Why Your Cigar Burns Uneven

Updated 2026-10-21 · by Eric

Every burn guide lists the same suspects: humidity, wind, a sloppy light, the way the cigar was rolled. After 49 cigar reviews, nearly all from the same storage and most of them on the back deck, my notes keep pointing at the last one. The crooked burns on this site keep tracing back to the factory... and what one costs a cigar depends on whether it fixes itself.

The case: the Filthy Viking

The Filthy Viking Toro is the cleanest example I have, because it was good right up until it wasn't. A year at 69% in my storage, an afternoon on the back deck, and for two full thirds the burn never saw a lighter. It went a little wonky early, I flipped the slow side down, and it fixed itself almost completely. I don't like burning good tobacco off with a lighter chasing a razor-sharp line, so I didn't.

Near the end of the second third the smoke thinned and the ash split personalities: stacked like dimes on one side, flaky on the other, the side where the burn wasn't keeping up. Rotating stopped working. The first touch-up, going into the final third, paid off immediately... the bitterness backed off and the sweetness came forward. With about half an inch to go one side was a quarter inch behind, and I touched it up again. That side never did burn right, even freshly touched up. Same storage, same deck, same smoker as the first two thirds. The only thing that changed was the stretch of cigar, which is why the review calls it a construction issue in that last inch.

That's the shape of most uneven burns in my notes: a cigar that behaves until it reaches a part the roller built differently.

What happens at the factory

A cigar isn't one material. A buncher gathers filler leaves from different primings into a bunch, rolls it in the binder, and presses it in a mold; a roller stretches the wrapper around it (how a cigar is made). Those leaves don't burn at the same speed. Ligero, the thick top-of-the-plant leaf, burns slowest, which is why blenders bury it in the center. The burn line stays even only when the slow leaf sits in the middle and everything around it is packed and wrapped evenly. Move the ligero toward one side, pack one corner looser, wrap one side tighter, and that side burns at its own speed for as long as the flaw runs.

My reviews keep finding exactly those flaws, usually when the ash comes off and the foot shows what's inside:

• Ashton VSG Torpedo: ligero slightly off center toward the side that kept burning slow, and what looked like a tighter wrap on that side. Four touch-ups.
• La Historia Doña Elena: the ligero clearly to one side, that side slow, and the other side burning quicker with a hole running through it.
• Crux Epicure Habano: a small dot in the wrapper that made one side run fast early on, plus an off-center point in the middle.
• Añejo No. 77 Shark: one corner packed slightly looser than the rest, and a wonky first quarter inch.
• Perdomo 30th Anniversary Maduro: a crack in the binder that showed up during a touch-up, and a foot that was a little hollow when it went out.
• Room101 JT10: a spot near the foot band, a thicker vein or looser section of wrapper, that just didn't want to burn.

What isn't the factory

Humidity, on my shelf, is close to a constant. Nearly every cigar I've reviewed came out of storage at 69%. Near-identical storage going in, and the burns still run from razor sharp to a dozen touch-ups. That doesn't prove humidity doesn't matter. It means my reviews can't isolate it, which is why the humidity test running now counts touch-ups at five levels from 58% to 72%.

Wind is rare in my notes. At least fourteen setup lines report no wind or no breeze. When I did suspect moving air, it wasn't the whole story. The Diesel Whiskey Row watched its early waviness ease when the breeze died, then had one side run a quarter inch long at the end with basically no breeze to blame. The AJ Fernandez Gobernador review wondered about the deck fans I'd turned on for a bit, but that burn ran a little wavy pretty much all night.

Some of it is handling, mine included. The relights after I stepped inside or walked away I don't count against the cigar. The Liga Privada No. 9 went thin and went out on me, and I traced that to a pinch in the shop, not the factory. And sometimes the light is mine: the Flor de las Antillas burned wonky right at the start, I gave it the benefit of the doubt as a bad light, and the touch-up held... for a while. By halfway through the second third I called it officially: not my lighting technique.

That's the test I keep running. Touch it up once. If it holds, it was probably the light. If the same side keeps falling behind, it's the cigar. The step-by-step version lives at fixing a wavy or crooked burn, and the vocabulary at the burn issues glossary.

How burn counts in a verdict

I judge the whole cigar, and that includes ninety minutes of either enjoying it or managing it.

A burn that fixes itself costs nothing, and earns nothing. Seven cigars never needed a touch-up to fix the line, beyond the Hemingway's tapered tip; rotation handled it. Their verdicts run from Hand-Me-One (2/4) on the Hemingway Short Story to Box Buy (4/4) on the Foundation Tabernacle and the Padrón Family Reserve No. 45. A good burn doesn't buy a tier.

A couple of touch-ups late is a footnote. The Filthy Viking landed a Five-Pack (3/4) on price, not burn; the burn gets one line under "best for": expect a couple of touch-ups at the end. None of the six Box Buys here needed more than three touch-ups, and two needed none.

Four or more is a deduction. Ten reviews counted four or more touch-ups, or lost count. None of them earned a Box Buy. Three landed Not Even Free, four Hand-Me-One, and the three that made Five-Pack, the Ashton VSG, the Oliva Serie V Toro, and the Room101 JT10, all name the burn among the reasons they stopped short of a box. The JT10 had box-worthy flavor, and five touch-ups on a $12 stick still held it to a Five-Pack.

Babysitting all night can be the verdict. The Perdomo 30th Anniversary Maduro barely held a Hand-Me-One (2/4), and the review says the burn is what put it there. The Flor de las Antillas review pins its Hand-Me-One on the burn too.

Part of why I count it this hard: a crooked burn is often a flavor problem too, and on the VSG some of what I didn't love was the burn talking. The Crux Epicure Habano review put the line where I keep putting it: at $14 a stick I'll pay for a cigar I have to manage a little. I won't buy twenty of them.

And it's always one cigar, one night. The Romeo y Julieta Habana Reserve needed better than a dozen touch-ups, and the review says right there that it could be that one stick and not the blend. It still gets reported as the cigar I smoked, because it's the one you might buy.

The short version

Wavy is normal, and rotation handles most of it. Crooked once is usually a fix. The same side dying all night is the roller, and it goes in the verdict, because you're not just buying flavor... you're buying the ninety minutes it comes in.
