Burnt Flavour Despite liquid? Investigating the causes
Sometimes the most frustrating problem occurs when vaping: a sharp, burnt taste.
We delve deep into the subject and examine the most common causes of this problem. From deposits caused by sweet Liquids From incorrect power settings (known as "coil gunk") to your own vaping technique – here you'll learn how to identify, fix, and avoid these problems in the future. This knowledge is key to getting the most out of your vaping experience.
1. The main cause: "Coil gunk" due to sweet e-liquids
One of the most common, but least understood Causes of a burn
The mechanism behind it:
When you vape, the e-liquid is heated by the Mesh Coil The e-liquid vaporizes. While the main components like PG, VG, and nicotine vaporize cleanly, heavier sweetener molecules cannot dissolve completely. Instead, they "bake" onto the hot surface of the coil. Over time, a dark, sticky crust forms. This deposit acts like an insulating layer, preventing the fresh e-liquid from the tank from efficiently cooling the cotton in the coil. The coil overheats in these areas and begins to scorch the cotton—even if it is theoretically saturated with e-liquid. The result is an increasingly burnt taste.
Recognize and avoid:
- Visual inspection: If possible, take a look at the coil inside the pod. Does it look... Cotton wool or the metal mesh Does it look dark, encrusted, or almost black? That's a clear sign of advanced coil gunk.
- Liquid choice: If you are constantly faced with this problem, try switching to less sweet e-liquids. Our [link to relevant page/guide] offers a good guide. Guide to fruit e-liquids for pod systems.

2. Incorrect power setting (watts): A common mistake with variable systems.
Not every pod is designed for every wattage. The complexity and performance of vaping devices are increasing, as the industry association VdeH also points out in its [document/report/etc.]. Market analyses This requires more attention from the user. The electrical resistance of the coil, measured in ohms (Ω), determines the ideal power range.
A common mistake is using a pod at too high a wattage. For example, the
The golden rule:
When using a new coil or pod, always start at the lower end of the manufacturer's recommended power range and gradually work your way up.Modern devices such as the

3. Your vaping technique: The danger of chain vaping
Even with the correct wattage and e-liquid, your personal vaping habits can be the cause. "Chain vaping"—taking very short, consecutive puffs without a break—is a sure way to prematurely ruin a coil.
The mechanism behind it:
After each puff, the cotton in the coil needs to absorb new e-liquid from the tank. This saturation process takes a moment. If you puff again immediately, the cotton won't have time to fully absorb the liquid. It will still be dry in some places when the coil fires again. The dry cotton will burn instantly, resulting in the dreaded "dry hit." This single moment can be enough to cause a serious problem.
Here's how to avoid it:
- Give the pod a break: Wait between the
puffs deliberately wait 15 to 30 seconds. This gives the wicking system enough time to fully re-saturate with liquid and ensures that every puff tastes as fresh as the first.
4. Preparation is everything: The right "priming" of a new pod
One step that is often skipped out of impatience, but is crucial for the longevity of a coil, is "priming." This is especially true for refillable pods. A new, dry pod should never be fired immediately.
Step-by-step instructions for proper priming:
- Fill the pod: Fill the new, refillable pod with your chosen e-liquid.
- Wait: Leave the filled pod upright for at least 5-10 minutes. During this time, the dry cotton inside will slowly absorb the e-liquid.
- Primer Puffs (Optional): Pull the mouthpiece out a few short, gentle tugs, without Pressing the fire button or activating the device at the same time. This negative pressure helps to draw the liquid more quickly into the core of the coil.
Skipping this step risks the coil hitting dry cotton upon first firing. The cotton will burn instantly, rendering the pod unusable from the very first second. Adhering to these usage practices is crucial to achieving the quality ensured by manufacturing and testing standards such as... ISO 20768 is being pursued for aerosol generation.
