Fancy a refreshing pint of betaglucanase? Or maybe a thirst-quenching glass of propylene glycol alginate? These chemicals do not sound remotely appealing. But if you have ever had a pint of cheap lager or ale, it is likely that you have sampled both of them.
I don’t understand why alcoholic beverages are exempt from listing their ingredients, although it would damper my enthusiasm to see caramel listed in my scotch (it’s used for colour, I read).
Germans, however, are purists:
Ever since the German Purity Law or Reinheitsgebot of 1516, beers in Germany can only legally be produced using the core ingredients of water, hops, yeast and malted barley or wheat. Forget chemicals; German brewers are not even allowed to add sugar or lesser grains such as maize or rice.
