The Application Of Metabolomics To Ascertain The Significance Of Prolonged Maturation In The Production Of Lager-Style Beers

NMR-focused metabolomic analysis has been employed to ascertain the extent to which a diversity of non-volatile substances change in level during maturation and storage on a pilot and commercial scale. No substantive changes were observed, leading to the conclusion that, once materials such as vicinal diketones and acetaldehyde have been dealt with, there is no merit in the prolonged storage of beer.
