Attendees at the Science Mill engaged in a captivating hands-on experience that delved into the science behind one of the world’s most beloved beverages. The workshop offered participants a rare glimpse into the precise engineering and chemistry involved in brewing the perfect cup of coffee. From the role of water temperature to grind size and extraction time, visitors examined how these factors affect flavor profiles and caffeine levels. Experts guided attendees through each step, allowing them to test various brewing methods including French press, pour-over, and espresso, highlighting how subtle adjustments can make a significant difference in taste.

The event also featured an interactive segment where participants could explore the molecular transformations that occur during roasting and brewing. Informative displays broke down topics such as:

  • Chemical reactions: Maillard reaction and caramelization
  • Physical variables: Water composition and heat conductivity
  • Extraction science: Solubility and flow rate impact
Brewing Method Optimal Water Temp (°F) Brewing Time Flavor Notes
Pour-Over 195 – 205 2 – 3 min Bright, clean, floral
French Press 200 – 205 4 – 5 min Rich, bold, full-bodied
Espresso 190 – 196 25 – 30 sec Intense, concentrated, smooth
