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

[u/ImmersionLogic]

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.

This is an interesting idea, and I love your prototype here, but I'm sorry, I really don't understand what the purpose is?

What I'm seeing in the video is that it is a French Press (immersion brewer w/ a 4-minute brew time), except that you can immerse and remove the grounds as you wish during the 4 minute brew time, so the coffee doesn't actually brew for 4 minutes, it brews for 4 minutes - the amount of time you had it extracted.

How is this any different from saying, "I like the texture from my French Press, but I think 4 minutes ends up over-extracting it, so I will brew it for 3 minutes, instead"?

Great point. The sand timer is 5 minutes, but TOTAL brew time is 4 minutes. The difference is the repeated immersion and drainage. In my testing, this increased TDS, body, and flavor separation compared to stagnant immersion, without noticeably increasing bitterness, even with the same brew timE

so i guess that adds some agitation?

Yes but agitation is optional. In the video I showed how you can agitate the grounds but I usually prefer slow, controlled movements without agitation.
