Quite a bit of info in this thread.
The newer formulation in the square glass bottle is much thinner & greener than the original.
The one you must avoid is the one in the all-plastic flask; there are many reports that the juice deteriorated badly due to being housed in plastic.
l have a glass bottle of the original EDT with the black "shoulders"; the top notes have turned slightly, but it's still the dark, seductive scent that l remember.
The old circular bottles are great, too.
