title_body: Impact of bottling in plastic on beer taste
upvoted_answer: Provided all the bottling equipment was properly sanitised (which you'd hope was the case for commercial beer), you shouldn't notice any impact on the taste of the beer.
  
  That said, plastic bottles do not provide as good a seal as a crown sealed glass bottle.  If you store the beer for long enough (say six months to a year), a plastic bottle will have lost some of its carbonation.  If you stick to the "drink by" date on commercial beer though, this shouldn't be a problem.
