I was reading this thread which seems to indicate very few mainstream breweries package in PET bottles, except for cheap brands, or in locations where glass is a problem.
Is there any real concern with using PET packaging for beer, other than the general consumer perception?
There are nice 500ml amber PET bottles available that I'd love to use, and I've been experimenting with them for a while now. I like the package from an aesthetic point of view. It feels good in the hands, to the point that you forget its a PET bottle. You can easily fill it isobarically and oxygen free.
It's possible to create a PET bottle using combination of oxygen scavenger with an LC2 outer coating (a double liquid coating consisting of polyvinyl alcohol PVA and nano-varnish) that has extremely low oxygen permeability (less than 100 ppb over 6 months). There are other coating methods as well.
There are many advantages to PET bottles, and in some ways they're better than aluminum cans. I think this is the ideal package for craft brewers.
So what's the deal with PET bottles, and why aren't they used by mainstream breweries? In other words, are they used only for cheap beer because that's the general perception, or is there actual science involved?
