The preferred method for extinguishing a cigar is to allow it to rest in an ashtray and naturally extinguish itself. Unlike cigarettes, cigars should not be stubbed out.
Stubbing out a cigar can lead to undesirable consequences, primarily a foul smell caused by the release of oils and tars accumulated during the burning process. This action can result in a lingering, stale odor that detracts from the enjoyment of the smoking experience.
Since cigars only burn when actively puffed, simply letting the cigar rest in the ashtray will prompt it to extinguish relatively quickly. However, if time is of the essence and you wish to ensure complete extinguishment, you can immerse the cigar in a non-alcoholic liquid. Although effective, this method is considered less refined and may compromise the cigar’s integrity.
