From what I've read, the reformulation occurred at least a couple years ago, if not a few years ago. I love Fahrenheit, and the bottle I have has a cheap plastic cap and does say "eau de toilette" under the word "Fahrenheit" (the new caps are metal, I think). I bought it from a grocery store ($20!) and it had been sitting on the shelf for quite a while, but I don't know exactly how long. The box it came in was the older two-tone red and blue box, whereas the new box is all red. Basically what I'm saying is I don't know whether the bottle I have is pre-reformulation or not, but it does last a long time and it's strong as hell.
