CoffeeKid - The Vacuum Brewer FAQ (#)
„A still less common type is the Napier vacuum brewer, which is a one way only vacuum brewing device. It looks similar to a balance brewer, except that you add most of your pre-boiled water to the brewing side with the coffee grounds, only a small amount of boiled water to the kettle side, and apply heat. The heat expands the water vapors in the kettle, pushing steam through a siphon tube which agitates your pre-mixed slurry. Once the heat is removed, a vacuum is formed and it pulls your brewed coffee over to the kettle portion.“

„Brewing has challenges - if you don't use the machine frequently, you have temperature issues with the brew head. But you get amazing thermal stability on a well used machine because its a boiler full of brewing water, not just a heat exchanger which can fluctuate.“

CoffeeKid - Press Pots and Drip Brewers
„I had the head technical troubleshooter at Saeco USA once tell me that coffee is "supposed to be brewed at 165F" when he was contacted about complaints that the Saeco Latte was brewing too cold. And once, I wrote Braun enquiring why their machines never seem to produce temperatures hotter than 180F at the showerhead (in the carafe, the coffee is closer to 175F), and they told me that their extensive scientific study has "proven" that 175F to 180F is the optimum brewing temperatures.“

CoffeeKid - The Espresso MiniFAQ
„When you tamp with 20lbs or less pressure, you're increasing the chances of a phenomenon called "channeling". Water always seeks the path of lease resistance, and when you tamp light, or don't tamp at all, you run the risk of portions of your lose grounds compacting quicker than others, and water will go through the parts of the coffee that are the least compacted.“
