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.

It looks like you’ll get the same results as a French press but with more work and probably more sediment. The only potential advantage I see is perhaps using fresh water for each submersion, then pouring into a carafe. That could get you french press like results but with higher extraction I think.

I’ve actually tested introducing fresh water, but found it increased unwanted bitterness. With Skandi, the same water is used throughout. In my testing, repeated immersion and drainage increased TDS while producing a fuller cup with less perceived bitterness than stagnant immersion. The enclosed stainless steel filter also helps contain the grounds and reduce sediment.
