Programmable coffee makers exist to make the brewing process as painless as possible. Outside of maybe grinding your coffee beans, the drip coffee system will use optimal water temperatures of around 205 degrees Fahrenheit or 96.11 degrees Celsius for maximum extraction of the ground coffee beans. The best automatic coffee maker will seamlessly reach this temperature within minutes of the brewing process.
CR’s take: If you’re an aficionado of fresh ground coffee, this Black+Decker is the brewer to buy. As the name suggests, the Mill & Brew goes that extra mile, grinding whole coffee beans just before brewing. As a result, the machine is capable of making a great pot of coffee. Made of plastic with stainless steel accents, this model is easy to use and to clean, earning a Very Good rating in our convenience tests. It allows you to adjust brew strength, and it’s programmable, so you can set it to grind and brew just before you wake up.
The Mr. Coffee Optimal Brew coffee maker System has a highly modular design, with its rectangular water reservoir easily sliding in and out of the chassis. For those who only want a cup of basic coffee, you will find that the Mr. Coffee Optimal Brew coffee maker System will do that very well – its "brew now" button is found on the front of the machine.
The gist: The Nespresso Inissia is very similar to the Pixie. It also comes with one-touch options for either a single espresso or lungo cup size. It pumps with 19 bars of pressure and also heats up in less than 25 seconds. With over 2,500 reviews, it stands out with a 4.4 star rating on Amazon. The Inissia has more or less the same internal workings as the Pixie (including the 0.7 liter water tank), so the quality of espresso produced should be pretty identical. The difference: unlike the Pixie, which is made of metal, the Inissia's exterior is mostly plastic and has a slightly funkier design. However the Inissia comes in several colors, including red, black, silver, and titan. 
‡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.

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.
“What I REALLY like about it is that it’s pretty much an all-in-one system without the thousand-dollar-plus all-in-one cost. I push one button and all the magic happens, and it’s quite entertaining to watch the espresso cascade through the milk and create separate layers. I also like that I can take the milk and store it in my fridge. I’ve done some temperature tests, and only noticed a five-degree increase after making a double latte, before I put it back in the fridge. This is nice, as you would think that to be so close to all that heat, it would be a much bigger temperature fluctuation.”

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.

The gist: Okay, so although most of our list focuses on countertop espresso makers, if we're going by Amazon reviews, it'd be an injustice to ignore this Bialetti Stovertop Espresso Maker. As Amazon's best-selling stovetop espresso maker, this classy little thing is POP-U-LAR. As in 6,950 reviews (and counting) popular. Most impressively, those reviews give it an average of 4.3 stars, with 74% of them giving it a perfect 5-star rating. That's a hell of a lot of happy people. Now, disclaimer: we do have to mention straight away that the Bialetti doesn't *technically* make espresso, considering it's not able to build the amount of bars of pressure necessary to again, *technically* qualify it as espresso. However, Bialetti does give tips and guidelines for how to brew their "moka" coffee to your liking. (Moka is described as a mix between coffee and espresso.) Also, some reviewers (see below for example) claim they can't even tell the difference between the moka and a shot of espresso.


For example, if your coffee tastes a bit salty or sour, the grounds are under-extracted, which can be remedied by a finer grind. But what if only some of your grounds are too coarse, and others are too fine – and maybe some are just right? Having uniform grind size throughout your brew basket makes it easier to isolate and adjust this variable in order to get the level of extraction you want. The only way to achieve that is with a burr grinder. Miller — as well as a handful of our other experts — recommends the Barazata Encore Coffee Grinder ($129).
If all you’re looking for is a gorgeous cup of coffee and no fuss, we strongly recommend the Bonavita BV1900TS. It’s the smallest machine among our top picks and, at $190, the cheapest. Even better, it ranked in the top three out of 10 during our taste tests. It’s also the simplest and most straightforward: one button you click to start brewing, and that’s it. You can’t program brew times; you can’t play around with water temperature; and it even lacks some convenient touches like a brew basket that attaches to the machine (when you’re done brewing, you have to place the brew basket on a plate or in the sink before it makes a total mess). But it’s by far the fastest machine out of our top picks, brewing up a full eight-cup pot in under six minutes. It’s a straightforward, high-end coffee maker that leaves little to complain about.
Thankfully we have Amazon, and moreover Amazon users (aka fellow espresso connoisseurs) who happen to be very vocal when it comes to their favorite machines. (We have read dozens of reviews and these folks are THOROUGH, to say the least.) To save you some time, we put together a list of the best espresso makers based on Amazon reviews. Our number one favorite was the Breville BES870XL. Not only does it take the spot of "best of the best" on Amazon's ranks page, its ease of use, freshness factor, and straight up *amazing* espresso-making capabilities have reviewers swooning. 
Why it's great: The Magnifica is the lazy espresso aficionado's dream device. It's basically the same thing as having your local coffee shop barista make your drink for you, only you don't have to leave your house or worry about them spelling your name wrong on your cup. Since it's a super-automatic, it pretty much takes care of everything, from tamping, to grinding, to extracting. The only thing you really have to do is fill the containers and push a few buttons. There are so many great features on this thing, with the reheat function being a customer favorite. And the fact that it's able to remember your favorite drink settings? *Chef's kiss.*
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.
