Decomposing the molecular complexity of brewing

ARTICLE OPEN Decomposing the molecular complexity of brewing Stefan A. Pieczonka 1,2 , Marianna Lucio2 , Michael Rychlik 1 and Philippe Schmitt-Kopplin 1,2 ✉ The compositional space of a set of 120 diverse beer samples was profiled by rapid flow-injection analysis (FIA) Fourier transform ion cyclotron mass spectrometry (FTICR-MS). By the unrivaled mass resolution, it was possible to uncover and assign compositional information to thousands of yet unknown metabolites in the beer matrix. The...
