This one is an alternative to PDM Althaïr, just as good as Fragrance World Liquid Brun (I don't have the OG). A wonderful aromatic, spiced, sweet, resinous, nutty, gourmand and delightful scent profile. This is a mass appealing aroma that I will use anytime anywhere, but I know people might be more specific of when to use it. It has great projection and longevity. This is a steal.
