I’ve been geeking out over coffee since yesterday, which is fun. The coolest thing I’ve been finding out about is vacuum-brewing or siphon- (also spelled “syphon-“) brewing. There are a lot of bad videos of the process in action. In this one, Chris Owens, a barista at Intelligentsia in Venice, California, demonstrates the process, which, you have to admit, has a pleasing mad-scientist aura about it.
