A Cafetière operates by means of direct pressure on the coffee granules + water mixture contained within a glass vessel. A plunger is pressed straight down unto the mixture, until it reaches the bottom of the glass, leaving a mostly particle free filtered coffee infusion in the upper chamber.

It's a simple but very effective way of making coffee, but in its present form there is no method of agitating the water/coffee to make the infusion process more efficient.

Spiralating Cafetière introduces a new element to the apparatus to enhance the entire process. This new element is a corkscrew thread on the plunger shaft, and a corresponding receiver on the normally circular hole through which the shaft travels.

This results in the plunger's filter head rotating as it is pressed down on the coffee/water mix. This rotation is delivered via a couple of ribs on the face of the filter face. The net result is that the coffee grain/water mix is agitated by the downward spiraling action, effectively releasing more coffee flavour. Clearly a better cup of coffee in the making.

The most efficient way of "releasing more coffee flavor" is to grind the beans more finely. The more surface area the particles expose to water, the more (and faster) the flavor can be released into the water. So, grind the coffee beans into nanoscopic-sized powder particles. Then try to find a filter that can separate them from the water you add....

Centrifugation is the way to go.

Yes but why stop at nanoscopy? You could use ablation to scrape individual atoms from the surface of the bean.

I never drink anything with fewer than three atoms.

I never thought about how many atoms I'm drinking, ever. And that's when I still drank, if you get my drift.
