Flavorah's Bourbon is an additive with Oak, char, smoke and bourbon, although it's fairly light. Great for tobaccos and coffees.
Flavorah's Red Burley is a superb concentrate, certainly among the most authentic tobacco flavours I've tried.
This particular custard has wonderful vanilla notes and is one of my favourites. It's much lighter than Capella's which can be an advantage.
Much like Flavorah's plain butterscotch, with a touch of smoked, charred wood with no ash. Excellent for tobacco vapes.
