Sorry if this isn't the right forum for this question, but figure'd homebrewers would be the best place to ask about the properties of beer: I bought a growler of Belgian Strong Ale from Greenbush in MI ("1825") on 4th of July. I had one pint but had to leave it behind while I traveled the next day. I'm just getting back to it almost 2 weeks later. It's been tightly capped in a fridge, and still shows carbonation when shaken up. Is it safe to drink still? The original ABV was between 8-9%. Are there general rules on the lifespan of beer in growlers, especially amongst different styles, and with regard to refrigeration? Do those plastic seals they put on caps preserve it longer? Thanks in advance if any of you can offer any help, or point to previous threads involving this topic.
