Other coffee brewing devices became popular throughout the nineteenth century, including various machines using the vacuum principle. The Napier Vacuum Machine, invented in 1840, was an early example of this type. While generally too complex for everyday use, vacuum devices were prized for producing a clear brew, and were popular up until the middle of the twentieth century.
“My absolute love of the DeLonghi Magnifica ESAM3300 is hard to describe. It has been a faithful, crema-steeped friend and morning ritual for at least eight years, and the current unit I bought as a replacement last week (another ESAM3300) is a testament to why I give this well-built Italian stallion and ‘super automatic’ espresso dream machine a SOLID five-star rating. With very few adjustments and some good Italian or locally roasted whole beans, the Magnifica consistently puts out shot after shot of delicious espresso that will FAR exceed anything you could get at most coffee shops. I always use many of the yummy Lavazza beans, including the Super Crema, Gold Selection, and others that work really well with this machine. The Illy beans are also a nice pairing for this superb machine. The key is, you want nonoily and fairly dry beans (as other reviewers have said here already).”

Our brew-performance tests measure the brew temperature and contact time (how long water stays within a sweet spot of 195° to 205° F for brewing). We measure concentration using a refractometer, a device that measures the amount of coffee dissolved in each brew. Our convenience tests look at how easy it is to set timers, fill the reservoir, clean the machine, and more. And for the first time, we’re incorporating predicted reliability and owner satisfaction ratings into the new Overall Score for each model. We determine these ratings for each drip coffee maker brand using survey data collected from thousands of CR members.
