When roasting coffee beans from Yirgacheffe or nearby Sidamo, floral and fruity notes emerge with hints of citrus and berries. Yirgacheffe coffee is particularly appreciated for pour over because of its complex flavor profile.
- Colombian green coffee: Ideal for those who want to roast coffee beans with a balanced flavor profile. Colombian beans often produce nutty and chocolatey notes with subtle fruit nuances when roasted.
- Kenyan green coffee: Roasting coffee beans from Kenya often results in a cup with bright acidity and complex flavor. These beans are known for their berry and citrus notes.
- Costa Rican green coffee: An excellent choice for those who want to roast coffee beans with a clean and balanced flavor. Roasted Costa Rican beans often produce chocolate and nut notes.
- Guatemalan green coffee: Roasting coffee beans from Guatemala can produce a complex cup with hints of chocolate, nuts and subtle fruit tones.
When choosing green coffee to roast coffee beans for pour over, look for:
- Fresh green coffee from the last harvest
- High quality green coffee (often labeled as “specialty grade”)
- Raw coffee grown at high altitude, which often produces more complex flavors when roasted
- Raw coffee processed to bring out natural flavors, such as washed or honey-processed coffee
Remember to experiment with different origins when roasting coffee beans. For example, try roasting Yirgacheffe coffee with different roasting profiles to find your perfect cup. The pour over method is great for bringing out the subtle flavors in carefully roasted green coffee, especially from complex origins like Yirgacheffe coffee.
By choosing the right green coffee and learning the art of roasting coffee beans, you can create an extraordinary pour over experience, whether you prefer the delicious Yirgacheffe coffee or other exciting origins.

This article explores the art of roasting green coffee beans specifically for espresso. It covers the differences between espresso and filter roasting, how roasting profiles affect flavor and aroma, as well as important factors that influence the outcome in the cup, such as origin, roasting time and the use of different coffee blends.
For light roasted coffees, a shorter development time is often recommended, usually around 15-20% of the total roasting time. This helps to preserve the coffee’s bright, fruity notes and lively acidity.
Different roasting methods can significantly affect the development time. For example, drum roasters tend to provide a more even heat distribution and thus more control over development time, while air roasters often have shorter overall roasting times and thus shorter development times. It is important to customize your approach based on the specific equipment you are using.
In general, coffees grown at higher altitudes tend to be denser and harder. This may require a slightly longer development time to fully develop the flavors. However, it is important to remember that each green coffee is unique and may require individual adaptation.
If you find that you have exceeded the optimal development time, it is best to stop roasting as soon as possible to avoid further over-roasting. Unfortunately, if the development time was too short, you cannot ‘go back’ and continue roasting. In both cases, it is best to learn from the experience and use the knowledge for the next roasting. Remember, even‘failed‘ roasts can provide valuable insights!
The development time actually has minimal impact on the caffeine content. Caffeine is relatively stable during the roasting process. What mainly affects the caffeine content is the choice of green coffee and the amount of coffee used in brewing.

Common mistakes include over- or under-roasting, uneven roasting, not cooling the beans quickly enough after roasting, and not taking into account the origin of the beans when choosing the roasting profile.
The degree of roasting affects the taste, aroma and body of the coffee. Lighter roasts tend to bring out the original character of the coffee, while darker roasts produce a stronger, more ‘roasted’ flavor
Roasting coffee in a popcorn machine is a simple home roasting method. Using a machine with side ventilation, roast small amounts at a time, paying attention to the first and second “crack” to achieve the desired degree of roasting.
Pour-over coffees often benefit from a light to medium roast to bring out the natural flavors and acidity of the coffee. Exact roasting can vary depending on the origin of the beans and personal taste.
Freshly roasted coffee should generally be rested for 24-72 hours to allow CO2 to dissipate and flavors to develop. Exact resting time may vary depending on the degree of roasting and the origin of the beans.
Specific coffee varieties and origins
Yirgacheffe coffees are often roasted light to medium to bring out their floral and fruity notes. Avoid dark roasting, which can hide the unique original character of the coffee.
