<ul><li>A study by University of Pennsylvania researchers reveals that the best pour-over coffee requires generating an avalanche effect in the coffee grains.</li><li>Pouring from a greater height while maintaining a laminar flow allows grounds to recirculate and improves the mixing of coffee grounds effectively.</li><li>The results indicate that the extraction of the coffee can be tuned by prolonging the mixing time with slower but more effective pours using avalanche dynamics.</li><li>Using the pour-over method based on this research not only improves the flavor and quality of coffee but can also help reduce the demand on coffee beans worldwide.</li></ul>
