Timelapse (15x realtime) of brewing coffee using a Yama vacuum brewer (also called a vacuum pot or coffee siphon/syphon).

I step in to stir it three times, with a brewing time of about 3 minutes. I don't know how much stirring is actually necessary, but I'm sure too much can't hurt.

Compared to other brewing methods, this is far less practical and convenient. But the coffee it makes is absolutely incredible. Imagine a French press that could use fine grounds, brew at near-boiling temperatures the entire time, extract FAR more flavor, and leave zero sediment in the cup.

(There's no audio because screw Final Cut, I did this with ffmpeg.)
