The method describes the conditions under which sensory analysis is to be conducted.
beer, beer-based beverages, non-alcoholic beverages, mineral water
One of the basic prerequisites for properly conducting sensory analysis is training the members of the tasting panel.
As is the case with drinking water, water employed for the production of beer and soft drinks must be neutral in odor and taste.
beer, beer-based beverages, non-alcoholic beverages, mineral water
A qualitative test is performed after shaking the water in a sealed, odor-neutral bottle. Water possessing an odor is measured quantitatively on the basis of a sensory threshold. Water possessing an odor is diluted with odorless water until the odor is barely perceptible (by at least three people). The ratio of the total volume (water with odor + odorless water) to the volume of the mixture containing the water sample is designated as the odor threshold. The taste test should always be performed after evaluating the odor, since the perception of odor can be influenced by flavor.
Barley malt (pilsner malt) and smoked malt intended for use in beer brewing or elsewhere in the food industry
The phenol fraction collected through steam distillation is mixed with 4-amino- 2,3-dimethyl-1-phenyl-3-pyrazolin-5-one (4-aminophenazone) under alkaline conditions and oxidized by potassium hexacyanoferrate(III) to form a pigment (fig. 1), which after extraction with chloroform, can be measured spectrophotometrically.

This method describes the how to determine the odor and flavor of malt through manual examination.
Malt intended for use in the brewing and food production industries
This method is applicable to other malted grains as well.
Malt to be received at the brewery must be free of foreign odors/flavors and other contaminants.
The malt is evaluated by smelling it and by biting the kernels. Steeping the malt kernels in hot water is also helpful.
This method describes how to evaluate the sensory impact of activated charcoal.
Activated charcoal is added to a sample and stored at 50 °C for 24 hours. The sample is then tested against a control sample sensorially.
