Quite often when I want to review a beer it says that the beer is "retired no longer brewed", and the note may be several years old. Yet, on the beer label on the bottle that I am drinking from it says it was bottled last month. Sometimes I make a comment under the update section. I am wondering, what "evidence" is needed for the update to happen? Or is it perhaps better to add a new beer with the same name? I am asking about the latter because the 2013 release may be quite different from the 2017 release.
