stout recipe butchered?

[wackyvegan]

so yesterday a friend and i brewed an irish stout.the recipe and all ingredients were from a LHBS.

grains:
400g roasted barley(1200EBC)
400 flaked oat
3,7kg pale malt
0,3kg pilner malt

the recipe simply stated to mash in at 67°C and hold the temp for 90 mins with no further instructions.so we mashed in all the grains together but had a weird feeling about it because we thought the raosted barley should only go in for a few mins,and then be removed before the ´´real´´ mash in.was it a mistake to have the roasted barley for the entire 90mins in the mash?

You were correct to mash it with the rest of the grains, however I would say that on a percentage basis of the grain bill that is a bit much roasted barley. I usually use about 5% whereas your recipe is 8.3%- should be a dry, roasty stout but definitely not bad. Could have been balanced out with a bit of caramel malt. Enjoy!
