A burnt hit is not a flavor. It is a system failure.
When you taste burnt cotton, you are tasting the result of dry wicking material reaching 230 degrees Celsius or higher. Cotton ignites at roughly 210 degrees. What you are inhaling is not vapor. It is thermal decomposition byproducts. That is not an opinion. That is chemistry.
The most common cause is the simplest: your liquid level dropped below the wicking ports. Most pod systems and tanks have wicking ports positioned 3-5mm from the bottom of the tank. Once the liquid drops below that line, the cotton is pulling air instead of e-liquid. It takes approximately 1.5 seconds of dry fire for the cotton to scorch. After that, the coil is permanently damaged. You can refill the tank. You cannot un-scorch the cotton.
Chain vaping is the second most common cause. A coil needs time to re-saturate between pulls. At 40 watts, a standard vertical coil consumes roughly 0.02ml of liquid per second of fire. The cotton wicks at roughly 0.015ml per second. Do the math: every second of firing creates a 0.005ml deficit. Chain three pulls together and you are dragging dry cotton across hot metal. Wait 20-30 seconds between pulls. Your coil will last 40% longer.
Priming is the fix everyone knows about and most people rush. A new coil needs 5-10 minutes of saturation time. Not 30 seconds. Not "I'll just take a small hit." Five to ten minutes. Put liquid on the exposed cotton ports. Fill the tank. Wait. The difference between a properly primed coil and a rushed one is 3-5 days of coil life. That is not an exaggeration.
When to give up: if you have replaced the coil, primed it properly, waited the full 10 minutes, and the first hit still tastes burnt — your device is the problem, not the coil. The chipset may be outputting incorrect wattage. The 510 connection may have a short. The airflow sensor may be malfunctioning. A new coil in a faulty device will burn just as fast as the old one.
The takeaway: A burnt taste is a signal. The signal says "something is wrong." Fix the root cause, not the coil. Otherwise you will just keep burning coils and wondering why.
