Answers.Text: Yeah... So sorry. My brain TOTALLY got stuck in bourbon aging mode. Where, the age comes from time in cask so taking it out and putting it in a bottle stops the aging process. So sorry.

Comments.Text: @AndrewCheong I disagree. Opened containers have a number of different variables in play, compared to closed containers. For closed containers, you're mostly worried about chemical reactions internal to the product - this is the point of the "best by" date referred to in the proposed duplicate. With opened containers, you have to worry about reactions with the air and any contaminants it may carry. Also, as "open" generally implies "partially used", you may have additional bacterial contaminants to be concerned with if the container was drank from directly.

Comments.Text: @user162 - You're right. Not sure what I was thinking. I probably somehow missed "(opened)" in the title, and read MD-Tech's comment about it being ambiguous.

  ### Answer by username_7 on 2015-03-24. Score: 2
  
  Your question says they were opened? I'm going to venture probably not. You tagged this 3.2-beer, does that mean these are low alcohol session beers somewhere around 3.2% ABV?
  
  If the beers aren't moldy, best case scenario is you now have two bottles of home made malt vinegar. Make a balsamic, have some steaks with side salads.
  
  If they were closed or sealed in any way, they're probably fine, though depending on the style they probably won't taste great. Low alcohol and hoppy beers don't age gracefully. Higher alcohol or darker beers often do better with some time on them. But either way you have to keep them away from air, namely other microbes and oxygen or else things go downhill real fast.
