A humidor is a specially designed container used to store cigars, tobacco, or other products that require controlled humidity. It maintains a consistent level of moisture, typically between 65% and 75%, to preserve the quality and flavor of the tobacco. Humidors can be made from various materials, including wood, glass, or plastic, and often feature a hygrometer to measure humidity levels. The interior of a humidor is usually lined with Spanish cedar, which helps regulate moisture and adds a pleasant aroma. Properly maintaining a humidor is essential for cigar enthusiasts, as it prevents the tobacco from drying out or becoming too moist, which can affect the smoking experience.
