If you’re shopping for coffee at the grocery store, “check the roast date, rather than the ‘best by’ date,” says Awan. With mass market roasters, the “best by” date can obfuscate the window in which coffee beans are at their best: about 4 days after roasting, when some, but not all, of the carbon dioxide has escaped from the beans. (Too much carbon dioxide captured within beans tends to create uneven extraction, as the gas escapes — this is what pre-infusing tries to counter. Conversely, too little carbon dioxide in the bean can lead to a loss of flavor.)
It scored the highest in our out-of-the-box taste test, brewing coffee our tasters described as “light” with subtle notes of blueberry, citrus, cherry, tobacco, and hazelnut. The machine simply brews great coffee, and it takes its job seriously. If you’re interested in playing around with the flavor and extraction of your roast, the Behmor Brazen gives you more access to more variables. You can adjust water temperature, play with pre-infusion times (15 seconds to four minutes) — it even has you enter your altitude to better determine water’s boiling point, and calibrate its internal thermometer during setup.
