As for the seller: when the unit was originally delivered the steam wand wasn't performing well. After following the typical trouble-shooting tips and conferring with the seller, we found the unit was simply unable to produce enough pressure to steam or properly brew. Within a week the seller had replaced the unit, and I'm happy to report it works perfectly. No matter the production value there is always a possibility of a defect here or there. The seller standing by the product and immediately replacing it to our satisfaction really sealed the deal for us. I highly recommend both this product and the seller from whom we purchased it."
Throughout the latter part of the 20th century, a number of inventors patented various coffeemaker designs using an automated form of the drip brew method. Subsequent designs have featured changes in heating elements, spray head, and brew-basket design, as well as the addition of timers and clocks for automatic-start, water filtration, filter and carafe design, and even built-in coffee grinding mechanisms.
An early variant technique, called a balance siphon, was to have the two chambers arranged side-by-side on a sort of scale-like device, with a counterweight attached opposite the initial (or heating) chamber. Once the near-boiling water was forced from the heating chamber into the brewing one, the counterweight was activated, causing a spring-loaded snuffer to come down over the flame, thus turning "off" the heat, and allowing the cooled water to return to the original chamber. In this way, a sort of primitive 'automatic' brewing method was achieved.
In 1901, Luigi Bezzera of Milan patented improvements to the machine. Bezzera was not an engineer, but a mechanic. He patented a number of improvements to the existing machine, the first of which was applied for on the 19th of December 1901. It was titled "Innovations in the machinery to prepare and immediately serve coffee beverage" (Patent No. 153/94, 61707, granted on the 5th of June 1902). In 1905 the patent was bought by Desiderio Pavoni who founded the La Pavoni company and began to produce the machine commercially (one a day) in a small workshop in Via Parini in Milan.
“My boyfriend is a gadget nerd, and he bought the Bonavita 1900TS drip for us — it’s turned out to be pretty great. We had been using Chemex, but it’s hard to be patient in the morning! If you take the time you’d spend waiting for a pour-over and actually weigh the beans, then this baby is unbeatable. It tastes almost the same as the Chemex.” — Sara Conklin, owner, Glasserie
“I like the Technivorm Moccamaster because, from a scientific standpoint, it creates the proper water temperature (and temperature consistency) for good extraction of flavor from the beans. That’s the problem with most cheap automatics — they’re inconsistent about temperature. It also has a shower-head design for good water dispersion and saturation of the grounds. It consistently tastes almost (almost, I stress) as good as a manual drip.” — Andrew Chou, engineer, General Motors
Caffè Espresso translates to “pressed-out coffee.” It’s what happens when you force hot water through finely ground coffee beans. This brewing method is challenging to master, as slight variations in pressure and temperature can produce an extremely unpalatable shot. As such, the best espresso machine is forgiving to first-time owners, it extracts rich flavor from its beans, and it offers a complex balance of sweet, sour, and bitter.
Our coffee machines are easy to use, and are designed with glass or thermal carafes and non-stick warming plates to keep your drip coffee warm long after the brewing process is over. Your coffee machine will alert you when it has finished brewing, and, depending on the model, will have either an automatic shut-off or a freshness indicator to ensure you never need to drink stale coffee again.
It’s not that cone filters won’t make a great cup of coffee — the OXO On 9-Cup still ranked fifth out of 10 in our taste test. But flat bottoms generally allow for the grounds to be more evenly extracted and increase the coffee’s flavor. (It’s no coincidence our other three recommendations have flat-bottom brew baskets). You may have to do a little more tweaking to get this coffee maker’s brew to the best it can be, and that’s the other reason we like the 12-cupper more. This smaller version doesn’t let you tinker with water temperature.
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.
