The right technique allows you to make great poured coffee with fewer beans

Physicists have discovered the technology that allows them to produce the perfect coffee with up to 10% less beans.
Climate change is making coffee production more difficult, and it is becoming more important to brew it in the most efficient way possible. Arnold Mattissen At the University of Pennsylvania.
“Coffee is becoming more difficult to grow, so that’s why coffee prices could increase over the next few years,” he says. “The idea for this study was to actually see if we could do anything by reducing the amount of coffee beans needed while maintaining the same amount of brewing.
Mathijssen and his colleagues focused on pouring coffee, slowly adding hot water to the corn-shaped paper filter site. Their advice can be summarized into some very simple tips. First, pour slowly. The longer the beans are soaked in the water inside the corn, the more extraction will occur.
But this works to some extent. If poured slowly, the lot is not fully confused. They settle at the bottom and start to actually reduce the amount of extraction. To combat this, the second hint is to pour from the height.
“Living up the kettle height gives you more energy essentially from gravity,” says Matigen. “Afterwards, all particles enter this kind of global circulation that is not normally obtained when poured from a lower height.”
Team experiments showed that raising the kettle to 50 centimeters of cone increased the strength of the coffee. However, Mathijssen warns that if poured too high, the water flow will begin to collapse, forming unconnected Glugs, causing the coffee corn circulation to be confused again. Needless to say, boiling water from too high can pose a risk of burns.
“Be rational,” says Mattigen. “First, try slowly. Then lift it up. [the kettle] Go as slowly as possible, but please don’t let it [the flow of water] “We’re goodbye,” he says. “That’s the strategy I follow.”
While this process is highly dependent on the type of coffee, the size of the site, the type of kettle used, and many other factors, researchers have found that the technique can lead to a 5% to 10% savings in the amount of coffee needed. Their experiments showed that the resulting brew had the same amount of dissolved solids, so it should be just as strong and flavorful.
