Hop extract intended for use in beer brewing or elsewhere in the food industry
Ensure prior to performing any analysis that the sample of hop extract is representative, i.e., that the sample is taken from a container of thoroughly homogenized material.
Determination/calculation of original gravity, alcohol and real extract content after distillation of beer, beer-based beverages or beverages.
Beer, beer-based beverages, beverages
After distillation of the sample, the original gravity, alcohol and real extract content of the beer in beer-based beverages or other beverages can be determined from the densities of the distillate and residue.
Determination of the original gravity, alcohol and extract content in beer or beer-based beverages using a thermoanalytical method
wort, beer, beer-based beverages
Rather than utilizing the classic method for analyzing beer by means of density measurement and/or alcohol determination, this device employs thermoanalytical analysis techniques. With two thermoanalytical measuring cells, the beer sample is heated to 40 °C and 65 °C, and the specific heat capacity is determined. Algorithms are used to assign the results to the concentration of the various ingredients. In this way, alcohol content, apparent and real extract, and original gravity are calculated.

The refraction of a light beam as it passes from an optically less dense (sample liquid) to an optically denser medium (prism) is a function of concentration (alcohol/extract), temperature and wavelength. The density of the test liquid is a function of the concentrations of alcohol and extract content. Therefore, from the refractive index (or alternatively the refractive index nD20 and the density or the SGA20/20, the real extract), the alcohol and original gravity can be determined from nomograms or using regression equations.
Isomerized hop extract intended for use in beer brewing or elsewhere in the food industry
A representative sample of the hop extract is necessary for the analysis, i.e., the sample should be taken from a completely homogenized container.
This test method provides a means for evaluating any possible influence originating from the spray-coated lining of a sealed can on the beverage packaged within.
Beverage cans which are used in the brewing and food production industries
The inner lining of the can and the lid should not influence the odor/aroma or flavor of the product in any way. For this reason, the inner lining must conform to the regulations governing foods in the European Union and to those of the respective member states pursuant to their valid constitutions. Furthermore, the provisions drawn up by the BGVV Commission on Plastics in Germany (Bundesinstitut für gesundheitlichen Verbraucherschutz und Veterinärmedizin) must also be taken into consideration.
The safest approach is to perform a comparative taste test with mineral water or beer from the same batch that has been treated in an identical manner in a can (sample) and in a bottle (reference).
