Hi, PiperM back as a follow up. To clarify my earlier post,I'v found the two drops of vanilla extract to "neutralize" the fuel flavor.This means make the bad taste that ruins your pipe tobacco flavors mostly unnoticeable,or greatly deminished! I hardly notice the vanilla flavor at all,but do enjoy the flavors of the tobacco more upon lights/relights MUCH more now.Try it,you'll like it!
