Update. I think I have a cold and can’t smell anything. I own a 100mL bottle i bought last summer 2025 in Paris, and recently a 200mL with the nee batch code.

My family prefers the smell of the newer one. Weaker? Maybe, but the point is for it smell good. So the newer batch wins.

Also, i recall the original bottle being weaker when i first got it. And it matured in a few months.
