Every Bourbon lover knows the key role that maturation of the freshly distilled Bourbon in charred oak barrels plays in the generation of the much loved Bourbon aroma and flavour profile. The Charred Oak Aroma in the Bourbon Aroma Kit is a combination of sensorial rich smoky and woody aromas with the trigeminally active aroma molecules produced during the heat intensive charring step. Our trigeminal sense is an independent sensory pathway with nerve endings in our mouth, nose and eyes.Stimulation of this sense gives a sensation of chemical hotness or heat or tingling. It forms part of our protective mechanism in the body that alerts us to potential danger. A slight tingle-inducing element embedded in the sensuous and rich woody aroma note helps define this class of aroma - one that is especially prominent in many Bourbons. See our Bourbon Aroma Kit - for the “charred oak” and 23 other key Bourbon aromas.
