The determination of the modification of malt.

It is necessary to use EBC Methods 1.1 and 4.5.1

The determination of Hot Water Extract of ale, lager and distilling malts using a constant temperature infusion mashing procedure of a coarsely ground sample (0,7 mm). The wort produced by this mashing procedure is used for ancillary analyses, such as the determination of saccharification rate, colour, viscosity of wort, soluble nitrogen content, free amino nitrogen content, fermentability, and pH. Fine/coarse difference may be derived by simultaneously determining the Hot Water Extract of a more finely ground grist (0,2 mm) from a second test portion of the malt sample.

It is necessary to use EBC Methods 1.1 and 4.1

The determination of the percentage of living corns and pregerminated corns in a sample of barley using a rapid staining technique.

It is necessary to use EBC Method 3.1

It is necessary to use EBC Method 3.1

The measurement of the percentage of grains which can be expected to germinate fully if the sample is malted normally at the time of the test.

The determination of the percentage of grains which can be expected to germinate fully if the sample is malted normally at the time of the test.

It is necessary to use EBC Method 3.1

The determination of the percentage of grains which can be expected to germinate fully if the sample is malted normally at the time of the test.

The estimation of germination percentage and germination rate of grains which can be expected to germinate fully if the sample is malted normally at the time of the test.

It is necessary to use EBC Method 1.1, 3.1 and 3.2

The determination of average com weight as a measure for malting quality.

Bühler Miag disc mill, DLFU, setting the mill for fine grinding, coarse grinding, notes on mill settings, cleaning the mill.

Numerous spectrophotometric measurements are employed in brewing. To obtain reliable results, it is necessary to take certain precautions. The method can be applied to the care of optical glass and silica cells, checking the wavelength and precision of the spectrophotometer.

The instrument manufacturer’s instructions must be read carefully and any safety procedures given must be adhered to strictly.
