Indeed, we're talking about FDA-approved Poly Ethylene Terphthalate (PET) here, not the nasty-tasting Poly Propylene (PP) that was used for all those horrible bicycle water bottles that made the water taste foul in an hour or two (funny how PP used for yoghurt cups and condiment bottles doesn't taint the product but the water bottles inflicted on children did...) Likewise, the High Density Poly Ethylene (HDPE) buckets used elsewhere for home-brewing is quite safe as the Poly Ethylenes are rather inert. BTW the plastic beer bottles are a PET Polyamide laminate that provides a better barrier to keep Oxygen out and carbonation in - if you are making beer, don't use plain PET bottles instead of proper beer bottles if you want any shelf-life.
