Basic equipment for home roasting
Understanding coffee beans
Coffee beans are the essential starting point for home roasting coffee. To begin, it is crucial to understand the different types of coffee beans available. The two main categories are Arabica and Robusta. Arabica beans are known for their complex flavors, acidity and aroma. They are usually more expensive and considered of higher quality. On the other hand, Robusta beans are stronger in flavor, have a higher caffeine content and a more bitter taste.
Choosing the right beans
When choosing coffee beans for home roasting, consider factors such as origin, processing method and degree of roasting. The origin of the beans can have a big impact on the flavor profile, as beans from different regions have distinct characteristics. The processing method, be it washed, natural or honey process, also affects the taste. In addition, the degree of roasting – light, medium or dark – determines the final taste and aroma of the coffee. On this page we have gathered further information on what to consider when choosing the beans and buying your green coffee.
Basic roasting appliances
There are several basic roasting appliances available for home coffee roasting enthusiasts. Popular options are stoves and popcorn machines, which provide an easy and affordable way to roast coffee beans. These machines allow manual control over the roasting process, making it easy to monitor the beans as they develop flavor. Another common choice is the hot air popcorn machine which uses hot air to evenly roast the beans. This method is quick and efficient, producing consistent results with minimal effort. In addition, some home roasters opt for a cast iron skillet or a dedicated coffee machine for roasting. These options provide more control over the roasting process and allow for experimentation with different roast profiles.
Advanced roasting equipment
For those who want to take their home coffee roasting to the next level, advanced roasting appliances are available. Drum roasters are a popular choice among serious home roasters, offering precise temperature control and even roasting. These machines are capable of handling larger batches of beans and producing professional, high-quality results. We have a drum roaster at the roastery, a Giesen that holds 30 kr of green coffee. Another advanced option is a fluidbed roaster that uses hot air to roast the beans in a chamber, resulting in a clean and even roast. Some home roasters are also investing in hybrid roasters that combine elements of drum and fluidbed roasters for optimal control and flavor development.
Customized roasters
Custom roasters are designed for coffee enthusiasts who want full control over every aspect of the roasting process. These machines often come with advanced features such as customizable temperature profiles, airflow control, and data recording capabilities. Some custom roasters are modular, allowing users to upgrade or modify various components to suit their specific roasting preferences. While these appliances tend to be more expensive, they offer unrivaled precision and flexibility to roast coffee beans to perfection. Home roasters who are passionate about the art of coffee roasting may find that investing in a customized appliance is worth the cost for the ultimate roasting experience.
Proper ventilation
Having a well-designed ventilation system is essential for home coffee roasting to ensure the removal of smoke and odors generated during the roasting process. A proper ventilation installation usually consists of an exhaust fan placed close to the roasting equipment to capture the smoke at the source. This fan should be powerful enough to effectively remove the smoke and direct it outside the roasting area. In addition, installing a range hood above the roasting equipment can help to further contain and eliminate smoke.
Smoke control measures
In addition to ventilation, the implementation of smoke control measures can improve the overall roasting experience and minimize the impact of smoke on the surrounding environment. One effective method is to use a smoke suppressant agent that helps neutralize and reduce the intensity of smoke produced during roasting. These agents can be added to the roasting chamber or extraction system to facilitate smoke control. In addition, regular cleaning and maintenance of the ventilation system can prevent the build-up of deposits and ensure optimal performance in smoke extraction.
Air quality monitoring
To maintain a safe and healthy roasting environment, it is important to regularly monitor air quality. This can be achieved by using air quality sensors that detect the presence of smoke particles and other pollutants in the air. By keeping track of air quality levels, roasters can make adjustments to their ventilation system or roasting techniques as necessary to mitigate any potential health risks associated with poor air quality. Investing in air quality monitoring equipment is a proactive approach to ensuring a controlled and safe roasting environment for both the roaster and those around them.
Use of a thermometer
Monitoring roasting progress is essential to achieve the desired flavor profile in your home coffee roasting. One of the essential tools for this purpose is a thermometer. By measuring the temperature inside the roasting chamber, you can follow how the beans develop during the roasting process. Different roasting profiles require precise temperature control at different stages, from the drying phase to the first crack and beyond. A thermometer allows you to make real-time adjustments to the heat source to ensure consistent and even roasting.
Observation of color changes
Another way to monitor roasting progress is to observe the color changes of the coffee beans. As the beans are roasted, they undergo physical transformations that are visible to the naked eye. Carefully observe the color shift from green to yellow, then to various shades of brown as roasting progresses. Experienced home roasters often use visual cues along with scent and sound to determine the optimal time to finish roasting. Remember that different coffee varieties exhibit unique color changes, so it’s important to familiarize yourself with the specific beans you’re roasting.
Listen for audible clues
In addition to using visual cues and a thermometer, listening for audible cues is another effective way to monitor roasting progress. During the roasting process, coffee beans go through distinct stages that can be identified by the sound they produce. The first crack, a popping sound similar to popcorn, indicates that the beans are reaching a crucial stage of development. Subsequent cracks (second crack) indicate that the beans are progressing towards a darker roast. By listening carefully to these audio cues, you can make informed decisions about when to stop roasting to achieve the desired flavor profile. Experimenting with different degrees of roast while listening to the sounds can help you improve your roasting skills over time. At White Elk, we never roast into a second crack.
Correct storage container
When it comes to storing your freshly roasted coffee beans, choosing the right container is crucial. Choose airtight containers that can keep out light, air, moisture and odors. Glass jars with rubber seals or specially designed coffee storage jars are excellent choices. These containers will help preserve the flavor and aroma of your coffee beans for a longer period of time. Avoid using transparent glass containers as they let in light, which can potentially degrade the quality of your coffee.

Location and temperature
The storage location of your roasted coffee also plays a significant role in maintaining its freshness. Store your coffee in a cool, dark place away from direct sunlight, heat sources and moisture. Avoid storing coffee near the stove, oven or in the refrigerator as these areas can compromise the flavor and quality of your beans. Room temperature is ideal for preserving the freshness of your coffee beans.
Freshness monitoring
To ensure you enjoy your coffee at its best, it is important to regularly monitor the freshness of your beans. Keep an eye on the roast date and try to consume your coffee within a few weeks of roasting for optimal flavor. Consider labeling your containers with the roast date to help you keep track of freshness. Additionally, if your coffee beans start to lose their aroma and flavor, it may be time to consider roasting a fresh batch. By paying attention to these details, you can enjoy the full potential of your home-roasted coffee beans.
