It probably needs a bit of extra malt, and a tad bit more dark steeping grains. It also needs some extra hops. Definately for bitterness, aroma, and flavor. But I am not sure were to start.
Any suggestions?
You would need to steep or do a PM with a bit of roasted barley and some acidulated malt if you really want to get the vibe of the beer. A 5 gallon batch of something like guiness would have around 2-3oz of acidulated malt and about 12oz-16oz of roasted barley and a couple of pounds of flaked barley, the rest being 2-row to get to your target gravity. Or something there about. (I can't give you an exact number but it's in those ranges somewhere). And around 40-45 IBUs of hops, all just bittering additions.
If you can do a PM, I would PM some subset of the above with enough 2-row so that when you add your can of extract you are between 1.06-1.07 if you are going for the extra stout/foreign export vibe, not the pub draft vibe. (pub draft is much lower abv, but similar ingredients).
Hard to say exactly how much. I would use the same proportion of acidulated malt, but less roasted barley and flaked barley proportionally since the extract will give you some of those flavors. But it won't give you the acidulated malt sourness. And yes Guinness has this. They supposedly sour mash some of their wort and add it to unsoured wort. But it's a lot easier to use acidulated malt for homebrew purposes.
If you can't/don't want to PM, then maybe steep just the acidulated malt, and pick up some Briess CBW Special Dark (NOT Traditional Dark) LME, and use it to make up the gravity difference, and boil enough hops in that to make up the IBU difference. Briess Special Dark is just 2-row and roasted barley, nothing else. It's the extract I'd use to make a guiness clone if I wasn't going to mash. I'd just steep some acidulated malt, and use that extract and some hops.
You should use liquid irish stout yeast if you can, otherwise I'd suggest Danstar Windsor yeast. S-04 would work but it's not going to quite give you the same vibe.
That's what I can tell ya...
