At the recent ACS NERM 2013 meeting Adam Dicaprio of Process NMR Associates presented two topics on sour beer analysis by NMR.

“Small Molecule Chemistry of Spontaneously Fermented Coolship Ales” … PDF Technical Poster

“When Beer Goes Sour: An NMR Investigation” … PDF – Oral Presentation

NMR Assignments of interest. 1H qNMR obtained from relative molar ratios established from compaison of maleic acid internal standard with small molecule signals.
