Its kind of a hard one to explain, the initial taste really does a number on your pallet. I think the bubbles throw things off a bit,its usually followed by a strange look and a smirk🙂 I get a deep rich almost coco/chocolate taste but Ive only been using medium/dark roasts. I also dont water things down when its kegged. From what Ive learned abt the chemistry of it all a little Co2 is needed along with the Nitrogen, mainly because the nitrogen doesnt dissolve. Instead a certain amount bonds to proteins in the brew and changes the flavour,the cold brew from the same beans doesnt taste anything like the nitro brew! Im still working on a few things but I dont think sugar is going to be added before its kegged,maybe a simple sugar syrup in the glass before its poured. Im going to brew up some lighter roadts during the week along with a few other things, will keep you guys informed anyway🙂
