Запах дыма костра. Думаю, а причем здесь клен в описании аромата ?
Ответ с сайта Деметера:
Our version of Bonfire has a decidedly American, point of view.
We remember a less complicated and less regulated time, when we would rake the fallen, dried maple leaves from the lawn into large piles, which our fathers would burn, making the bonfires of our youth.
It is that smell of burning maple leaves that is the heart of our Bonfire cologne-Это запах горящих листьев клена.
