I made acorn acorn coffee today! 😀
I used a knife to peel the freshly gathered acorns, it’s easier than I thought: like peeling chestnuts.
I soaked the acorns in water for some days to remove the tannins, changing the water frequently till the acorns stop coloring the water yellow. Then I roasted the acorns and grinded them in a mortar to fine powder.
To make the coffee: I used 1 tsp ground acorn coffee per each cup of water, brought it to a boil, and the acorn coffee is ready to drink. While roasting the acorns it smelled like coffee, but the acorn coffee tastes only remotely like coffee.
