How to make black coffee
Purchase freshly roasted, whole bean coffee.
If you can't purchase it directly from the roaster within a week or so of it being roasted, opt for a vacuum-sealed bag from a reputable national coffee-bean roaster.
Purchase your own coffee grinder, or grind it in the store.
If possible, choose a burr grinder in place of a normal blade grinder. For best results, grind the coffee fresh right before brewing each day.
