cigar taste like butane
What you taste is unburned carbon (carbon monoxide) not butane.
You wont get any carbon taste from a torch lighter. Even a cheapo torch burns the carbon completely, converting it to carbon dioxide which has no odor or taste. The disposable butanes dont burn hot enough to fully combust the carbon.
If your interested in seeing what its like to light up with a cedar match just tear a piece from one of the cedar sheets that come in some boxes and light it, use that to light your smoke. Personally, unless your looking for some kind of added “ambiance” its goofy. But hey if you have a steady source of cedar matches then rock on. Either way, I’d bet you’ll use a torch in the end. It’s just so much easier.
