The journey of a coffee bean from a green seed to a flavorful beverage is complex, but no single step is more transformative than roasting. The roast level dictates the final flavor, body, and acidity of your coffee.
Understanding the roast spectrum is key to choosing the perfect Itadi Coffee for your palate and brewing method.
1. The Roasting Process: A Chemical Transformation
Roasting is essentially a controlled chemical process that involves heat, time, and airflow. As the temperature rises, the beans undergo the Maillard reaction (browning) and caramelization (sugar breakdown), which create hundreds of new flavor compounds.
•Lighter Roasts: Shorter time, lower temperature. Retain more of the bean's original acidity and origin characteristics.
•Darker Roasts: Longer time, higher temperature. Develop more bittersweet, chocolatey, and smoky flavors, while reducing acidity.

3. The Itadi Coffee Roast Profile
While Arabica is often roasted light to preserve its delicate acidity, Itadi Coffee (Robusta) is best suited for a Medium to Medium-Dark Roast.
•Medium Roast: This is the sweet spot for our Togolese Robusta. It develops the natural dark chocolate and nutty notes while maintaining a pleasant sweetness and a full, syrupy body. This roast is versatile for both filter and espresso.
•Dark Roast: Robusta holds up exceptionally well to a dark roast. The natural intensity and low acidity of the bean mean it can be roasted dark to create a powerful, smoky, and bittersweet cup that is perfect for traditional espresso or milk-based drinks.
4. Choosing Your Roast
•For Clarity and Sweetness: Choose a medium roast to enjoy the balanced complexity of Itadi Coffee.
•For Intensity and Body: Choose a medium-dark or dark roast for a powerful, traditional espresso experience with maximum body and crema.
The roast is the final signature on the bean's journey. By understanding how the roast level affects flavor, you can make an informed choice and ensure that your brewing method perfectly complements the profile of your chosen Itadi Coffee.
