Alcohol boost from raspberries?

[kevmoron]

I brewed an export strength stout today at OG 1.070 and am using Wyeast 1388 Belgian Strong Ale to ferment it. I plan on tossing in 3 Lbs of raspberries in the secondary. For those with experience using raspberries, what is the gravity/alcohol contribution of a pound in 5 gallons?

It will be minimal, I would say about 0.3% or so max.

Yeah, you won't get much. I doubt you will notice them much at that level (flavor or alcohol).
