fermentables in fruit

[hassafort]

I am going to be brewing a raspberry stout. This is a partial mash brew, and I was wondering if anyone could tell me the estimated effect of 3 pounds raspberries on my abv. They will be going into the secondary.

Well, according to this nice little link I use (Sugar and Acid Content in Fruit) fresh raspberries are 7% sugar by weight. so this would come out to the equivalent of adding 3.36 oz of sugar to your brew.
