Her er teorien bak det:
"To reduce and eventually terminate the beta amylase activity and to ensure that all starch in the wort has been converted (especially the small starch granules which have a higher gelatinization temperature), a dextrinization rest is held at 158 - 162 *F (70 - 72 *C). At this temperature the beta amylase is quickly deactivated and only the alpha amylase works on the starches. The rest is held until the mash is iodine negative (no starch or long dextrines in the wort). Narziss [Narziss, 2005] and Fix [Fix, 1999] suggest, that a rest at 158 - 162 *F (70 - 72 *C) benefits head retention and body of the beer though glycoproteides that are extracted from the malt but not degraded by enzymatic activity. Because of that Narziss suggests holding this rest up to 60 min." http://braukaiser.com/wiki/index.php?title=Decoction_Mashing
Jeg har brukt dette i det siste, og tror at det kan ha noe for seg når det gjelder munnfølelse, og dessuten "maltiness", og muligens utbyttet. Men NB: "tror", jeg vil ikke påstå noe bastant. Andre som bruker det?
