Similarity is based on note and accord overlap, not molecular analysis.
The main accords of Sweet William are warm spicy and yellow floral. It opens with White Pepper and Cardamom, reveals Ylang-Ylang and Tobacco Blossom at its heart, and dries down to Tuscan Iris and Vanilla Absolute. It lasts long and projects strongly; people reach for it in spring and autumn, mostly by day.
