With that said, if I were indoors and able to light it quickly, I'm not sure I would have tasted it nearly as much. Also, once it's really going, you probably won't taste it anyway.
My understanding is that Bic lighters use butane just like torch lighters. It's Zippos or other lighters that use a wick rather than a jet that use naphtha fuels that impart a different flavor.
