Hey, tell me how you did that! I've been wanting to brew a black and tan for a long time now, but I have never found the recipe!
Ha ha, but yeah, it's very normal. You can cold crash it to speed up the settling, or use gelatin or whatever. I just chill for a few days if I want the beer VERY clear.
Day after day, it reappears. Night after night my heartbeat shows the fear. Ghosts appear and fade away. Come back another day.
