn the wick or the e-liquid itself, rather than vaporizing it properly. This typically results in a harsh, acrid flavor, and can make the entire vaping experience unpleasant.
2. Common Causes of the Burnt Vape Taste
Several factors can contribute to the dreaded burnt taste:
-
Insufficient E-Liquid Supply: One of the most common causes of a burnt taste is a lack of e-liquid reaching the coil. The wick inside the coil needs to stay saturated with e-liquid to produce vapor properly. If the wick is too dry, the coil can burn it, creating a harsh burnt flavor.
- Why It Happens: This can occur if you’re using the vape for an extended period without allowing the coil to soak up enough juice or if the e-liquid level in the tank gets too low.
-
Too High Wattage/Temperature: Many vapers enjoy adjusting the wattage or temperature of their device for a stronger hit. However, setting the wattage too high can cause the coil to overheat and burn the e-liquid, especially if the coil isn’t designed to handle such high temperatures.
- Why It Happens: If you set the wattage higher than the coil’s recommended range, the coil may burn the wick or liquid faster than it can vaporize, leading to the burnt taste.
-
Old or Worn-out Coils: Coils degrade over time, especially if they have been used for an extended period. As they accumulate gunk from the e-liquid (especially sweet or sugary liquids), they can lose their efficiency, leading to uneven heating and the risk of burning the wick.
- Why It Happens: A worn-out coil may no longer heat the e-liquid evenly, causing hotspots or burning the liquid, resulting in a burnt flavor.
-
Sweeteners in E-Liquid: Many e-liquids contain sweeteners, which can contribute to the buildup of gunk on the coil over time. These residues can cause the coil to burn at a lower temperature, producing a burnt taste.
- Why It Happens: Sugars and sweeteners can caramelize and burn, creating a charred taste when the coil gets too hot.
-
Chain Vaping (Frequent Puffing): Continuously vaping in quick succession without giving the coil enough time to cool down can result in a dry hit. This happens when the wick doesn’t have time to re-saturate with e-liquid between puffs, leading to burning.
- Why It Happens: Chain vaping places stress on the wick and coil, which may not be able to supply enough e-liquid to keep up with the demand, causing the coil to overheat and burn.
-
Airflow Issues: Many vapes rely on airflow to ensure that the liquid is heated and vaporized effectively. If airflow is restricted, the e-liquid may not vaporize properly, leading to a burnt taste.
- Why It Happens: A closed or restricted airflow may prevent the wick from properly absorbing e-liquid, leading to overheating of the coil.
3. Preventing the Burnt Taste
To avoid encountering a burnt vape taste, consider these practical tips:
- Prime Your Coil: Always prime your coil before using it. This involves applying a few drops of e-liquid directly onto the coil and allowing it to sit for a few minutes to saturate the wick. This ensures that the coil starts with enough e-liquid to prevent it from burning.
- Adjust Wattage Carefully: Pay attention to the recommended wattage range for your coil and avoid setting it too high. Starting with lower wattage settings and gradually increasing them will help prevent overheating and burning.
- Change Coils Regularly: Coils don’t last forever. Replace your coil when you start noticing a drop in flavor quality or when you experience frequent burnt hits. Regular coil replacement ensures optimal vaporization without burning the wick.
- Avoid Thick or Sugary Liquids (at High Power): If you're using e-liquids that are high in sweeteners or VG (vegetable glycerin), be aware that these can cause residue buildup. You may want to reduce wattage when using these liquids or clean your coils more frequently.
- Proper E-Liquid Levels: Ensure your tank is always filled with enough e-liquid to keep the wick saturated. If the e-liquid gets too low, it won’t be able to supply the coil, leading to dry hits.
- Give Time Between Puffs: Avoid chain vaping. Allow a few seconds between puffs for the wick to re-saturate with e-liquid, especially if you’re using a high-wattage device or vaping thicker liquids.
- Check Airflow: Ensure that your device’s airflow isn’t blocked. If your airflow is restricted, it could result in poor vaporization and a burnt taste. Cleaning or adjusting airflow settings can help.
4. How to Recover from a Burnt Taste
If you find yourself with a burnt taste, here are a few actions you can take to recover:
- Replace the Coil: If you’ve already tried to avoid the burnt taste, but it persists, it might be time to replace the coil. Once a coil is burnt, there’s no going back.
- Clean the Tank: Residue buildup can affect the flavor and efficiency of your device. Clean the tank, coil, and any other parts of the vape device to remove any lingering gunk.
- Switch to a Different E-Liquid: If the problem is related to the type of e-liquid you're using, consider switching to one with fewer sweeteners or thinner consistency, especially if you’re using high-wattage settings.
5. Conclusion
A burnt vape taste can be one of the most frustrating experiences for vapers, but it’s usually preventable with a little care and attention. By understanding the factors that contribute to burnt hits—such as dry wicks, improper wattage, and old coils—you can take proactive steps to avoid them. Regular maintenance of your vape device, using the right e-liquids, and paying attention to vaping habits can ensure a smoother and more enjoyable experience.
