Similarity is based on note and accord overlap, not molecular analysis.
Differences come from accords and community votes on longevity and sillage.
The main accords of Dirham Oud are woody and citrus. It opens with Citruses and Bergamot, reveals Sandalwood and Rose at its heart, and dries down to Woodsy Notes and Agarwood (Oud). It lasts a moderate time and projects moderately; people reach for it in autumn and winter, day or night.
