One of the fundamental rules when smoking cigars is that you should never light it with a Zippo or liquid fuel lighter. The reason this rule exists is because people believe that the liquid fuel can be absorbed by the cigar and either change the aroma or ruin the flavour. I believed this rule for quite some time to until recently when I decided to test the theory.
I recently bought my very first Zippo lighter and since then I'm hopped on the proverbial bandwagon. I'm now all about Zippo lighters and love how brilliant they are. I even tried them on cigars and found that the idea that Zippo lighters can ruin cigars is complete nonsense. The fuel that Zippos use has absolutely no impact on cigars at all.
