Four new EBC Methods available

New methods | On 1 July 2021, the European Brewery Convention (EBC) and the American Society of Brewing Chemists (ASBC) published two international methods on Free Amino Nitrogen and β-glucans measurement in wort by automated discrete analysis and two new International Methods in microbiology developed over the past three years by experts on both sides of the Atlantic Ocean.

All Methods are available from Brewup for the EBC and from the ASBC website.

Two new International Methods on FAN and β-glucans measurement in wort

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 (o-Phthaldialdehyde) 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.

Two new methods on Microbiology

EBC Method 3.5.3 Live Yeast Detection with FastOrange® Yeast Medium (IM) from 2021 allows the detection of yeast cells of all species including brewing yeast strains which are alive and have the capability to proliferate.

EBC Method 4.2.7.1 Dekkera (formerly Brettanomyces) Detection with FastOrange® Brett Medium (IM) from 2021 allows for the detection of super-attenuating Dekkera yeasts – formerly Brettanomyces – in brewery samples or within other yeasts on FastOrange® BRETT agar medium.

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.
