Canadian Imperial Stout - comments please

I did this as a extract brew and it was good but now I would like to redo as a AG. Here is what beersmith gave after the conversion. Let me know what you think, this will be my 5th AG brew.

bottle using more maple syrup. I would have to look up the original recipe again to get the priming amount. The syrup that I used the first time and will use again is from my dad's 40 acres that the amish cooked up.

A couple of thoughts:

1 lb of roasted barley will give you a lot of roast-y flavor in your stout. Although this is an imperial stout, so maybe it balances out. I usually use about half of that amount for a 5.5 gallon batch of regular strength stout sweet-stout

3 lbs of maple syrup seems like a lot.

I wouldn't use a 'C' hop like Cascade in a stout - I don't want the citrus flavor and aroma.

here is the original recipe that i got out of the home brewers recipe guide.
10lbs amber malt
1qt canadian maple syrup
1lb roasted barley
1/2lb crystal 40L or greater
1/4lb chocolate
1/4lb black patent
4oz northern brewer 60min
4oz fuggles 30min
1oz cascade 10min

1/2qt maple syrup in full boil and the other half at 10min

Wow that's going to be way beyond hoppy maybe the sweetness from the maple syrup will help to mellow the hops. What is your BU:GU ratio

 

[seabeemech1970]

Just did the ratio its like 1.275 OMG hoppy

Here is a few adjustments. I think the original hop amount was due to the recipe for extract was writen as a partial boil.

Still have the cascade in there, I need to do some more research to see what I would like to replace them with if I do.

Try replacing the cascade with nuggets or millennium hops
