Applying fluid dynamics to pour-over coffee can help reduce bean usage while maintaining flavor. With coffee prices soaring due to climate change, researchers from the University of Pennsylvania have discovered a method to brew coffee using up to 10% fewer beans. Their study, published in Physics of Fluid, focused on optimizing the pour height and flow rate to enhance extraction efficiency.
• Coffee prices have reached record highs, surpassing $4.30 per pound.
• The study found that pouring from a height of 50 cm creates a stronger brew.
• Using a gooseneck kettle helps achieve the necessary flow and height.
• The technique allows for deeper water penetration into the coffee bed, recirculating grounds for better extraction.
This research is significant as it addresses rising coffee prices and the challenges of coffee production. By reducing bean consumption without sacrificing taste, it offers a practical solution for coffee lovers facing higher costs. This technique could help sustain coffee consumption amid environmental pressures.
