    I found this: http://pharmacopeia.cn/v29240/usp29nf24s0_c1191.html

    which suggests that in humid conditions aspirin (acetylsalicylic acid, an ester) can hydrolyse to acetic acid (active ingredient in vinegar) plus salicylic acid (o-hydroxybenzoic acid). I can't find anything on what salicylic acid tastes like but it is said to be odourless. So maybe that is not the explanation - unless somehow the plastic packaging is being affected and this is releasing something.

    Does a tablet fresh from the packet look or smell odd? Is the packaging normal colour and pliability?

    I doubt the aspirin is the bad one. The tablet is a package of several compounds. Such as press release agents , fillers , cellulosic compounds, some coating for taste, and others.

    Fair point. Any idea which of these might be unstable on long-term storage?
