Pierce's design was later improved by U.S. appliance engineers Ivar Jepson, Ludvik Koci, and Eric Bylund of Sunbeam in the late 1930s. They altered the heating chamber and eliminated the recessed well which was hard to clean. They also made several improvements to the filtering mechanism. Their improved design of plated metals, styled by industrial designer Alfonso Iannelli, became the famous Sunbeam Coffeemaster line of automated vacuum coffee makers (Models C-20, C-30, C40, and C-50). The Coffeemaster vacuum brewer was sold in large numbers in the United States during the years immediately following World War I.
All the machines we tested came with either insulated carafes or glass pots with built-in warmers. Both have pros and cons. Glass pots are typically easier to clean because they tend to have wider mouths, and the lack of internal insulation means that glass pots will have a greater interior volume relative to its exterior volume — basically, it’s easier to get your hand or dish sponge into a glass pot. On the other hand, glass pots are more fragile and have to be heated from a base plate. In our tests, those base plates could even raise the temperature of the coffee, like with the CuisinArt, which can make coffee taste burnt.
"Having worked in a coffee shop I was familiar with espresso and milk steaming machines. While this product is not intended for commercial use, it is perfect for the home. The machine itself has an amazingly small footprint, and puts out adequate pressure for brewing single/double espresso shots and for properly steaming milk. The inclusion of different sized "inserts" which allow switching depth of the coffee filter attachment is a novel idea and well executed. Bought this item as a gift for my wife who loves it, but I use it myself frequently as well. Keep it clean and it should serve you for an extended period of time. For the price, I don't believe this item can be beat.
A cafetiere (Coffee Plunger, French press in US English) requires coffee of a coarser grind than does a drip brew coffee filter, as finer grounds will seep through the press filter and into the coffee. Coffee is brewed by placing the coffee and water together, stirring it and leaving to brew for a few minutes, then pressing the plunger to trap the coffee grounds at the bottom of the beaker.
From there, it’s up to your personal preference. Arabica beans have a higher acidity, with notes of fruit and berries. Robusta beans are darker and richer, with more caffeine. Different levels of roasts — light, medium, dark — determine how much of the beans’ oils will break through the surface of the bean, which also affects acidity, flavor, and caffeine levels. “Get to know your local coffee expert,” recommends Awan. Nothing beats a conversation with a barista or local coffee roaster who can help you try different beans and roasts, and to experiment with those variables in real time. Finding your favorite is all part of the fun.
‡Pre-Infusing: Pre-infusing is a technique where the dry coffee grounds are initially saturated with hot water, allowing a “bloom” of carbon dioxide to escape. This 45-second(ish) process puts hot water into contact with more surface area around each ground throughout the brewing process, as it’s no longer competing with the escaping gas bubbles. It can improve the quality of the final product, since this more uniform contact creates a more even extraction. It’s a feature that six of the 10 pots we tested incorporated into their designs — as well as all four of our top picks.
“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
Tamp: To ensure the espresso is evenly packed, your machine comes with a tamp, which you’ll press into the basket against the grounds. This step is important: When you pull a shot, the water will go to the place of least resistance, avoiding densely packed areas. This denser espresso won’t be properly saturated, making it under-extracted and sour, while the looser espresso will be over-extracted and bitter.
If your busy life keeps you from making coffee by hand, you can also consider a capsule machine such as a Nespresso coffee maker. These machines use small capsules or pods of coffee, so you don’t have to worry about measuring grounds and adding them to your device. Simply add a capsule, fill up the reservoir and press the On button. If you’re more of a traditionalist, a stovetop espresso maker might be the right option for you. This type of maker uses your stove to heat up water, which then steams up and passes through a capsule of grounds above the reservoir. The steamy espresso then collects in an upper reservoir at the top of the maker. These espresso makers are very popular in Europe and require no electricity to function.
If you're highly particular about how your coffee tastes, you'll want the Behmor Brazen Plus. It was the only drip machine we tested that brewed at the optimal temperature to bring out the best flavor from coffee beans. Getting this perfect brew takes a little more time to set up than most coffee makers require— before starting, you have to calibrate it for the altitude in your area— but overall it's easy to use.
