This method describes how to correctly collect a sample of water.
Water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
Collecting samples correctly is a prerequisite for obtaining flawless analytical results. The sample collection method must be adapted to align with the purpose of the analysis method. As a rule, separate samples are taken for chemical and microbiological analyses, since different equipment and containers are required for the collection and treatment of samples.
In principle, sample collection methods are distinguished as follows:
Random samples collected for analysis identify possible contamination or can be collected for purposes of orientation prior to more extensive sampling.
Both intermittent (discontinuous) sample collection (according to certain time intervals, volumes or flow rates) and continuous sampling, which allows for constant monitoring of flowing water for compliance with quality standards, are possible. Samples taken continuously can be mixed to create composite samples and provide mean data.
A series of samples (taken at different depths or over a given area to perform profile tests) are collected for analysis in the process of testing standing water.
This method describes the conditions under which sensory analysis should be carried out.
beer, beer-based beverages, non-alcoholic beverages, mineral water
One of the basic prerequisites for properly conducting sensory analysis is choosing an appropriate number of samples and presenting them to tasters in the relevant sequence.
The method describes the appropriate procedure for sample collection of adjuncts, barley and malt.
Material, which is intended for processing in a food production facility, must be sampled prior to or at the time of delivery.
Hops and hop products intended for use in beer brewing or elsewhere in the food industry
A reliable sampling method for whole hops and hop products is a prerequisite for obtaining suitable material for analysis. The effort involved in collecting the sample depends upon how uniform the hop product is.
This method describes the conditions under which sensory analysis should be carried out.
beer, beer-based beverages, non-alcoholic beverages, mineral water
One of the basic prerequisites for properly conducting sensory analysis is establishing the appropriate duration of tasting and evaluating samples.
This method describes the conditions under which sensory analysis should be carried out.
beer, beer-based beverages, non-alcoholic beverages, mineral water
The basic prerequisites for properly conducting sensory analysis include assigning random numbers to samples which can later be referenced correctly to the results as well as employing the correct pouring technique when pouring the samples into the tasting glasses.
