Big vanilla, caramel, molasses, brown sugar and sweetness to the nares. Tried neat. On the palate it is wow delicious to start with similar notes to the nares of vanilla, oak, molasses, cake, green caramel apple, spice. There is the perfect amount of spice to this and wow not st all hot for the proof of 128.0. I’m surprised on how hot it actually isn’t. Never been a huge jack fan until well, this bottle changed my mind. Cheers!
