My purchased at your PET bottles with the gray (used print until 2015) who before the new filling; and according to the carbon dioxide filling a penetrating Plastic smell of drinking automatically triggers in the nose. A white and a gray bottle from the same delivery with (the EXP 10.2014) on the other hand are Ok and totally odorless. I have all the bottles reglmäßig in use. Despite prescribed cleaning and maintenance, the rubber seals and plastic verscgraubungen of 2 gray PET bottles are toxic and useless! I'd be happy if you give me for free, which would replace Gray set of three against a set of three white odorless. Sincerely Wilfried Drüke
