The 6 Best Coffee Maker in 2022
For coffee drinkers, the day doesn’t officially begin until their first sip of joe in the morning — and don’t you dare try to start it before then. A good coffee machine is essential for that morning pick-me-up, so you get a great cup every time. There are several variables that go into brewing the perfect cup: You need the water to be heated to a precise temperature range when it hits those coffee grounds, and the brewing process needs to happen within a specific window of time. Because of all this, it can be a daunting process to pick out the right machine. That’s why we’ve collected the very best coffee makers and compiled them for you below.
How we tested the coffee makers
Evaluating the performance of a coffee maker is trickier than it might sound. The first step is to know what good drip coffee actually is. According to the Specialty Coffee Association, there are criteria critical to brewing quality java. Mainly these are brewing time and water temperature. Hot water should come into contact with grounds for no fewer than 4 minutes and no more than eight. The ideal water temperature range is between 197 degrees Fahrenheit (92C) and 205 F (96C).
To see how well each coffee maker meets that challenge, we log the length of their brew cycles. We also employ thermocouple heat sensors connected to industrial-grade data loggers. That enables us to record the temperature within the coffee grounds while brewing is underway.
After brewing coffee, we take sample readings of the produced coffee liquid with an optical refractometer. Given that we factor in the amount of water and freshly ground coffee used, that data lets us calculate the Total Dissolved Solids percentage of each brew. From there we arrive at the extraction percentage. The ideal range is commonly thought to be between 18% and 20%.
We also back up measured data with a good old-fashioned taste test. If the taste of a cup of coffee is bitter, there’s a good chance it was overextracted during the drip. On the opposite end, an underextracted cup of coffee will typically taste weak — it can taste sour or have the flavor of soggy peanuts. And to be certain, we brew identical test runs a minimum of three times to get a sense of the average results.
