Chemists at the Complutense University of Madrid have developed a method that allows brewers to measure the freshness of beer using a polymer sensor that changes colour upon detecting furfural, a compound that gives aged beer a stale flavour. The sensor can be controlled via a smartphone app also created by the team.
