For me, there are two kinds of cinnamon. "Fire" and "Christmas."

Fire is just hot. Cinnamon Mentos, Jolly Rancher Fire Stix.

Christmas I feel is "Apple cinnamon" but apple isn't always a part of it. It's a milder Cinnamon and tastes more like the smelkl of cinnamon other than just hot. That's the smell of Christmas for me.
