We experimented with every aspect of making coffee. What we found surprised us.
Over here at Decision Science News, we like Engineering All The Things. Accordingly, in an obsessive coffee phase, we acquired: A Coffee Maker that lets us set the exact brewing temperature A Digital Thermometer that lets us measure drinking temperature A Digital Scale that lets us weigh the grams A Coffee Grinder that lets us set the coarseness of the grind If you want to experiment, knock yourself out. What the figure above shows is that something around 55 grams of coffee per liter of water is considered ideal, but you can play around in the 50 to 65 grams / liter range. It’s harder to set where you want to be on the red lines without expensive equipment, but generally as you grind the coffee finer and brew longer you move up and to the right.
