Coffee Experiment

Nearly 7 months later, I've finally captured our new vacuum-action chemistry--err, coffee process on camera.

The apparatus, pre-assembly:


Assembled, coffee and water in place:


As the water heats, vacuum action sucks it up the tube into the globe, where the coffee awaits:


When the water in bottom begins to boil, the steam pressure agitates the coffee, eliciting the perfect brew:


With a centimeter or two of water remaining in the bottom, the entire assemblage is gently removed from the heat, releasing the suction in seconds as it cools:


The now-brewed coffee drains back into the bottom, leaving the grounds on top:


Detach and enjoy!

Wow, your friend Lotto seems really nice! What is he . . . Swedish?

Anyway, I was always curious about how those worked. I assume the filter is permanent?

Ummm. . .friend. Right. A loose term, sometimes. ;-)

Yes, the filter is permanent.

I've always wanted one of those. How does the coffee taste compared to a french press?

Hope you guys are doing well.
