I just had a splendid success with TPA
tobacco Absolute. TA is very much a "less is more" sort of a thing.
I started with concentrated pure
tobacco Absolute. Pure TA needs a warm water bath before you can handle it easily. I made a 10% solution of PG and ethyl maltol crystals (1/4 teaspoon in 10 mL). To this I added 2 drops of pure TA, and let it sit for 3-4 days.
Then I made a 15 mL batch of my preferred base liquid, and added:
1% (5 drops or 0.2 mL) of TA/PG solution
4% (0.6 mL) TPA French Vanilla
2% (0.3 mL) TPA Dulce de Leche
This makes a rich, cigarette-like flavor that is faintly sweet with just a hint of vanilla.
