This is an easy-to-use coffee maker that'll add some retro style to your countertop. It includes a pause-and-pour feature for times when you need caffeine before the brewing process is done — and after brewing, it keeps your coffee piping hot for 40 minutes (you can monitor the length of time on the indicator gauge on the front display). Available in black, cream, white and red.
On August 27, 1930, Inez H. Pierce of Chicago, Illinois filed patent for the first vacuum coffee maker that truly automated the vacuum brewing process, while eliminating the need for a stove top burner or liquid fuels. An electrically heated stove was incorporated into the design of the vacuum brewer. Water was heated in a recessed well, which reduced wait times and forced the hottest water into the reaction chamber. Once the process was complete, a thermostat using bi-metallic expansion principles shut off heat to the unit at the appropriate time. Pierce's invention was the first truly "automatic" vacuum coffee brewer, and was later incorporated in the Farberware Coffee Robot.
In the semi-automatic machine, water pressure and temperature must be stable and consistent, and according to our expert, the pressure shouldn't be too high. Typically, coffee is brewed at a pressure of about 10 bars, and an ideal water temperature is around 195 degrees. Generally, the more expensive the machine, the better the equipment inside that regulates these two factors. High-quality machines tend to have a mechanism called a PID, or proportional-integral-derivative, controller. The PID's function is to maintain constant water temperature with extreme accuracy, down to the degree. Two central problems plaguing inexpensive espresso machines is that they lack a PID, meaning the temperature of the brewing water can fluctuate up and down and yield inconsistent results. Inexpensive machines often advertise that they have 15 or 20 bars of pressure as a selling point. But, higher pressure is not the priority, and too much pressure can actually lead to over-extraction and bitterness in your espresso shot. Therefore, we looked for a machine with good temperature and pressure control.
Semi-automatic espresso machines are just that—semi-automatic. Some of the steps are automated, but many are not. This allows the user to put their personal stamp on the final product but without doing some of the tedious steps that are involved in making an espresso on the stove top. Here’s a look at some of the features that make a semi-automatic espresso machine such a great pickup for the ultimate espresso lover:
"My absolute love of the Delonghi Maginfica ESAM3300 is hard to describe. It has been a faithful crema steeped friend and morning ritual for at least 8 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 "super automatic" espresso dream machine a SOLID 5 star rating.
I have to say that I'm very happy that I waited for this one! The espresso is excellent, the drinks have all been hot (even when adding milk from the Aeroccino), the whole spinning process takes about 15 seconds (or less) to pour into the cup, and - most surprisingly - the new coffee-sized cartridges are AWESOME! They taste NOTHING like regular, ground grocery-store coffee-in-a-can. They are much more flavorful, much stronger, and seem fresher even than using whole coffee with a grinder (maybe it's from being sealed in the aluminum cartridges?)."

There’s also no way to adjust the temperature of the water on the Bonavita, or tinker with any of the other variables some of our other top picks gave access to. And that’s the other downside to this excellent machine: What you get is what you get, and if you do want to experiment with the flavor of your coffee, it will depend entirely on the beans you buy and the size you grind them to. Good thing the coffee it brews right out of the box is so dang good.
“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).”
Thank you for this great review. For me, I use Bonavita BV1900TS for about a year and I can say that it is Perfect. It’s equipped with most features that are desirable for home brewing. With this coffee maker, you won’t enjoy high-end functionalities, but you will prepare great coffee every time. The black and stainless finish makes it appear beautiful in your kitchen. The stainless steel lining extends the durability of the machine.
For many of us, the daily grind can't begin until we've had that first cup of piping hot coffee—so the right brewer is at the top of the list. The most basic coffee makers make at least a decent cup, but a little more money buys conveniences such as programmability, a thermal carafe to keep coffee hot longer, settings that let you adjust brew strength, and more.
