Since a ml of an average oil weighs about 0.95 grams, about 12 mls of oil weighs about a tola. I would assume that if the oil varies in weight, the actual amount required to make up a tola would also vary.
I'm not saying that's how Amouage measures their fragrances. They've most likely standardized on 12 mls of volume for an internationally available product. But the amount of 12 mls being a tola is an approximation and may account for some confusion.
I'm going to chime in here and agree with noggs on this.
At this point, I'm not prepared to take any sides on this issue but have always been apprehensive about Amouage's attars in general. And since one Basenoter has already confirmed that a full bottle contains 9.5ml instead of 12ml, there's obviously some cause for concern. That coupled with the batch variations, leaky bottles (yes, there have been many reports of sealed bottles not having been closed and packaged securely to prevent possible leakage - think about the amount of oxidation caused before they're even unsealed) and their sudden withdrawal from Europe, suggests that there could be some truth in this.
I don't think we can firmly conclude anything until someone else has the balls to measure the exact volume of a standard empty Amouage attar bottle. As for the naysayers, you can live in denial as much as you like but, in the perfume industry, nothing surprises me any more with these houses - highly revered or not.
