I have a much simpler (and affordable) version of this rig, but I have to admit getting a little caffeinated jealousy over this lovely siphon coffee maker.
Recalling the coffee maker invented by Loeff of Berlin in the 1830s, this is the balancing siphon coffee brewer. An alcohol burner heats water inside the copper kettle to 212º F, causing it to pass through the pipette and into the lead crystal brewing chamber where it steeps the coffee grounds at the ideal temperature for making rich, complex coffee.
As water exits the kettle its integrated counterweight and hinge elevate the vessel, allowing the spring-loaded candle snuffer to cover and extinguish the alcohol burner’s flame. As the water begins to cool slightly in the brewing chamber, the internal pressure is lowered and a vacuum is created that draws the brewed coffee back to the kettle (the pipette’s filter removes coffee grounds) where it can be dispensed through the spigot.
The brewing chamber is made from 100% lead crystal, the candle snuffer, pipette, and spigot are made of brass, and the kettle is solid copper. Includes a mahogany base. Requires widely available denatured alcohol. 16″ H x 9 1/2″ W x 4 1/2″ D.
