Hi i ordered a breakfast stout kit from northerbrewer.com (all grain). I don't know when to add the 1lbs of lactose. The kit doesn't really come with directions like they do from midwestsupply and this is only my 2nd all grain. Also it has a mash schedule of 152f for 60 min then 170 for 10 min. When for 60 min is done do i just add enough boiling water to bring it up to 170? thanks for your help
