The Chemistry of Coffee: From Bean to Cup

~60 min · 15 stations

The Chemistry of Coffee: From Bean to Cup is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify chemical components inside green coffee beans; analyze how water mineral content impacts extraction efficiency; examine how altitude affects bean density and sugar content.
