What are these spots on my cigars? Find out now
Mar 14, 2026
It’s completely normal to feel a bit uneasy when you spot a weird mark on a premium cigar. While your first instinct might be "mould!", most discolouration is actually just a byproduct of the growing or curing process.
Here is a simplified guide to what those stains really mean:
Green Stains (Chlorophyll)
These are often mistaken for mould, but they are usually just leftover chlorophyll.
The Cause: The tobacco was dried too quickly (high heat, low humidity), preventing the green pigment from breaking down.
The Verdict: Safe to smoke. It won't affect the flavour or quality.
Sun Spots (Light Brown/Tan)
These look like small, round, or oval "freckles" on the wrapper.
The Cause: A "magnifying glass" effect. If a leaf above has a hole (from insects or hail), concentrated sunlight hits the leaf below, creating a sun-bleached spot.
The Verdict: Purely cosmetic. They have zero impact on the taste or burn.
White Stains (Fungus or "Sesame Seeds")
There are two main types of white marks:
Large & Blurry: Caused by "blue mould" during the plant's growth. Once the leaf is fermented and aged, it is harmless and won't affect the taste.
Small (Sesame Seed size): Caused by the Cercospora fungus while the plant was in the field. It eats the chlorophyll, leaving a tiny white spot.
The Verdict: Safe to smoke. Neither type impacts the integrity or flavour of the cigar.

Black Stains (Excess Sugar)
Dark patches usually point to a humidity issue during the drying stage.
The Cause: High humidity prevented the natural sugars in the leaf from breaking down completely.
The Verdict: Smokable, but potentially unpleasant. It may feel "too fresh" and can cause a scratchy sensation in your throat.
Yellow Stains (Wrapper Fault)
Yellowing is a sign that the tobacco didn't have enough moisture while drying.
The Cause: Insufficient humidity during the curing process.
The Verdict: Low quality. These leaves are generally considered defective and shouldn't make it past quality control, though they do occasionally slip through.
