I bought some cooks Hazelnut and I put five drops in my tobacco mixture (10 ml which were mostly light flavors) I didn't like the red type flavoring from TFA I had added and the Hazelnut either muted it or rounded it off. The Hazelnut it's self had a slight sweet woodsy flavor. Im sure this flavor could be useful. Here are the ingredients. Ingredients: glycerin, natural flavors, caramel color, and water. So the flavors are natural and there's no alcohol I just wish there was no coloring.
