Cigar Plume vs. Mold: What It Is and How to Identify the Difference

What Is Cigar Plume?

Cigar plume, also known as bloom, is a natural occurrence on well-aged cigars. It appears as a white dusty powder on the wrapper of a cigar and is a sign of proper aging. Cigar lovers often regard plume as a positive indicator that a cigar has been properly cared for and is developing a richer taste over time.

What Causes Cigar Plume?

Plume forms when the oils in the wrapper of a premium cigar rise to the surface over time. This happens when a cigar is stored in ideal humidity levels, allowing the tobacco to age gracefully. A cigar with plume is easily brushed clean with a small amount of effort, leaving no residue behind.

How to Identify Plume

To identify plume, look for a white dust or white dusty powder evenly distributed across the cigar. It should be dry, odorless, and easily brushed off with a soft cloth or brush. Plume does not have a musty odor or any stains, making it harmless and even desirable for cigar enthusiasts.

What Is Cigar Mold?

Unlike plume, cigar mold is a fungus caused by excess moist conditions in a humidor. Mold spores thrive in high humidity levels, leading to moldy cigars that can ruin an entire cigar collection if left unchecked.

How to Identify Moldy Cigars

Mold appears as blue, green, or white growth on the surface of a cigar. Unlike plume, mold spreads and can penetrate the wrapper, affecting the taste and smell of the cigar. A musty odor is often a clear sign of mold contamination, making it unsafe to smoke.

Key Differences Between Plume and Mold

  • Plume is a white dusty powder that forms due to aging; mold is a fungus caused by excessive humidity.
  • Plume is harmless and can be brushed away; mold spreads and can ruin a cigar.
  • Moldy cigars often have a musty odor; plume is odorless.
  • Mold spores can stain the cigar and spread to other cigars in your humidor.
  • Plume enhances the aging process, while mold can completely ruin a cigar.

How to Prevent Mold in Your Humidor

To avoid moldy cigars, follow these humidity control tips:

  1. Maintain humidity levels between 65-72%.
  2. Use distilled water instead of tap water to refill your humidification device.
  3. Regularly check your hygrometer to ensure proper air circulation.
  4. Avoid storing cigars in areas with poor airflow or excess moisture.
  5. Keep an eye on oily wrappers, as excess oils combined with high humidity can encourage mold growth.
  6. Consider using a humidity control pack to keep levels stable.
  7. Rotate cigars periodically to ensure even exposure to humidity.

What to Do If You Find Mold in Your Humidor

If you suspect mold, take these steps:

  • Isolate the moldy cigars to prevent it from spreading to your precious cigars.
  • Wipe the inside of your humidor with a cloth dampened with isopropyl alcohol.
  • Discard moldy cigars that show signs of deep growth inside the wrapper.
  • Monitor your humidity levels to prevent future issues.
  • If your humidor is severely contaminated, consider replacing it entirely.
  • Ensure your humidor is placed in an environment with consistent temperature and air circulation.

Is It Safe to Smoke a Cigar with Plume?

Yes. Plume does not affect the taste or texture of a well-aged cigar. Simply brush it off before lighting and enjoy your stogie as usual.

When Should You Toss a Moldy Cigar?

If a cigar has deep green, blue, or fuzzy growth, it’s best to toss it. Smoking a moldy cigar can negatively impact your health and enjoyment. Unlike plume, mold can penetrate the wrapper and affect the internal tobacco, making it unsafe.

Examples of Plume vs. Mold

  • Example of plume: A well-aged maduro cigar with a fine white dust that gently wipes away.
  • Example of mold: A Connecticut wrapper cigar with blue stains and a musty odor that does not disappear when brushed.

Aging Cigars the Right Way

To achieve a proper aging process, store cigars in a stable humidity-controlled humidor. This ensures that the oils develop properly without causing mold. The aging process enhances the taste and texture of cigars, giving cigar enthusiasts a smoother smoke.

Can Plume Appear on All Cigars?

Plume is more common on premium cigars with oily wrappers. Over time, these oils rise to the surface, forming the characteristic white dusty powder. If you regularly age cigars, you may notice plume appearing after several months to a year.

The Role of a Humidor in Cigar Aging

Your own humidor plays a crucial role in the aging process. A properly cared-for humidor ensures cigars develop complexity while avoiding worst-case scenarios like mold. Proper humidity control, using a hygrometer, and ensuring adequate airflow can make all the difference in maintaining a perfect cigar collection.

Additional Tips for Proper Cigar Storage

  • Rotate your cigars occasionally to ensure even aging.
  • Keep your humidor in a cool, dark place to prevent fluctuations in temperature.
  • If you are unsure whether you are dealing with plume or mold, try wiping it with a clean brush.
  • Avoid overfilling your humidor, as airflow is essential for maintaining cigar quality.
  • Use Spanish cedar shelves or dividers to help regulate moisture.
  • Store cigars in their original boxes for added humidity stability.

Final Thoughts: Plume vs. Mold

Understanding the difference between plume and mold helps cigar enthusiasts maintain a pristine cigar collection. While plume is a natural and harmless sign of aging, mold spores can ruin your cigars if left unchecked. With proper humidity control and regular maintenance of your humidor, you can enjoy aged cigars at their peak flavor without worry. Whether you’re a seasoned aficionado or just starting your cigar journey, knowing how to care for your cigars ensures that every smoke is a perfect one.
