8.10.1 - Free Amino Nitrogen in Wort by Spectrophotometry - Manual Method (IM)

The determination of the free amino nitrogen content of wort using colorimetry with ninhydrin. The method gives an estimate of amino acids, ammonia and, in addition, the terminal α-amino nitrogen groups of peptides and proteins. Proline is partially estimated at the wavelength used. The method is not specific for α-amino nitrogen since γ-butyric acid which is present in wort gives a colour reaction with ninhydrin.

8.10.2 - Free Amino Nitrogen in Wort by Segmented Flow Analysis

The determination of the free amino nitrogen content of wort using colorimetry with ninhydrin. The method gives an estimate of amino acids, ammonia and, in addition, the terminal α-amino nitrogen groups of peptides and proteins. Proline is partially estimated at the wavelength used. The method is not specific for α-amino nitrogen since γ-butyric acid which is present in wort gives a colour reaction with ninhydrin.

8.10.3 - Free amino nitrogen in wort by automated discrete analysis (IM)

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.

8.20 - Iso-alpha-acids and alpha-acids in wort by HPLC

This method specifies a high performance liquid chromatographic technique for the simultaneous determination of iso-α-acids (iso) and α-acids (alpha) in wort. It is recommended for wort samples containing α-acids and iso-α-acids. Due to the coelution of iso-α-acids (or α-acids) and reduced iso-α-acids, this method is not recommended for the analysis of wort samples containing reduced iso-α-acids.

9.2.1 - Alcohol in Beer by Distillation

The determination of the alcohol content of beer using a distillation procedure and measurement of specific gravity of the distillate. Alternative procedures may produce accurate results but the distillation procedure is regarded as the reference method for alcohol.

It is necessary to use EBC Method 9.43.1 and 9.46
