How To Roast Your Own Green Coffee Beans – Setup

If youre looking for an alternative way to add flavor to your coffee, you have a couple of options.

You can add a few drops of vanilla extract or peppermint oil during the brewing process to make your coffee a little sweeter. You can also sprinkle cinnamon on your coffee, too. This also gives it an aesthetic, coffee shop look.

You can add different types of milk including coconut milk, almond milk, or cow milk! Cream and sugar are great options to make bitter coffees sweeter.

Easy Steps To Roast Coffee At Home

Here is a step by step process of how to perfectly roast coffee beans at home.

  • Buy unroasted green beans: You can find these beans online, at your local supermarket or even at a farmers market.
  • Preheat the oven: Heat your oven up to a temperature of 450 degrees and get your roaster ready.
  • Lay out the beans: Figure out how many beans you need to roast and measure them out. Now is a great time to use your scale for accuracy.
  • Roast for 5 minutes: Make sure to have a timer on hand and roast your beans for exactly five minutes. This may need to be adjusted depending on the type of roast you like.
  • Cool the beans: Take the beans out and place them on a separate bowl or pan. You will need to leave them for a few hours until they are done cooling off.
  • Allow the beans to rest and degas: During this stage, your beans will expel carbon dioxide, put them in a mostly sealed container and leave them for a couple of days.
  • Grind your coffee beans: Once your beans are done processing, its time to put them in the grinder. Decide what type of coffee you are going to make and grind the beans to the proper consistency.
  • Steep and press: All you need to do after grinding is get them ready for the coffee machine and make your favorite cup of joe.
  • Separate The Chaff And Let The Coffee Cool Before Storing

    Using a colander or your coffee roasters built-in chaff collector, separate your roasted beans from the chaff, which is the gold-colored outer skin. Let the coffee cool and store it in a non-airtight container overnight. This will allow the freshly-roasted beans to degas.

    About 24 hours after roasting, your coffee will be at its most flavorful. Grind your beans just before brewing and store the remainder in an opaque, airtight container. Youll be amazed at the vibrant flavor, strong aroma, and impressive bloom.

    What Are The Benefits Of Roasting Your Own Coffee Beans

    Besides the fact that you get to craft your coffee from start to finish, you also get to learn some new skills. Learning to roast doesnt take too long once you have all the equipment and establish a good roasting routine.

    You also get to enjoy coffee the way its meant to be tasted. When you roast your own coffee, you will know where the beans come from, what the base flavors are, and what the bean went through before reaching your cup.

    Another huge benefit is that because you pick the roast level, its easy to control the flavor of your coffee. Roast level can determine how complex it is , how balanced and earthy it is , or how sweet and caramelized or smoky it is .

    Caffeine level is also controlled by the roast. Light roast beans contain slightly more caffeine than their dark roast counterparts. If you want a lot of caffeine, leave it lightly roasted, but if caffeine level isnt as important, then medium and dark roasts develop great flavors.

    Roasting For Filter Or Espresso

    How To Roast Coffee Beans: 5 Ways to Roast Your Own Coffee ...

    Have you ever thought what actually is the difference between filter and espresso coffee? Filter extraction is done by gravity and its process is quite gentle. You may use very aromatic and more acidic coffee for filter. On the other hand espresso is extracted with a 9 bar pressure. That means more flavour is extracted to the cup. Sometimes coffee roasted for espresso might not be as good when brewed as filter coffee and vice versa. Some roastmasters want to roast only for the bean and not for the extraction method which means the aim for golden middle way between too light and too dark so that coffee is suitable for both.

    Traditionally espresso is dark roasted coffee with low acidity and big body. Filter coffee is roasted differently in different countries, but roast degree is typically lighter than for espresso. Nowadays roast styles are more flexible than traditionally. For example, our Ethiopia Amaro Gayo espresso was third in Helsinki Coffee Festival espresso competition. The espresso was light roasted with a fast profile which made it really aromatic with low roastiness. Body was rather juicy than heavy. On the other hand, we want some of our coffees be more full bodied as espressos. Then we roast a little bit longer and make the development stage longer to develop flavour and decrease acidity.

