Roger and I are in the UK, not the US... But I'm hearing reports of 'Monster energy drinks' being available in 710ml cans (just like the 'Rockstar') in the UK. Not seen any myself, but I shall keep looking.
(I'm Kevin, BTW, like Kevin 'Bloody' Wilson. Only not quite as rude...)
Interestingly, the 710ml (24oz) can is to be found on the North American version of Rexam's website, but not the European; an issue of US measures (oz) vs European measures (ml), I guess.
It does make you wonder where the cans are made and filled. Surely, they're not filling these things in the US and shipping filled cans to Europe? Since they're both Rexam cans, you might expect that European and US branches of Rexam would be able to supply and can design to customers in their regions, not just the 'local version', and use local filling plants. On the other hand, I recall that 'premium' bottled water, such as Perrier, _is_ shipped to the US. Transporting bottled water across the world? We've gone mad...
> My only concern is the BPA, etc. chemicals on the inside plastic lining that is not meant for heated beverages. Any thoughts or beta?
Well, that's a possible issue, of course, if you can get information on exactly what polymer is used to line the cans; 'epoxy-phenolic' is a term I've seen used. I'd hope that the exact composition must have been declared to the FDA (or similar bodies), and some consideration of these issues must have been made. Whether they considered the use at temperature, I'm not sure, but, as with all chemical reactions, it's a matter of time and temperature; see Arrhenius equation. Any leeching of BPA (or similar) is also likely to follow this relationship. A long shelf life at room temperature or a sun-baked warehouse, or a short cooking time at high temperature? Do we know the activation energy? Does the coating break down at around 100C? Who knows?
Plenty of people seem to use drinks cans as water-heating pots; that doesn't make it safe, of course. We're surrounded by chemicals we ingest knowingly or otherwise. In the end, it's a personal decision; how many people are killed in car crashes every year, and how many die from the effects of BPA? Do you want to stop using your car? Do you want to stop ingesting BPA? Which risks do you consider unacceptable? We're all going to die of something. Even if that something is stress brought on by worrying about what may be miniscule risks... ;-)
