Listen "Lumber Grades and Great Coffee: How a 2x4 Explains Specialty Coffee"

Episode Synopsis


Join Don Cox as he revisits the question: "What is quality in coffee?" by introducing the Lumber Analogy. We break down why the score system—even for high-value Specialty Coffee—is, at its core, a Structural Inspection. We explore Commodity Coffee (70-79 points) as "Grade 3 lumber" riddled with Defects. The 88 Poins of a Kenyan AA I am considering for the holidays guarantee a flawless structure, but Subjective Pleasure dictates the final decision. Discover why your palate matters more than the label, and how the Objective Quality score ultimately validates your personal taste. Find out what the "rare air" 88-point Kenyan AA tastes like and how to get your hands on a bag.

5 Takeaways 

The Score is Structural, Not Aesthetic: The Q Grader system and the high scores (80+ points) primarily function as a Structural Inspection to guarantee the absence of defects (like a 2x4 with no crook or shake), not that you will prefer the flavor.
Commodity Coffee is "Grade 3 Lumber": Coffee scoring 70–79 points is deemed commodity coffee because it contains defects that impact flavor and structural integrity, resulting in a less complex, "blah" flavor profile.
Find Your "Species": Specialty coffee flavor profiles are like different wood species (Black Walnut vs. Spalted Maple)—all are structurally flawless (Grade 1 lumber), but your pleasure dictates which species (flavor) you prefer.
The Score Validates Your Pleasure: The score doesn't dictate that you must like a coffee; it simply confirms that the pleasure you find in a high-scoring cup is structurally sound and not accidental.
Q Grader Language is Descriptive: High-level terms like Acidity, Body, and Balance are the "highest vocabulary" used to describe the coffee's unique species and beauty, not to judge your personal taste.
