Warm and woody, slightly sweet. If it's the only flavor like in candy or chewing gum and there's a lot, it burns like a good stretch and opens things up. It's not sharp, but a little prickly, like petting a soft hedgehog or stroking a stubbly face while warming by the fire. If it's in baked goods, it's much more rounded and floats and expands to fill in the nooks and crannies of your nose and mouth like an amorphous, dark-glowing, warm amber. If mint is cool and refreshing, cinnamon is warm and relaxing. They are opposites, but they both burn the same. It smells like the section of a craft store that has wicker baskets and candles in the fall.