    How To Do It In A Pan

    Roasting coffee in a pan is similar to roasting nuts. Heat the pan to 200-220 degrees and then distribute the green coffee beans in it. It is important to stir the beans over and over again so that they are evenly roasted from all sides. After about 5 to 10 minutes, the beans begin to crack and steam. Since there will be some slight smoke, you should at this point switch on ventilation and/or open the window. After about 17 minutes, the second crackling of the beans will happen. That means that the pan can be removed from the stove. The roasting time can, of course, be shortened or extended depending on the aroma and flavor you want to get. To cool down, transfer the beans to a dry, cold container.

    With A Popcorn Popper

    Roasting coffee beans in a hot air popcorn popper is popular with people who roast coffee at home but arent ready to invest in more expensive equipment. After all, popcorn poppers are quite cheap and easy to find.


    • No way to regulate the temperature
    • Beans tends to roast too fast and can taste underdeveloped
    • Chaff gets all over your roasting space

    When choosing a popper, dont use one that has a mesh screen and heating element at the bottom of the popper. This will blow your beans upwards, and potentially knock them out of the popper.

    Also, that mesh screen in the bottom creates a problem with the chaff. Chaff is dried husk, or skin, that still clings to unroasted coffee. When you roast the bean, the light chaff loosens off. Chaff can get stuck in that bottom screen and create a fire hazard.

    To avoid those problems, choose a hot air popcorn popper that has the air vents on the side. Side vents move the beans around in a circle and dont let the chaff get stuck.

    Also, choose a sturdy popper that will stand up to long roasting sessions. It takes longer to roast beans than to pop corn, and many poppers cant stand up to the heat. The plastic lids are especially prone to melting.

    What do you need to roast in a popcorn popper?

    • Unroasted coffee
    • Oven mitts or kitchen towels

    How to do it

    Step 1
    Step 2

    Place about ½ cup of beans in the bottom of the popper. You dont want to fill the chamber because the beans wont reach a high enough temperature.

    Different Coffee Bean Flavors

    How To Roast Your Own Coffee Beans

    Seasoned coffee roasters will tell you that there is a timeline in which the roasting process happens. Using your eyes, ears, and nose will tell you everything you need to know about the roasting timeline.

    Once the heat is on and the beans are roasting, the first stage you will come to is the first crack stage. There will be a snapping or popping sound and the beans will have expanded slightly with a matte light brown exterior.

    The aroma from the first crack stage is similar to baking yeasted bread. This is the first stage in which your roasted coffee beans are drinkable, also known as a light roast.

    The second event on the coffee roasting timeline is the second crack in which you will hear a louder, more violent cracking noise. The outer shell becomes deeper matte brown with a toasted chocolatey aroma.

    This is also known as the medium roast stage, with deeper, more complex notes than light roast coffee.

    Continuing to roast your beans further will result in an oily sheen emerging on the beans with deep, dark, roasted notes. You may notice a soft smoke at this stage, and that is normal.

    The end-stage is French roast, the most roasted type of coffee beans. This is the last stage that roasted coffee beans are drinkable. Any darker and the beans will be burnt and unpleasant.

    Once the beans are roasted to your liking, cool them immediately to stop the roasting. Move them away from the heat and place a fan on them if possible to keep the air circulating.

    Can You Use A Popcorn Popper To Roast Coffee Beans

    The good news is that you can roast coffee beans in a popcorn popper! The bad news is that you cant do it as efficiently as other roasters. The reason for this is the popcorn popper does not heat up the beans evenly. This makes the process take longer and beans will end up with a more uneven roast. The other problem is that the popcorn popper doesnt produce much pressure. This means that the coffee beans stop roasting before they are done and for the same reason, this roasting process takes longer. Still, this is an option for those who want to try something new but want to stick with old technology. In fact, I tried this method a long time ago and it sort of worked although the coffee didnt taste as good as the one from coffee roasters. Roasting coffee beans can make a mess, so I recommend doing it either outside or in the bathroom.

