There are different types of coffee substitutes around the world. Examples of these substitutes are; chicory root, roasted cereal grain, and Acorn.

This article shall focus on Acorn coffee. What is the story behind using acorns to make coffee? How is it done? What are the benefits, if there are any?



Acorn is a fruit of an oak tree. It is one of the most critical wildlife foods where oaks grow. The time they mature depends on the species, ranging between 6 and 24 months. This nut often has a single seed enclosed in its rugged, leathery shell.

Birds, small mammals, and some big mammals feed on acorns, but the tannins are poisonous to other animals, like horses. However, you can get rid of the tannins with water.

Acorn coffee history can be traced back to the 17th century when Europe had no coffee beans. They improvised and used acorns that they had in abundance. During the American civil war, soldiers used ground acorns to substitute for their coffee.


Uses of Acorn

Acorn is helpful in a lot of ways. It can be eaten whole or ground up into acorn flour for bread, pastries, pancakes, cookies, and pasta. Acorn can also be made into mush and get the oil extracted.

Different uses of acorns require other preparation methods, such as leaching the tannins with cold or hot water and sprinkling with salt.


How to Make Acorn Coffee

Step 1: Gather your acorns

Handpick your acorns from oaks with the most significant green crop. The best time to pick your acorns is usually in October. That is the time when the first acorns start to fall. You should, however, desist from picking your acorns off the ground because squirrels or worms will have gotten to them first.

Step 2:Allow the acorns ripen

Your acorns were picked green, so you need to get them ripened. Pack them into a grocery bag for about a week and ensure the load is in a cool area.

Even if your acorns come in slightly brown, you should consider this step to allow your acorns to dry out and come out of the shell. Boiling would make your following process easier.

Step 3: Boil your acorns

The next step is for you to boil your acorns to make the shell more pliable. However, it would help if you inspected your acorns for any wormhole. These wormholes are signs of ruined acorns that are not suitable to use.

Step 4: Shell and peel the acorns

After boiling your acorns, allow them to cool down enough to be held. Get a knife to cut the acorns in half. A serrated knife is your best option to prevent the acorns from slipping.

It would help if you were patient with this step because it takes a lot of time.

Step 5: Roast your acorns

Just as coffee beans go through roasting, you need to roast your acorns as well. Ensure your acorns are completely dry before frying for about 5-8minutes on low heat.

Step 6: Grind your acorns

Toss your roasted acorns in a coffee grinder or food processor to turn them into grounds. You will have a fine powder, usually light brown.

Step 7: Re-roast

The goal is to substitute acorns for coffee, so the imitation should be almost on a 100, if not on a 100. Roast your acorn powder again to get the brown coffee colour.

Step 8: Brew your acorn coffee

Once you’re satisfied with the acorn colour, your acorn coffee making is up to you. Brew your acorn as you will brew your coffee. You are also free to add flavours of your choice.
