German scientists have found a way to make beer last longer in storage.

According to Andrea Dunkel, a food technician at Technical University of Munich, stored beer eventually becomes unpleasant because of the breakdown of iso-alpha acids, the compound causing its bitterness.

Dunkel and his team discovered that when iso-alpha acids break down, several other compounds are formed which then makes stored beer intolerably bitter. They found this by analyzing samples of beer at different stages of break down for up to 10 years.

They were also able to determine the speed and sequence of break down by recording the process every two weeks for almost two years of observation.

Their conclusion shows that beer turns unpleasant after about four to six months in storage. In addition, the by-products of the break down multiply as beer stays longer in shelves.

As a result of Dunkel’s research, beer brewers can now produce beer that lasts longer, saving them the cost of throwing away old beer. Dunkel proposes that keeping beer cool and altering the ingredients of beer can help beer stay fresh even in storage.
