Key Concepts
-
Understanding Component Characteristics:
-
Identify the flavor, acidity, body, and roast behavior of each individual origin in the blend.
-
Recognize which beans are more delicate, acidic, or chocolaty to determine how they interact in a blend.
-
Profiling for Harmony:
-
Roast each component to highlight its strengths without overpowering the others.
-
Adjust development time and roast levels to ensure components contribute their intended sensory attributes.
-
Sequential vs Parallel Roasting:
-
Sequential: Roast components separately and combine post-roast for precise flavor control.
-
Parallel: Roast blended green coffee; adjustments focus on harmonizing the green blend’s behavior.
-
Sensory Alignment:
-
Conduct cuppings of the blended roast to evaluate balance, sweetness, acidity, and body.
-
Identify any dominant or underrepresented flavors and adjust component roast profiles accordingly.
-
Iterative Adjustment:
-
Modify charge temperatures, RoR curves, or development times of specific components.
-
Track changes and repeat cuppings to confirm the blend achieves desired taste targets.
-
Documentation and Traceability:
-
Keep logs of component origins, roast profiles, and resulting flavor outcomes.
-
Use these records to replicate successful blends consistently.
Summary
Blend component alignment ensures that each coffee origin contributes appropriately to the overall flavor profile. Through careful individual profiling, cupping, and iterative adjustments, roasters can achieve balanced, repeatable blends that meet quality and sensory goals.
