This Yama glass stovetop Coffee Syphon is a unique kind of brewer. Akin to something in a scientific laboratory, the Vacuum style brewer is as much a conversation piece as it is a quality Coffee brewer. The Yama glass siphon brewer ships with one filter cloth, the filter assembly, a measuring spoon, the lid/stand, and the brewer itself. The 8 cup size specification refers to the Yama cup size, which measures to about 3-4 ounces per cup. Warning: use extreme caution when heating with an open flame directions for use: use a slightly finer grind of Coffee than used for auto drip, however you may experiment to taste. Drop the washable, reusable cloth covered filter into the infusion chamber with the chain hanging down into the glass Syphon tube. Pull the chain down until you can hook it to the bottom of the siphon tube. Fill the bottom carafe to the 8 cup mark with hot water and place 8 measuring spoons of Coffee mark in top chamber. Using the wire trivet between the Coffee siphon and the burner place the Coffee siphon on the burner and turn on to medium heat. Do not turn the burner on high as the water boils, it will be siphoned up to the top chamber where it will infuse with the ground Coffee. A little water will always remain in the bottom water chamber. Let brew about 60 seconds, then remove the pot from the heat source. Once the Coffee starts to cool the liquid is siphoned back down into the bottom carafe. Remove the top, placing it in its convertible lid/stand, and bring the pot to the table for serving. Gently Rock the upper carafe back and forth until it can easily be removed and placed into it's stand. Serve and enjoy your fresh great tasting Coffee.
