That harsh, acrid taste of a burnt hit is a rite of passage for every vaper. It’s unpleasant, ruins your vaping experience, and is a clear sign that something is wrong. If you’re wondering why your vape tastes like a campfire and how to make it stop, you’ve come to the right place. Let’s break down the common causes and their simple solutions.
The Culprit: The Burnt Coil
At the heart of most burnt taste problems is the coil. Inside your vape pod or tank, a coil head contains a heating wire surrounded by wicking material, usually cotton. This cotton soaks up e-liquid, and when you fire the device, the wire heats up, vaporizing the liquid.
A burnt taste occurs when the coil is heated without enough e-liquid. This causes the dry cotton to singe or burn, and that terrible flavor is then carried directly into your lungs. Once cotton is burnt, the damage is permanent and the coil needs to be replaced.
Common Reasons for a Burnt Taste (and How to Fix Them)
1. A Priming Problem (The Most Common Beginner Mistake)
-
The Cause: You installed a brand new coil but didn’t “prime” it before use. The cotton was completely dry, and you instantly burned it on the first fire.
-
The Fix:
-
Prime Your Coil: Before installing a new coil, put a few drops of e-liquid directly onto the cotton you can see through the wicking ports.
-
Fill and Wait: After installing the primed coil and filling your tank, let it sit for at least 5-10 minutes. This allows the cotton to fully saturate from the inside.
-
Start Low: For your first few puffs, take a few sharp, short pulls without firing the device. This helps draw liquid into the coil.
-
2. Low E-Liquid Level
-
The Cause: You’ve been vaping happily, but the e-liquid level in your tank has dropped below the coil’s wicking ports. The cotton can’t absorb any more liquid and starts to burn.
-
The Fix: This is an easy one! Keep your tank topped up. Make it a habit to refill before the e-liquid level falls below a quarter of the tank’s capacity.
3. Chain Vaping
-
The Cause: Taking multiple puffs in quick succession doesn’t give the wick enough time to re-saturate with e-liquid between hits. You’re essentially vaping the cotton faster than it can drink, leading to a dry, burnt hit.
-
The Fix: Slow down. Give your device 15-30 seconds between puffs to allow the coil to cool down and the cotton to absorb more juice. This is especially important with high-VG liquids, which are thicker and wick more slowly.
4. An Old, Gunked-Up Coil
-
The Cause: Over time, sweeteners and flavorings in e-liquid caramelize on the coil wire. This “gunk” insulates the coil, causing it to heat inefficiently and burn the surrounding cotton. You might notice a gradual decline in flavor before it turns outright burnt.
-
The Fix: Replace your coil. Coils are consumable items. Their lifespan varies depending on your e-liquid and vaping habits, but most last between 1 to 2 weeks. If your vape tastes off and it’s been a while, a new coil is the answer.
5. E-Liquid Viscosity (VG/PG Ratio)
-
The Cause: You’re using a high-VG e-liquid (e.g., 70% VG or higher) in a device designed for thinner liquids. VG is thick and has trouble wicking quickly in small pod systems or tanks with tight wicking ports.
-
The Fix: Match your e-liquid to your device.
-
Pod Systems & Starter Kits: Use a 50% VG / 50% PG or 60% VG / 40% PG blend for faster wicking.
-
Sub-Ohm Tanks: Can typically handle high-VG liquids with ease.
-
6. Wattage Too High
-
The Cause: You’re firing your device at a wattage higher than your coil is rated for. The coil heats up too fast and incinerates the e-liquid and cotton.
-
**The Fix: ** Check your coil’s recommended wattage range, which is usually printed on the coil itself or its packaging. Always start at the low end of that range and gradually increase the wattage to your liking.
Troubleshooting Checklist: What to Do Right Now
Follow these steps to diagnose and solve your burnt taste issue:
-
Check the E-Liquid Level: Is the tank low? Refill it.
-
Inspect the Coil:
-
Is it a new coil you just installed? Prime it properly and let it sit.
-
Has the coil been in use for over a week? Replace it with a new one.
-
-
Check Your Wattage: Is your device set within the coil’s recommended range? Lower the wattage.
-
Change Your Habits: Have you been vaping too frequently? Slow down and let the wick saturate.
-
Change Your E-Liquid: If you’re using a very sweet or high-VG liquid in a small device, switch to a less sweet, thinner (higher PG) e-liquid.
The Golden Rule
Once a coil is burnt, the burnt taste will not go away. You can try cleaning it or poking holes in the wick to improve flow, but these are temporary fixes. The only real solution for a burnt coil is replacement.
