Brewed up NB's milk chocolate stout a week ago. Added some additional grains for a mini mash - a 1/2 pound of oats and a 1/2 pound of pale malt, which I combined with their steeping grains. The recipe also has a pound of lactose, which I know is non-fermentable. Pitched one packet of rehydrated Safale 04 and fermented around 65-66 for the week. Gravity this morning was 1.030. I mashed around 156 because I wanted a sweeter beer. Should I assume it will continue to drop and finish around 1.025 or would you add more yeast? I have some harvested 1098 on hand I have used for stouts before with good success so I thought about making a small starter and pitching that at high krausen, but part of me says let it go another week and see where it's at next weekend. Right now it's at 4.4% as OG was 1.063. Thanks.
