Flaked barley is for a bit of grain flavor, but mostly head retention. I added it because that’s what the recipe I used said to use… Not exactly a good reason, but it’s also pretty common in Irish Stouts.
I added some carbonation and your moka pot coffee trick, and that combination did the trick in my book. It’s much more interesting now.
Thanks for the tip!
