The New Coffee Syphons (also known as Vacuum Pots) are one of the best ways to brew coffee and produce a brew which is superior both in taste and quality to those of other brewing methods. First invented in the 1830s by Loeff in Berlin, coffee syphons have long been prized by connoisseurs for producing a clear brew. By using heat resistant glass, The new Syphons control the brewing temperature precisely between 91 to 95 degrees Celsius (196 to 2003 Fahrenheit) which is the ideal brewing temperature for coffee. This ensures the purity of flavor while avoiding the bitterness that results from boiling water.
