  BT - Troubleshooter: Water Hardness, Dextrin Malt, Malt Shelf Life, and Careers in Brewing
DM: Dextrin malt is made by a complicated process that is proprietary to the manufacturer, Briess Malting Company.
Basically, the malting conditions are so manipulated that the sugars and dextrins are changed into nonfermentable isomers that also cannot be attacked by the malt enzymes, alpha and beta amylase.
Dextrin malt is most useful in lager beers because lager yeasts use more of the triple sugars in wort and thus generally give a lower terminal gravity, and a lighter body, than ale yeasts working on a wort of similar starting gravity.
