Tonka Impériale, launching this month, will be the seventh fragrance in Guerlain's L’Art et la Matière line.
The new scent was developed by Guerlain house perfumer Thierry Wasser. The notes for the gourmand oriental include rosemary, tonka bean, honey, spices, almond, vanilla, woods, tobacco and amber. Sylvaine Delacourte of Guerlain describes it as "between gingerbread and chocolate".
