    This is an interesting read:

    https://www.thequint.com/health-fit...pet-bottles-coca-cola-7up-sprite-mountain-dew

    While skewed towards drink consumption, it draws parallels with our use of bottles - particularly speed heat induced steeping methods.

    Interesting is the statement:
    "The tests recovered traces of heavy metals antimony, lead, chromium, cadmium and compound DEHP or Di(2-ethylhexyl). The tests also found that the extent of leaching also increased with a rise in the room temperature."

    Thoughts?

    Not a positive find, :hmmm: got me thinking maybe it will be best to buy glass bottles

    i dont speed steep any more as per say but after mixing i do give them a hot water bath to help mix them, it cant be good heating the bottles then shaking the hell out of them who knows what has hoped a ride on a flavor molecule

    this has definitely made me think twice befor heating juice in the bottles now thanks for that rupert :thumbup: grate bit of info

    Cheers Wanda.

    I think that part of the issue here may be that the plastic production (in asia in this case) is sub par and has allowed heavy metals etc to get into the bottle structure.
    However, given that most of the bottles we use are made in asia, we are likely to encounter the same issues.

    I would avoid heat steeping if its not in glass (in fact, I just don't do it, but thats mainly because I like slow and steady ;) )

    It is another reason I have started sourcing my plastic bottles in HDPE and from an Aussie manufacturer.

    Yeah I'm in the process of changing to glass as well, any elimination of risk is a good thing.
