A team of mathematicians and environmental scientists has developed a formula to create the perfect espresso. Their research focuses on how different factors influence the brewing process, particularly the size and packing of coffee grounds, known as the puck. By using advanced imaging technology and simulations, they explored how water flows through various ground sizes, leading to a better understanding of flavor extraction.
• Researchers studied coffee grounds from Rwanda and Colombia, grinding them into 11 different sizes.
• They used X-ray computed micro-tomography to visualize the internal structures of the coffee samples.
• The study revealed how pore space connectivity and grain size affect water flow and flavor extraction.
• Their findings can help improve espresso machines by allowing for customized grind settings and better filtration.
This research is significant for the coffee industry as it provides a scientific basis for enhancing espresso-making equipment. By applying these formulas, manufacturers can create machines that produce more flavorful and consistent brews, ultimately elevating the coffee experience for consumers.
