I am making this right now as my second ever all grain batch! For coffee, using some Royal Kona coffee delivered straight from Hawaii

. Using 2.5 oz of grounds at flameout, then I'll add some brewed Kona when I keg.
This wort tastes amazing! We actually stole a sample pre-boil and SWMBO is going to try making a "Breakfast Stout reduction sauce" to put on top of some pancakes!
