How to roast green coffee beans at home?
Have you taken it as a DIY project to roast green coffee beans at home? Let’s discuss some more on this topic.
One of the main advantages of roasting green coffee beans at home is that these coffee beans will cost less per unit weight than roasted coffee- almost 30-75% cheaper.
You can have coffee for your espresso machine for a week or so by just roasting it for 15 minutes. Yes, it is definitely less time taking!
The best part about roasting coffee beans at home is that you don’t need any extra things to continue with the process. Roasting beans require utensils and electrical appliances that are commonly found in every home. All you need is green beans, roasting equipment and a place to store the freshly roasted beans.
There are multiple methods to roast coffee beans at home.
How to roast coffee beans in a pan?
2 So roasting beans in a pan is the most feasible method according to me. The process requires things that you most probably already have at your homes. This method can be a little problematic but still, I urge you to use this method at least once to experience the magic of coffee roasting.
When we talk about the pan, we generally refer to a frying pan but you can use any pan that could be put on the burner. It would be better if you use a utensil with a nice round bottom wok. The pan should be made up of thick metal without any kind of coating.
Other equipment to be used is a colander and a lid.
Switch on the chimney guys. We are going to start with the process.
Preheat the pan by putting it on the burner/stove. Medium-high temperature does the work. The reason to preheat the pan is that the coffee beans are roasted quite quickly this way without being exposed to the heat for a long duration of time.
Once you have heated the pan, add the green/raw beans to the pan. It’s better if you add a large number of beans to the pan since the double layer restricts the direct contact of beans with the heat.
Now that you have added the beans, it’s your responsibility to make sure that the beans cook (and not burn) evenly.
So here comes the role of the lid. Covering the pan with a lid helps the heat to be trapped inside the pan and thus the beans are roasted evenly. You can also shake up the pan easily with the help of a lid.
It’s good to stir the beans after every 25-30 seconds so that the position of beans keep changing and they are not in contact with direct heat for a long time.
Halfway through the roasting, the beans will acquire a dark colour.
Now comes the critical part. You will notice the coffee beans producing two cracks while being roasted. It’s better to have coffee beans between the two cracks to ensure more caffeine in your coffee.
So now that we have done all the work, we need to cool down the coffee beans as soon as possible so that they don’t give away a bitter taste after being brewed in the coffee maker. This can be done with the help of a colander.
Spill the coffee beans into the colander. The cool metallic base of the utensil will cool down the coffee beans and its structure will provide them with the much-needed air.
Once you have poured the coffee beans into the colander, gently swirl the colander and blow on the beans while you do so. This is done to separate the husk from the beans.
Now your work is done! Let the beans rest for a day or so.
How to roast coffee beans in an oven?
Now that we have learnt to roast green coffee beans in a pan, let’s find out how to roast green coffee beans in an oven.
Things that you would need to continue with the process-
- An oven that can reach a high temperature.
- A baking tray or a cooking sheet.
- A stopwatch
- An oven mitt, Oven glove
- A wooden spatula
- A metal colander
- A water bottle with a mist spray
- Green coffee beans
The first step is to preheat the oven. Different ovens have different heating capacities. The ideal temperature to preheat the oven is between 475F-500F. Keep a flashlight handy if your oven doesn’t have a working light. This helps later on.
Take a baking pan which has small perforation so that the beans don’t get stuck in the large perforations and expand.
Pour the beans into the baking pan and spread them. Make sure they are still close together.
Open windows or switch on your chimney guys. The real action begins now.
Prepare for the things that would be needed to cool down the temperature of the coffee beans. You would need the metal colander and water spray for this purpose.
Set the baking pan inside the oven after it has been preheated. Since you are ready with your cooling strategies, you can now monitor the roast. Start your stopwatch. The best way to monitor the roast is by observing the colour of the beans. The beans would turn from green to yellow to light brown and finally to dark brown.
