title_body: Beer in plastic bottles and health aspects
upvoted_answer: Plastic food packaging in general is usually lined with Bisphenol A (aka. BPA), as are some canned goods, which is a rather controversial chemical. It's been linked to cancer, sexual dysfunction, and other ailments. So I try to avoid it whenever possible and buy my food in glass jars. I can only imagine how much BPA is  dissolved into alcoholic beverages which are bottled in plastic or cans, being that alcohol is corrosive. I learned that lesson when I tried cleaning my GameBoy with rubbing alcohol as a kid. So I try to avoid alcohol bottled in plastic and canned alcohol as well.
  
  The thing you have to realize is that plastic isn't really a solid, but a very viscous liquid. Glass is also a liquid, but it's much more viscous than plastic. That's why if you've ever been in a building that's a couple hundred years old, the glass on the windows is thicker at the bottom of the glass panes. Since both are liquids, they're obviously going to get into your drink. However, glass is a natural substance while plastic is not, so I trust it more.
