Quick Answer
Acorn coffee can be made using leached acorns, but it requires a proper leaching process and roasting to develop the flavor.
Leaching Acorns
To leach acorns, you’ll need to remove tannins, which give them a bitter taste. Start by collecting 2-3 cups of acorns and cracking them to release the tannins. Rinse the acorns under cold running water, then soak them in a container with a lid for 24 hours, changing the water every 8 hours. After leaching, your acorns should taste slightly sweet and have a soft texture.
Roasting Acorns
To make acorn coffee, roast your leached acorns at 350°F (175°C) for 10-15 minutes, stirring occasionally. Check the acorns frequently to avoid burning. Once roasted, let the acorns cool completely. You can then grind them into a fine powder using a coffee grinder or mortar and pestle.
Making Acorn Coffee
To make acorn coffee, combine 1 tablespoon of ground acorns with 8 ounces of hot water in a filter or French press. Steep for 3-5 minutes, depending on your desired strength. Strain the coffee and serve immediately. You can adjust the ratio of acorns to water to suit your taste. Note that acorn coffee has a distinct, slightly sweet flavor that may take some getting used to.
