Montale Black Aoud by Montale Perfume. Released in 2006, Montale Black Aoud perfume is a long-lasting scent with incredible silage. Its star ingredient is oud, a rare oil formed by agar trees that have a certain mold. Very few trees produce oud, making it one of the most valued ingredients in the world. Some people even refer to the resin as “liquid gold.” Other notes in this sensual, intense fragrance include musk, Indonesian patchouli, mandarin orange, rose and French labdanum.
