Sure does look good on the outside. I can't see much color inside though. Too bad about the taste. I can't be certain, but one video I saw seemed to imply that the stout, after reduction of course, was added to fresh curds which were then mixed with aged curds, the fresh curds acting a bit like glue I'd imagine. not sure why I mention that, just something to consider I guess. I wonder if maybe you'd consider trying both the addition as you have it, and then back it up with a stout soak for a little punch. How was the horseradish? I've been thinking of doing one of those, in a gouda, but haven't gotten round to it. Maybe even wasabi!
