After four weeks in the bottle, mine had a carbonation issue. Very little carbonation on this beer. I wonder if my mint extract had some sort of artificial preservative in it that killed the yeast. I used S04 on it so i'll upgrade the yeast on the next batch. Feedback was positive and I even have a friend that want's a case, so i'm brewing it up in two weeks for him.
Positives: Great thick mouth feel, strong mint & strong chocolate flavor. Mellow and smooth with no hints of tannin due to the 48 hour roasted grain tea method.
Negatives: Lacking carbonation, no head, residual powdered chocolate in bottles, super strong mint & chocolate flavor, hops completely overpowered.
Fix for version 2.0 (to be brewed weekend after next): Switch to celestial seasonings mint tea bags for tea addition, dial back the powdered cocoa by 1/2, strain through coffee filter to remove cocoa powder, use Irish or Scottish ale yeast.
