Physics can help you brew better coffee with fewer beans
- Climate change is impacting coffee crops globally, leading to rising Arabica bean prices due to poor weather conditions.
- Researchers at the University of Pennsylvania are using physics to enhance coffee brewing and reduce bean usage.
- Their study in Physics of Fluids uncovers the physics behind coffee brewing, focusing on flavor extraction.
- By studying fluid dynamics and mechanics in coffee brewing, researchers discovered the 'avalanche effect' that enhances flavor extraction.
- Pouring water from a controlled height and speed improves mixing and extraction efficiency without compromising flavor.
- Using precise measurements and equipment like gooseneck kettles optimizes water flow for better coffee extraction.
- The findings not only apply to coffee brewing but also have broader implications for understanding fluid dynamics in nature and industry.
- Research into coffee brewing can lead to insights in applications like medical device cleaning and biological fluid movement studies.
- Adjusting pouring techniques with a gooseneck kettle can reduce coffee bean usage while maintaining taste and strength.
- Improving sustainability in coffee production by maximizing flavor extraction per bean is vital amid environmental challenges.
