Determination of the proportional composition of grist fractions through sieve analysis
Malt grist, grist from adjuncts
The extract yield in the brewhouse is highly dependent on optimal milling of the malt or other grain. The composition of the brewery grist should therefore be monitored on a regular basis.
The sieve analysis is performed on a sample of brewery grist of a known weight with a shaking device containing a set of sieves (according to DIN ISO 3310-1 specifications or a Pfungstädter plansifter sieving device).
This method describes the determination of the extract content of malt through the application of a complete extraction technique.
Malt intended for use in beer brewing or elsewhere in the food industry
Since the Congress mash method does not accurately quantify the extract content of malt, an attempt was made to eliminate the sources of error present in the method. The method described below incorporates the procedure for producing a Congress mash according to the EBC, followed by a complete extraction of the dissolved substances with a suitable apparatus. After the extraction is complete, the weight is determined. This method is preferred for determining brewhouse yield (e.g., during brewhouse equipment commissioning tests).
Water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
The level of carbonate removal in the water treatment system is monitored using the analysis for the p and m values. The standard values specified in the analysis should not be exceeded.
