So an update! i brewed the beer this way.
1 hour Boil - 4 litre boil
15 mins in add 1 oz of nugget hops
Added 500 gram of brown sugar
500 gram of dextrose
4 pounds of liquid Pale malt
& Can of black rock stout in the early to mid part of the boil
@45 min of boil i added 0.7 oz of cascade hops
Primary 3 weeks
3 days in secondary with 2 cut vanilla beans
then bottle a twelve pack
and let sit in keg for another 8 days.
Well it is amazing all my craft buddies love it and say they would pay for it! It's complexed warming and leaves you with a slight taste of vanilla, it is exactly as i envisioned! it also somehow made it to 8%. I still have a good 2 gallons left! but people want more and i have to hide it!
I nearly named it Ogri stout for all your help but this semester was too painful.
Anyways thank you and here is a picture.
