The secret to making stronger coffee using fewer beans: it's all in the physics

Want a more intense coffee without using more grounds? A recent study from the University of Pennsylvania reveals that the key lies in how you pour the water in your pour-over method.

What did scientists discover?

Researchers found that pouring water from a greater height and maintaining a constant (laminar) flow improved the extraction of coffee compounds. This method allows for a stronger beverage using less ground coffee.

Using a gooseneck kettle, which provides a thicker, more controlled stream of water, allows for better mixing of the grounds, especially at the bottom of the filter. This results in a more robust flavor without the need to add more coffee.

Sustainable benefits

In addition to improving flavor, this technique promotes sustainability by reducing coffee bean consumption, which is especially important given that coffee farming faces challenges due to climate change.

How to apply it at home?

• Pouring height: Pour water from the greatest possible height without the stream breaking into drops.
• Constant flow: Maintain a constant and controlled flow of water.
• Recommended Tool: Use a gooseneck kettle for better pour control.

This approach not only improves your daily cup of coffee, but also contributes to more conscious and sustainable consumption.