This coffee maker is excellent. How could it not be? Its SCAA-certified, and the technology is practically identical to the 12-Cup brewing system. Lots of what we love about the 12-Cup, from its single-dial programmability to its auto-pause brewing to its multi-port shower head, is pretty much the same. Plus, it brews eight cups in a much swifter nine minutes, and is $100 cheaper.
Because the coffee grounds remain in direct contact with the brewing water and the grounds are filtered from the water via a mesh instead of a paper filter, coffee brewed with the cafetiere captures more of the coffee's flavour and essential oils, which would become trapped in a traditional drip brew machine's paper filters. As with drip-brewed coffee, cafetiere coffee can be brewed to any strength by adjusting the amount of ground coffee which is brewed. If the used grounds remain in the drink after brewing, French pressed coffee left to stand can become "bitter", though this is an effect that many users of cafetiere consider beneficial. For a 1⁄2-litre (0.11 imp gal; 0.13 US gal) cafetiere, the contents are considered spoiled, by some reports, after around 20 minutes. Other approaches consider a brew period that may extend to hours as a method of superior production.
"Put off buying a Keurig type machine for years because it didn't seem their coffee was that much better than what I could make for the money. Went out of the country and was staying in a 5 star hotel where they had this little miracle machine in the room with some of the coffee capsules. We were at a retreat where sometimes we had to meet at the beach at 6 a.m. It was so fantastic to be able to make the most incredible, luxurious, espresso I've ever had in my life (and I've had a lot of bad espresso). It takes very little time and is super easy to use. There are fantastic "how to" videos about the machine on youtube that I checked out when it arrived. It's small, sleek and makes seriously incredibly fantastic espresso and lungo (which is a larger version of espresso). Loved that the amazon price was like $90 less than anywhere else online too! The vendor I purchaesd it from sent the wrong color by mistake but we were able to send the original back unopened and they sent a replacement out immediately. Absolutely recommended item if you love coffee and want a special treat at home."
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.
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."
Whole bean coffee that you grind yourself is preferable to pre-ground, too. The bean’s exterior traps and protects all of the delicate, volatile, and water-soluble oils that give coffee its flavor. As soon as you break the protective shell, it’s easy for the flavor to get contaminated, and much of the aroma escapes as soon as the oils are exposed to air.
That said, it’s not as elegant to use as the OXO machines. (Nor is it as nice to look at. One tester described its tall, bulbous body and squat carafe as “UFO-like.”) Take its eight-button controls, for example, which you use to toggle among brew modes, scroll up and down within the menu, and engage a manual brewing feature. Programming it to start brewing at a certain time was about as intuitive as setting an alarm on a clock radio — easy enough, but more technical than sleek. OXO definitely feels like the future; Behmor is more, “If it ain’t broke, why fix it?”
The Breville Barista Express comes with everything you need to pull great espresso. A built-in grinder lets you adjust grind coarseness, and changing the amount of ground coffee that you want in your shot is easy: Simply turn a dial or press the portafilter firmly against the dispensing cradle. A button at the back allows you to dose as much or as little coffee as you wish.
When it comes to features, our top pick’s little sister, the OXO On 9-Cup Coffee Maker, looks and feels much the same: a single-button dial, programmable start times — even the timer that lets you know how old the coffee is after it’s been brewed is identical. On this version, the water reservoir isn’t detachable, but it brews coffee significantly faster than the 12-cupper’s 14 minutes(!) and it’s $100 cheaper. It’s a great machine that didn’t earn our top spot simply because the coffee it makes didn’t perform quite as well as the other three top picks in our taste tests, and it doesn’t let you tinker with water temperature and extraction the way the larger machine does.
While we love the all-inclusive features of the Breville, there’s one thing it can’t do on its own, at least not without a hefty repair bill. If you love dark roasts, any machine that features an internal grinder is off-limits. The oily shine characteristic of dark roasts builds up in any grinder — but while you can disassemble and clean standalone grinders, this is rarely an option for internal ones. The residual oil left in an internal grinder will, at best, give future shots a rancid flavor. At worst, the oil will clog the grinder. If you want to brew dark roasts on the Breville, plan on buying a separate grinder.
Picking up a bag of coffee beans from the roaster is a great way to make sure you have fresh beans. Because coffee gets damaged as it’s exposed to air, espresso connoisseurs recommend using beans within two weeks of their roast date. But you won’t want to use them the same day that they’ve been roasted — they need a few days to de-gas from the roasting process.
