Haven't brewed for a while and thought somebody could give me advice on this recipe.
Haven't brewed many dark ales before so I am a bit confused about the amount of dark grains. I would like the roasty character to be smoother so don't want to go overboard, may be should have gone with some de-husked version but it's too late now I already ordered. I have read that black malt can give acrid taste to the beer but seen people using up to 10% and swearing by it ,don't know about choc though.
I guess smoked malt will be not enough to get the smoke character I am looking for, made a mistake when ordering but whatever

Would appreciate any advice.
Thanks
