Acorn Coffee Recipe

Acorn is the nut of the oak tree. Did you know that you can eat acorns and even make naturally caffeine-free acorn coffee. You will be surprised what a beautiful nutty and caramel flavour it has. You cam use ready-made acorn meal or forage and roast your own acorns. It does take a bit of time to prepare them, but it could be a fun activity to enjoy with your kids and family. Acorns are usually safe for tree-nut allergy sufferers, but please double-check if unsure.

  • Method for Acorn Coffee
  • In a small boiling pan combine the acorn coffee powder, water and salt. Boil for 5 to10 minutes, stir well and set aside.
  • The acorn powder will swell and create a thicker sediment on the bottom of the boiling pan but you will only need the infused liquid.
  • In a different boiling pan, heat almond/rice milk until hot, but not boiling.
  • Pour the infused acorn coffee/liquid into the mugs you prepared earlier (it will make approximately 1/2 a mug).
  • Top it up with heated almond/rice milk.
  • Add one teaspoon of honey or other sweetener.
  • Note: You also can make a black acorn coffee without milk. Feel free to add more or less acorn powder per serving.
  • -------------------------------------------
  • Method for  acorn powder / flour / meal
  • Make sure you pick acorns under a White Oak (Quercus alba), not the Red Oak (Quercus rubra). The Red Oak has pointy leaves and the acorns will have a more bitter flavour because they contain more tannins.
  • Pick the acorns.
  • Inspect the acorns and discard the ones which have holes or big cracks in them.
  • Boil the acorns with shell on for 30 minutes. It will make the shell a bit softer and easy to remove.
  • Shell and peel the acorns: Let the acorns cool down a bit. Cut them in half and take the acorn out. Discard if they are black or mouldy. After shelling, try to remove as much skin as possible.
  • Cut the acorns into smaller pieces or use a food processor.
  • Roast them in a dry cast iron pan or in a warm oven until they become dark and very dry.
  • Grind them in a coffee grinder. After this step you can return them back to the pan for roasting, if you think it is necessary.
