‘siphon’ or ‘vac pot’ or ‘syphon’ is a vacuum coffee making instrument featuring two chambers, where the coffee is prepared through the combination of vapor pressure and vacuum. loeff invented this coffee making instrument in the 1830s at berlin in germany. this also happens to be my favourite city in the world, so we win on many counts here. siphon coffee makers have world-wide admiration for their capacity to brew a very refreshing beverage, but also have seen use in producing broths and cocktails by some of the world’s more adventurous chefs, due to it’s molecular mixing qualities.
siphon coffee makers are available in a range of designs, materials and compositions. they also occasionally present themselves as a creative outlet for depressed glass blowers.
siphon coffee brewing operates through the scientific principals of pressure and gravity. in the early siphons the water wass kept under hydrostatic pressure and due to this pressure, ummmm ….. oh who cares, it is basically a case of because science, and pressure differential, and removing of the environmental variables, and boom! exquisite coffee! give it a try, with a cleansed palate.
