Today, the European Brewery Convention (EBC) and the American Society of Brewing Chemists (ASBC) are publishing two international methods on Free Amino Nitrogen and β-glucans measurement in wort by automated discrete analysis. The Methods are available on BrewUp (www.brewup.eu) for the EBC and on the ASBC website (www.asbcnet.org).
EBC Method 8.10.3 Free Amino Nitrogen in Wort by Automated Discrete Analysis (IM) – 2021 allows for the determination of the free amino nitrogen content in wort using photometric measurement of OPA (oPhthaldialdehyde) and NAC (N-acetyl cysteine). The method is performed manually or automatically at a 340 nm wavelength at 37 °C temperature.
EBC Method 8.13.3 β-Glucan in Wort by Automated Discrete Analysis (IM) – 2021 allows for the determination of beta-glucan in wort samples.
Both methods have been tested through an International Collaborative Trials involving participants from the ASBC network in the United States and from the EBC network in Europe.
The two Methods available for sale on BrewUp and can be found respectively here (EBC Method 8.10.3 Free Amino Nitrogen in Wort by Automated Discrete Analysis (IM) – 2021) and here (EBC Method 8.13.3 β-Glucan in Wort by Automated Discrete Analysis (IM) – 2021).
The European Brewery Convention and the American Society of Brewing Chemists would like to thank all the experts and laboratories involved in this international collaborative trial as well as members and experts of the EBC Analysis Group, EBC Sub-Committee Beer & Wort and ASBC Technical Committee who participated in the International Collaborative Trial.
