On mild roast coffees particularly, our early xBloom efforts got here out a bit acidic and skinny once 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 approach, 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 advised recipes. We elevated the pause instances on every pour, and floor our beans a lot finer. As soon as we lastly bought it found out, the outcomes have been admirable.
However let’s say you don’t wish to attempt for days or perhaps weeks to determine your very best system. The xBloom presents a shortcut within the type of roast-to-order xPods ($13 to $24 for eight) accessible by mail order, usually from a number 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 system of their break room.
The folks we count on to be most excited concerning the xBloom are those that love know-how 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 limitless variables to toggle within the quest for the exactly dialed and repeatable pour-over. It’s a robotic that may do virtually the entire be just right for you on the push of a button, and by no means get distracted whereas crusty-eyed and bleary from the battle of going through yet one more day.
As with all new know-how, count on some kinks: The identical inputs don’t all the time result in the identical outcomes. Typically the grinder piles up a lot of the beans on one facet 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 “ready” error attributable to the system’s overflow safety algorithm; this has principally 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. Nevertheless it’s shut sufficient to be tantalizing.
