das ist nicht mein Bier

that's not my problem; that's none of my business

Origin

The origin is not firmly established; usually 'Bier' is taken literally - everyone is responsible only for his own beer (his own affair). Others trace it to regional words (e.g. for 'pear' in the sense of 'matter'). The phrase has been current since the 19th century.
