What do you think of this Chocolate Stout Recipe?

I was at my LHBS this weekend and they set me up with these ingredients for a chocolate stout.

This is a partial mash recipe.

3.0 Lbs LME

5.25 Lbs Maris Otter Malt

0.75 Lbs Chocolate Malt

0.50 Lbs Crystal 60L Malt

1.0 oz Sovereign Hops 5.7% AAU (60 Min)

5.0 oz Cocoa Nibs (2.5 oz @ 15 mins / 2.5 oz in secondary)

Wyeast 1098 British Ale Yeast

Please let me know what you think. I'm happy to adjust the recipe based on suggestions. Thanks in advance!!

I'd thrown in some roasted barley and do all of the nibs in secondary.

I was thinking 6 oz of cocoa powder about 10 mins from the end of the boil and using all of the nibs in the secondary. Will that be to chocolaty?

I use 8 oz. of nibs in a 5 gallon batch which is perfect for my tastes. I prefer the taste of nibs to powder, but I know a lot of people use powder at flame out. I don't think 6 oz. would be too much, but make sure you are using powder that doesn't contain fat or sugar.

any particular brand of cocoa powder? Also, how much roasted barley? I can't handle too much more grain than I have.

Winderslim makes a fat free cocoa powder that works great for brewing.

Here is mine, its all grain. I will post a PM in a minute.

Thanks for the help! Will the sovereign hops work ok for a chocolate stout? LHBS said that this beer should really only have bittering hops.

Anybody? Just trying to find out of Sovereign hops are a good bittering hop for chocolate stout.
