Query: New bottle/formula tastes plastic-y

I really like Zico in the tetra pak. When I tried the bottled formula, I didn't realize that the formula was any different...I just thought it was a new bottle. My reaction to every sip was that it tasted and smelled very plastic-y. It seemed that sitting in the plastic bottle was imparting a plastic flavor to the drink. I couldn't even finish the drink and immediately wrote a letter to Zico asking for the Tetra Pak back! I then did a little research and realize that this is the new flavor of this formula using a new variety of coconut and from concentrate. I really don't like this new flavor at all. I will not be buying this product in the bottle again.
