• The extent of malt milling is of crucial importance
in brewing with regard to the efficiency of mashing and extract
• There is generally no preferred method of milling for producing
cask conditioned beer, providing that cloudy worts are avoided.
• Mill settings (ie. gaps between rollers) will be influenced by
the corn size of the malt.
• The optimum particle size of malt grist depends on the mashing
and wort separation system employed.
Range of Values - Typical values for the sieve analysis
of grists used in different systems are as follows:
|Sieve mesh size (mm)
Values represent the percentage of the grist retained
on each sieve. A high proportion of husk is retained on the sieve
of mesh size 1.3 mm.
Sieve analysis should be carried out on samples
of grist at least every 7 days. Check sieves for wear after approximately
The gaps between the rollers of mills should be checked at several
points across the rollers when there are changes in grist analyses
or mash tun performance. Replace or regrind worn sets of rollers.
• A set of feeler gauges, range 0·25 - 1·75 mm
(10 - 70 thousandths of an inch), is required for checking mill
• Suitable sieves for grist analysis are available from Endecotts
