Example answer

“At my previous job, we faced a situation where our espresso roast was consistently coming out too bitter. Using the STAR method, I first analyzed the roast profiles and identified that the temperature was too high. I adjusted the roasting parameters and conducted several test batches to monitor the flavor. This not only improved the taste but also led to a new standard for our espresso blends, enhancing customer satisfaction significantly.”

Introduction

Understanding roasting profiles is crucial for a Bean Roaster, as it directly impacts the flavor, aroma, and overall quality of the coffee. This question evaluates your technical knowledge and experience in coffee roasting.

How to answer

• Define what roasting profiles are and their significance in coffee brewing.
• Discuss specific roasting profiles you have worked with and the flavor notes they produced.
• Share your process for developing or adjusting a roasting profile.
• Mention any tools or techniques you use to monitor and control the roasting process.
• Provide examples of how you have tested and refined profiles based on cupping results.

What not to say

• Avoid vague statements about roasting without specific examples.
• Do not claim to know all roasting profiles without acknowledging the learning process.
• Steering clear of the technical aspects of monitoring roast times and temperatures.
• Focusing solely on personal preference rather than objective taste testing.

Example answer

“In my previous role at Café do Mercado, I worked extensively with city and full city roasting profiles. For example, I found that a city roast brings out bright acidity and citrus notes, while a full city roast enhances chocolate and caramel flavors. I developed a new profile for a single-origin Ethiopian bean that emphasized fruity notes by adjusting the temperature ramp and extending the first crack. The feedback from cupping sessions confirmed the quality, leading to a 20% increase in sales for that bean.”