    Here is a guide to how to roast coffee beans in a popcorn popper:

  • Start by pouring 1/2 cup of raw, green coffee beans into the popcorn popper.
  • Set the popcorn popper on high heat.
  • Now, its time to wait for it to finish popping that should take about 12 minutes.
  • Once thats done, its time to smell the aroma of roasted coffee beans.
  • Understanding The Roxasting Process

    In this article, weve provided you with step-by-step instructions for each of the four home methods. Your exact approach to roasting will vary depending on your chosen method.

    But what never changes is the process:

  • Beans get hot
  • Beans get delicious
    • Save

    Its a simple process with some necessary steps to note along the way to guarantee great results. These important steps hold true for every method.

    Using Your Oven To Roast Coffee

  • 1Open a window and turn on your stove fan to vent the smoke. Be prepared for smoke to be produced by the roasting process. Turn on your stovetop vent fan, if you have one. Open a nearby window to vent additional smoke. Know where your smoke detector is and be prepared to turn it off. Keep a towel nearby to fan the smoke away from the smoke detector, if needed.XResearch source
  • Do not remove the batteries from your smoke detector.
  • 2Preheat your oven to 250 °C to begin the process. Put a thermometer inside your oven, if you do not already have one. Make sure there is one rack in the middle of the oven and wait until the oven is preheated before placing your green coffee beans inside.XResearch source
  • Keep in mind that the ovens temperature will decrease each time you open the door, therefore the thermometer will be more accurate than your ovens controls.
  • Feel free to remove other racks from inside the oven if you wish. Only one rack is needed for roasting coffee.
  • 3Place the green coffee beans into a perforated metal pan in a single layer. Only add enough green coffee beans to cover the bottom of the perforated pan do not allow the beans to pile up on top of each other. You want the beans to each to receive the same amount of heat during the roasting process.XResearch source
  • Green coffee beans can be purchased at a local coffee roastery or at a coffee store online.
  • You will need to roast your green coffee beans in batches unless you only purchased a small amount.
  • Set Up Your Home Roastery

    For most roasting methods, you will want to set up a home roasting station where you have all your equipment on hand.

    Choose an area thats well-ventilated. You dont want to go to an extreme and have a chilly, breezy space. Simply pick a space where any smoke, chaff, and odors can escape. You can use a fan as an extractor, open a window, or roast in your garage or enclosed patio.

    What equipment will you need to have on hand? That depends on what roaster you have, but it may include tools to weigh or measure the beans, what youll use to handle hot items, and what youll cool the beans with.

    What Happens When You Roast Coffee Beans

    While the technique may seem straightforward, theres more going on during home roasting than meets the eye. Theres a chemical process taking place at the molecular level that transforms more than 800 compounds in the beans from flavorless and raw into aromatic and delicious.

    Heres whats happening, according to Giuliano: First, as you heat the beans, the tiny reserves of water they hold evaporates, reducing the mass of the beans by around 11 percent. After about three to five minutes, when the last bit of water escapes, it turns to steam and causes the coffee beans to pop and crack.

    A few minutes later, the second pop or crack is the result of carbon dioxide created during the roasting process. The beans will continue to release this carbon dioxide for hours, even days after roasting is complete.

    And its all because of heat. Giuliano says, The heat causes a variety of chemical reactions, including pyrolysisa process of temperature-induced decomposition of coffee materialand Maillard reactions wherein sugars and proteins turn deep brown. This is similar to whats happening when foods like steak and toast brown and develop rich flavors.

    Every type of coffee has a unique chemical reaction, but Giuliano says a skilled roaster knows how to coax a roast along and, more importantly, when to stop to get exactly the flavors they are looking for. Its a skill that only comes with practice.
