The Florence Siphon. The vacuum siphon coffee brewing method dates back to the 1840s.

The Florence Siphon

It produces some of the cleanest, smoothest-tasting coffee of any method. Commercial vacuum pots are available, but I wanted to heighten the drama of vacuum brewing by taking it into the realm of the mad scientist’s lab. Thus the Florence Siphon was born! After studying original patent drawings and existing devices, I identified these key features: Water is heated in a boiling flask that has a tube leading to a second vessel containing ground coffee.The tube must have a filter, to allow the water to flow through but not the grounds. One drawback to early vacuum brewers was the constant danger of exploding glass. Filtration was another challenge. I assembled my funnel, stopper, tubing, filter, and a beaker for the grounds. The water began to bubble quickly, and soon went straight up the glass tube and over to the grounds. I stirred up the slurry with a stick and then waited with great excitement.
