Tommy: I have used FA. The black fire I would suggest 1-2 drops per 30 ml. The cuban supreme start out at 1%. EM is good to add to these type of
tobacco flavorings. (My own opinion.) Vape wizard or a few drops of vinegar to tone down the grassy hay type notes also works well. I always had to add a fruit to get the FA flavors to taste halfway decent. I have some oak-wood (FA) that I never even tried.

I suppose I still should try to make the apple-wood I wanted to make.
I tried all the so called good recipes out there for black n mild...LOL they sucked. I did come up with a maceration that came close to it. I made my own essence from a real natural black n mild cigar. LOL I tried it when I made it. I haven't touched it since....I smelled it last night and I am going to blend some this week.
