Coffee Bean Roasting Around the World: A Global Journey of Flavour and Tradition

Coffee roasting is more than a culinary technique—it’s a cultural art form that reflects history, geography, and taste preferences. From Ethiopia’s ceremonial light roasts to Italy’s bold espresso blends, roasting styles tell stories of tradition and innovation. Let’s dive deeper into global roasting practices and learn how you can bring this craft home.

Home Roasting Tips: Bring the Craft to Your Kitchen

Roasting coffee at home is rewarding and surprisingly accessible. Here’s how to start:

1. Choose Your Beans

• Start with high-quality green beans. Ethiopian beans for fruity notes, Brazilian for chocolatey richness, or Sumatran for bold earthiness.

2. Select Your Method

• Stovetop Pan: Traditional and inexpensive. Stir constantly for even roasting.

• Popcorn Popper: A popular DIY method for beginners.

• Home Roaster Machine: Offers precise temperature control for consistent results.

3. Understand Roast Levels

• Light Roast (City): Bright acidity, origin flavours intact.

• Medium Roast (Full City): Balanced sweetness and body.

• Dark Roast (French/Italian): Bold, smoky, bittersweet notes.

4. Monitor Temperature

• Light roast: ~195°C (383°F)

• Medium roast: ~210°C (410°F)

• Dark roast: ~225°C (437°F)

5. Cool Quickly

Once beans reach your desired roast, cool them fast to stop the process. Use a metal colander and fan for airflow.

6. Rest Before Brewing

Allow beans to degas for 12–24 hours for optimal flavour.

Pro Tips

• Keep a roasting log: Note bean origin, roast time, and flavour profile.

• Ventilate your space: Roasting produces smoke and chaff.

• Experiment: Try blending beans from different regions for unique flavour combinations.

Africa: The Birthplace of Coffee

• Ethiopia: Coffee ceremonies are central to Ethiopian culture. Beans are roasted over an open flame on a flat pan, producing light roasts that preserve fruity and floral notes like jasmine and citrus.

• Kenya & Tanzania: High-altitude beans with bright acidity are often roasted lightly to maintain wine-like flavours and vibrant complexity.

Central & South America: Balanced and Sweet

• Guatemala & Costa Rica: Medium roasts dominate here, unlocking chocolate and citrus notes. These beans thrive at 410–428°F for a balanced cup.

• Brazil: Known for nutty, caramel flavours, Brazilian beans often lean toward medium-dark roasts, perfect for espresso blends.

Asia-Pacific: Bold and Earthy

• Indonesia: Sumatran beans are roasted dark to highlight earthy, spicy undertones and a syrupy body.

• Japan: Precision defines Japanese roasting, favouring medium roasts for nuanced sweetness and acidity.

Middle East: Tradition Meets Ritual

• Turkey & Yemen: Turkish coffee uses finely ground beans roasted medium-dark for intense flavour. Yemen’s beans require gentle roasting to preserve wild fruit notes.

Europe: The Art of Dark Roasts

• Italy: Espresso culture thrives on dark roasts, producing bittersweet, caramelized flavours ideal for concentrated brews.

Modern Innovations

Today’s roasters use computer-controlled machines and fluid-bed technology for precision and consistency. These methods allow roasters to highlight unique flavour notes while improving sustainability through energy efficiency.
