If Agarwood disappeared I guess I would burn Bakhor and Frankincense. Now if we agree on the premiss that agarwood oil increase in value as it ages, then it is expected to increase in cost over time. The Chinese Exclusive was the first oil I tried from Ensar's Oud. I found to be very powerful with over the top barnyard notes, very unabashed and kind of strident, I likened it to a military marching band, lowd and proud. However, even though I always wanted to get it I never did in due time and now of course I have only myself to blame. Perhaps it was one of the least appreciated oil in the collection then. But now with the diminishing existance of wild Agarwood oil I am sure we will be seeing higher and higher prises on specially marketed wild Oud.
