wow, i cant believe my first post could be more helpful then questioning!
i was looking for a place to ask this question, but wanted to see if someone else asked it first. your post looked about right to me, so i read on. what you describe sounds a lot like what i want to make. here is a review i read that got me started.
"Samuel Adams Cream Stout
Pours in the glass a rich dark brown, nearly black. The head is two fingers of firm tight camel coloroed foam. The lacing is very thick and sticky.
The smell is sweet caramel malt, dark roasted coffee beans, light butter toffee, and a subtle earthiness.
The taste has a mild sweetness up front. Smoky and charred notes with light hop bittering in the finish. There is smoke in the aftertaste.
Medium-heavy body. Fairly light on carbonation. Creamy mouthfeel.
Very enjoyable. Highly drinkable."
i think the lactose from milk is a sugar that wont ferment as well, like even suggested. but i gotta try some body building beer, what a concept! maybe we can get a workout routine to go along with drinking that brew, i could justify it to the wife then. LOL
