Vital and important scientific advance

 

Researchers have determined how to make a better pour-over coffee.

Meanwhile, the Trump administration is slashing funds for science in the United States.

At least this important advance has been published before the return of the Dark Ages.

The Perfect Pour-Over Coffee Has Fewer Beans, Say Researchers

" “What we recommend is making the pour height as high as possible, while still maintaining a laminar flow, where the jet doesn’t break up when it impacts the coffee grinds,” said author Ernest Park.

In particular, the group found the thick water jets typical of standard gooseneck kettles are ideal for achieving this necessary height and laminar flow. Strong — but focused — water jets create an avalanche in the coffee grounds. Displaced grounds recirculate as the water digs deeper into the coffee bed, allowing for better mixing between the water and the grounds, and thus, results in a stronger coffee with fewer beans. If the water jet is too thin, it cannot adequately create this interaction to achieve a desirable strength and sensory experience."
