On gentle roast coffees specifically, our early xBloom efforts got here out a bit acidic and skinny after we used the default recipes that got here with the app—an indication the espresso was not being extracted nicely sufficient.
Was our preliminary underextracted espresso the results of Philadelphia’s semihard faucet water? Maybe.
Both means, we slowed down the pour by swapping out xBloom’s home filters to thick-papered Kalita filters, and in addition deviated sharply from the app’s prompt recipes. We elevated the pause occasions on every pour, and floor our beans a lot finer. As soon as we lastly bought it found out, the outcomes had been admirable.
However let’s say you don’t need to strive for days or perhaps weeks to determine your preferrred system. The xBloom presents a shortcut within the type of roast-to-order xPods ($13 to $24 for eight) accessible by mail order, typically from a few of the hypiest third-wave roasters in espresso. Your compostable pods will arrive with an RFID recipe card, preprogrammed and theoretically optimized to every bean. Simply swipe the cardboard, then push the button.
Outcomes will differ by roaster, as in life. A recipe for a single-origin bean from Indian-American espresso roaster Kaveri was dialed in fantastically, resulting in a cup brimming with chocolate and citrus. Not so with NBA participant Jimmy Butler III’s Bigface espresso model. That recipe, seemingly left on the machine’s default coarse grind, led to tart and woefully underextracted espresso.

The pods are additionally pricey, about $1.60 to $3 apiece. This makes this feature most tasty to folks with much less time than cash, or firms who’d like a powerful pour-over machine of their break room.
The folks we count on to be most excited concerning the xBloom are those that love expertise itself. The xBloom Studio is, fairly merely, cool. It is new and fascinating, and enjoyable to play with. And as soon as you work it out, the machine rewards you with scrumptious espresso.

For players or obsessive optimizers, the xBloom Studio presents infinite variables to toggle within the quest for the exactly dialed and repeatable pour-over. It’s a robotic that may do virtually all the be just right for you on the push of a button, and by no means get distracted whereas crusty-eyed and bleary from the wrestle of going through one more day.
As with every new expertise, count on some kinks: The identical inputs don’t at all times result in the identical outcomes. Typically the grinder piles up many of the beans on one aspect of the dripper, and the machine blithely pours water as if this didn’t occur. Different confounding variables embody altitude, water hardness, and the freshness of the espresso.
The machine additionally noticed some early glitches after its launch in June 2024, together with a “waiting” error attributable to the machine’s overflow safety algorithm; this has largely been resolved by successive firmware updates. A dripper arm additionally cracked throughout brewing and was rapidly changed with an up to date model.
Which is all to say, the dream of the always-perfect cup is just not but right here. However it’s shut sufficient to be tantalizing.
