I couldn't find anything in the search...I know this aids in head retention and such and can be used to balance body of darker beers. But if doing an extract recipe to you steep dextrine with your other specialty grains or do you add it late?
I add my malto dextrine powder at the beginning of the boil with my bittering hops for my dark beers, and about 15 min prior to the end of the boil for light colored beers. I have no idea why i do this, it comes from my early beer kit brewing days. That was what the directions for those different styles said in the instructions. Maybe one of the gurus on here knows why
I don't thinks its very fermentable, so not sure why it couldn't go in any time from beginning of boil to bottling. I know a guy that puts his in at bottling time, but he also adds it to his creatin....
