Although it's very easy to use — you just fill the portafilter with grounds, attach it to the machine, and press the button to start — The Gaggia Classic isn't as flexible or intuitive as the Breville Barista Express. The user manual is less detailed, too, so you have to have a basic idea of what you're doing or browse the internet for tips. The machine has a one-year warranty if you run into problems.
As a coffee nut, coffee-shop lover, and former professional barista, I don’t normally make recommendations for home espresso equipment. Not because I don't want you to have delicious espresso at home, but because it takes a lot of practice and a lot of burned fingers to learn to make espresso well. Many people invest in an espresso machine like they invest in the exercise equipment that becomes a very expensive coat rack: If you're going to buy it and never use it, you're almost always better off going to the local café.
Instead, our main concern was how well the wand incorporated air and steam into the mix for velvety, frothy texture. In our testing with our coffee expert, he pointed out that inferior steamer wands made giant air bubbles that quickly popped and only pumped air into the milk, without incorporating foam consistently throughout. So, we looked for a steamer wand that made consistent, well-incorporated foam.
The simplicity starts with its design: a single button with a scrolling dial underneath an LED interface. That button is the only one on the entire machine. With it, you set the time, set the water temperature, set how many cups you want brewed, and when you want the brewing to start. It takes a second to get the hang of it, but we were impressed with how intuitive it is — a stark contrast to a machine like the Moccamaster KBT 10-Cup Coffee Brewer, which had so many extra pieces, it required constant consultation of the instruction manual.
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.
