6 steps for this task

  1. 01Reach the upstairs coffee station.Talk to Kate, then go through the main hall to the second floor. Find the coffee grinder and the mansion painting.
  2. 02Read both clues.Light every window in the mansion painting. Back in the main hall, read the portraits' finger directions: William points left, Alexandra points up, and Aldous points right.
  3. 03Open the coffee box.Combine the window and finger clues at the upstairs painting and enter 315 in the servant-room box. Take the coffee beans.
  4. 04Roast whole beans for Favorite Coffee.Optional achievementUse the whole beans on the top surface of the stove, beside the pot. Do this before grinding; putting unroasted beans into the brewing pot is not the roasting step.
  5. 05Grind, brew, and serve.Take the roasted beans to the upstairs grinder. Put the resulting coffee powder in the stove pot, collect the brewed coffee, and pour it into Aldous's cup. If you already ground the beans first, that attempt has missed the documented roast-before-grind achievement order.
  6. 06Continue to William.Talk to Kate upstairs, then enter the guest room.
