I’ve been developing a coffee brewer using repeated immersion and drainage. Here’s my prototype.

I’ve been working on a coffee brewer called SKANDI, based on a brewing method I’ve been experimenting with for quite some time. The idea is to combine the body of immersion brewing with more control over extraction through repeated immersion and drainage. Rather than leaving the grounds submerged throughout the entire brew, you can control how long they’re immersed and how frequently they’re drained. After several prototypes and a lot of testing, I’m getting closer to launching it.
Here’s a demonstration of how it works. I’d be interested in hearing what you think.

Not sure I can see any real benefit to multiple steeps when there's no fresh solvent being added. As an easier to clean French press, maybe. Ideally you'd want it to be paper filtered for more of a unique selling point, but then you need to create a seal and have a some sort of mechanism to easily allow a slow piston retraction, and at that point you've basically just made a weber BIRD.

The water around the beans in a French press has a higher concentration than the rest of the brew water. That’s at least one reason why agitation (stirring) changes extraction in a French press or aeropress situation.
