8.2.1 - Specific Gravity of Wort using a Pyknometer

The determination of the specific gravity and the defined specific gravity/density derived values of wort in air at 20 °C by weighing a known volume in a pyknometer or gravity bottle. Descriptors: pyknometer, reischauer type, gay-lussac type, gravity bottle.

8.2.2 - Specific Gravity of Wort using a Density Meter

The measurement of the specific gravity and the defined specific gravity/density derived values of a wort at 20 °C using digital density meters of the oscillation type.

it is necessary to use EBC Methods 1.6 and 8.3

8.6.2 - Fermentability, Attenuation Limit of Wort Rapid Fermentation

The determination of the amount of fermentable sugars in the wort using a rapid yeast procedure. This rapid method is given for guideline purposes only. It must be taken into consideration that the rapid method may lead to lower results compared to the reference method (EBC Method 8.6.1).

8.7 - Fermentable Carbohydrates in Wort by HPLC (IM)

The determination of fructose, glucose and sugars with 2 and 3 degrees of polymerization (DP2 and DP3) by high performance liquid chromatography (HPLC). The DP2 peak is primarily maltose, while the DP3 peak is primarily maltotriose. The method cannot distinguish between different disaccharides or between different trisaccharides. Flow rate and column temperature are considered to be sensitive parameters. Deviating from the procedure may alter the results.

8.8 - Bitterness of Wort

The determination of the bitter substances, mainly iso- α-acids, in wort.

It is necessary to use EBC Method 9.8

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 (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.

8.19.1 - Dissolved Oxygen in Wort using Optical Sensors

The determination of dissolved oxygen in wort using optical oxygen sensors. Descriptors: solubility of oxygen in water in equilibrium with air at 1,01325 bar and vapour pressure of water in equilibrium with air, solubility of oxygen.

it is necessary to use EBC Method 9.37.1
