Lighting cigars: lighter fluid vs. butane
In my reply, I wrote: "True, there is an 'oily' emission from the flame that may affect the flavor of the cigar, but I often wonder how much this really impacts the taste over the entire course of the smoke...You might as well try it once and taste for yourself."
So, being in possession of a Zippo model myself, I decided to take my own advice and give it a whirl. I love this lighter. It's a chrome "Lady Luck" model, which sports a bikini-clad brunette standing in front of five playing cards that comprise a Royal Flush in Spades. I bought it more for fun because I collect kitschy objects, but since I prefer torch lighters, I never used it to light my cigars.
I filled the lighter with Zippo Premium Lighter Fluid. The can states: "Clean Burning/Improved Ignition/Low Odor." When flicked, the lighter does emanate a slight odor, but it's more noticeable in small spaces, like a car.
The main difference was it took much longer to toast the cigar, and perhaps this is where any fumes might enter the shaft and mingle with the filler leaves. However, I lit up several cigars with my Zippo, and frankly, I didn't taste anything funky in the cigar. Plus, I surmised there was "truth in advertising" with regard to this more refined blend of lighter fluid.
For now, I think I'll stick with my torch lighters, mainly because they're just more efficient and hold up better under windy conditions. But as far as lighter fluid vs. butane is concerned, I don't think there's all that much to be concerned about.
