CRT Humidor Management & Product Storage 3

Question 1

A tobacconist notices the digital hygrometer reads 68% RH but a salt-test calibration shows it is reading 4% high. What is the actual humidity?

Accepted Answer

64% RH

Answer

If the hygrometer reads 4% higher than actual, subtract 4% from the displayed reading: 68% − 4% = 64% actual RH.

Question 2

Which type of humidification device releases humidity most passively and requires the least maintenance in a retail walk-in humidor?

Accepted Answer

Passive gel crystal humidifier

Answer

Passive gel crystal humidifiers slowly release moisture without fans or electronics, requiring only periodic recharging with distilled water.

Question 3

What does 'plume' (also called bloom) on a cigar indicate when observed in a properly maintained humidor?

Accepted Answer

Natural crystallization of tobacco oils—a positive sign of proper aging

Answer

Plume is a fine white crystalline powder formed by the natural oils of aging tobacco and is considered a mark of quality, not a defect.

Question 4

Why is distilled water preferred over tap water when refilling humidor humidification devices?

Accepted Answer

Tap water minerals clog humidification media and promote bacterial growth

Answer

Minerals and chlorine in tap water deposit on humidification media, reducing effectiveness and encouraging microbial growth.

Question 5

A retail humidor experiences a sudden drop to 55% RH due to a failed humidifier. What is the recommended first step?

Accepted Answer

Place a calibrated humidifier back in service and monitor gradual recovery

Answer

Gradual humidity recovery prevents cigars from swelling too quickly, which can crack wrappers; immediate over-correction causes damage.
