High-end coffee doesn’t usually lend itself to such moments. Instead, it’s something to be fussed over and praised; you talk more about its origin and its roaster, its flavor notes and its brewing method than you talk to the person you’re enjoying it with. Bad coffee is the stuff you make a full pot of on the weekends just in case some friends stop by. It’s what you sip when you’re alone at the mechanic’s shop getting your oil change, thinking about where your life has taken you; what you nurse as you wait for a loved one to get through a tough surgery. It’s the Sanka you share with an elderly great aunt while listening to her tell stories you’ve heard a thousand times before. Bad coffee is there for you. It is bottomless. It is perfect.