Sometimes the beans spread on the edges start roasting faster and thus you need to take out the tray, use your wooden spatula to reposition the beans and quickly set the baking tray back in the oven. This is to ensure even roasting of coffee beans. This can only be done twice.
Another method to observe the roasting is my listening to the popping sound that the beans make during the first crack. The second crack has a crackling sound. You will get to know when to take out your beans with the help of the sound and colour of the beans.
Usually, the beans take 10-17 minutes to roast depending on the heating capacity of the oven.
Once you take out the coffee beans, immediately pour them into the colander. It’s very important to cool down the temperature of the beans to the room temperature so that they taste good after being brewed.
Now swirl the colander. Shake and blow off the chaff. Apply the water mist.
Let the beans settle down for a day at least before using them.
How to roast coffee green coffee beans in a popcorn popper?
Wondering how to roast coffee green coffee beans in a popcorn popper? Well, we are here to help you out.
What you need?
- 1500 watt west bend poppery
- Empty soup can/fitted dryer vent
- Wooden spatula
- Salter kitchen scale
- 2 metal colanders.
- Tupperware bottom
- Black marker
- Airtight container
- A duster
- Your favourite green coffee beans.
Roasting coffee beans can produce a lot of smoke and thus you need to be prepared for it. It’s better if you find a spot outside. If the popper has a plastic lid, you got to remove that. The soup can should be opened and cleaned from both the sides. The can would be used as a chimney so you have to make sure that it fits snuggly into the top of the popper.
You can use any popcorn popper but I recommend 1500watt west bend peppery.
Warm up the machine while you prepare for the roasting.
Pour about 100-150grams of coffee beans into the Tupperware bottom with the help of the kitchen scale. Now pour the beans into the popper slowly. There are different reactions produced by the machine when you add the beans to it.
The beans may spin in a circle and this means that you can add more coffee beans in the machine.
If the beans dance in a random pattern, then congrats! You have added the correct amount of coffee beans to the machine.
If the beans aren’t moving, that probably means that you have added a lot of beans and you need to take out some.
The chaff ( skin of the beans) begins to come out during roasting. You can remove this chaff either during the roasting or after the roasting. Stir the beans with the wooden spatula to remove the chaff.
The beans have a tendency to become lightweight after being half roasted. This propulses them to pop out of the popper. Here comes the role of the soup can. Place the open end of the can on top of the roaster to keep the beans inside the popper.
Now comes the task to monitor the roasting. Sound and colour are two important things that should be taken into notice while you are roasting the beans.
We have already discussed when to interpret that the beans have been roasted. The pattern remains the same.
Once you switch off the roaster and take off the soup can with the help of the spatula, spill the beans into the colander. Pour the coffee beans from one colander to another to cool off the coffee beans.
Let them be for a day before brewing.
How to roast coffee beans in a cast iron skillet?
Here’s the guide on how to roast coffee beans in a cast iron skillet.
Cast iron is one of my favourite roasters to roast coffee beans since it evenly distributes heat without hotspots thus leading to evenly roasted beans.
It’s better to continue the process outside if you don’t have an efficient exhaust fan.
What all you need?
- Cast iron pad
- Outdoor camp stove
- Metal colander
- Wooden spatula
About half a cup beans are enough to be roasted at a time. Obviously, though, the amount will depend on your pan. One layer of coffee beans is enough.
Pre-heat the pan for around 500 degrees. After the pan is warmed, spill the coffee beans and stir them. You need to keep stirring the beans in slow and deliberate movements so as to keep the beans moving. This ensures even roasting of the beans. Stir them with the wooden spatula.
The beans will roast in about 8-10 minutes. You can roast it for a few more minutes depending on your preference for coffee colour. The beans shouldn’t darken unevenly.
You need to be really careful after the first crack. This can be the time when the beans get burned.
Pour the beans into the metal colander and shake it to cool down the coffee beans. The beans will release its chaff in the process.
Leave the beans open for a day.
Pour the beans into an airtight container the next day to keep them fresh for a long time.
I hope you all understood how to roast green coffee beans.
