add brown sugar in boil or in fermentation

[Matteo57]

I am designing a big huge imperial stout, around 14% abv. It has around 8% brown sugar in the batch. I am going to be boiling the wort for around 2 hours. Will adding the brown sugar at the beginning of the boil change the flavor much compaired to if I add it at around 3-4 days into fermentation? I would rather add it a couple days into fermentation to help the fermentation along better. Any thoughts?

Thanks!

With a beer that big, I always recommend people add the simple sugars late in fermentation. Too high a gravity wort can kill yeast.

I wouldn't expect it would change the taste.
