Coffee College: Everything You Wanted to Know about Coffee Making in One Lecture

Abstraction: Comprehensive 80-minute lecture on coffee extraction science by champion barista

Key points:

• Matt Perger, multiple barista championship winner and founder of Barista Hustle, delivered an 80-minute advanced coffee-making lecture at Assembly Coffee in London
• Covers flavor vocabulary from "weak" and "tea-like" to "bitter" and "overwhelming," then pivots to extraction chemistry
• Extraction—running hot water through grounds—is the most taste-critical stage; under-extraction yields salty/vegetal flavors, over-extraction yields astringent/powdery ones
• The ideal cup is "transparent," "nutty," "balanced," and "sweet"—achievable through careful calibration of roaster design, grind, and pour technique
• Perger cites experiments and blind taste tests, including cases where expensive gear showed no quantifiable benefit
• The lecture is the most-viewed video on the Barista Hustle YouTube channel
