Australia-based coffee equipment company Nucleus Coffee Tools is introducing the Bloom, a device for preparing dry pourover and drip coffee beds before brewing.
Essentially a WDT tool built for pourover and drip coffee, the Bloom features needles extending from a handle that users can employ to stir and optimize ground coffee inside a filter before adding water.
The Bloom’s smooth, corrosion-resistant and anti-static needles redistribute fines and isolate chaff for cleaner brews less prone to clogging or channeling, according to Nucleus. The needles break down hidden air pockets, improving extraction consistency for greater clarity, texture and flavor.
Users can customize the number and position of needles in two modes: straight out for conical brew beds or flared outward for flat-bottom brew beds.
“The Bloom was designed first and foremost with filter brewing in mind, as that is where we have experienced the most inconsistency, brew to brew,” Jordan Montgomery, Nucleus’s head of European sales, told Daily Coffee News. “However, we’ve conducted extensive testing across a range of coffee grounds and preparation methods, including espresso, batch brewers and ground coffee by itself in a container.”
Montgomery said the testing showed “marked improvements” in aroma, flavor expression and clarity, roundness of acidity, and a lower tendency toward dryness compared with the same brews in each format.
At the closed end of the bullet-shaped device is the FlowTip indentation tool, used to burrow a divot in the bed’s center. The company says this improves bed-depth consistency for more even saturation and provides a more controlled exit for gas bubbles during the bloom phase.
The tool’s components are made of thermoplastic, aluminum and silicone. The needles are made from a proprietary material that mitigates static, according to the company.
Needles extend, retract and switch modes with a twist of the FlowTip. When closed, the Bloom is compact and pocket-safe for travel kits and kitchen drawers, suitable for homes, cafes or competitions.
“It was designed to be as lightweight as possible while still remaining strong and easily transportable,” said Montgomery.
For Nucleus, the Bloom rounds out a distribution-tool lineup alongside the espresso-focused NCD (Nucleus Coffee Distributor) and the motorized, vibrating NCD Pulse that came out last year.
Montgomery said the company continues to explore new technologies for ground coffee distribution,while also preparing some significant updates for its flagship Link sample roaster.
The Bloom will retail for approximately $39, including three extra needles. Global sales through distribution partners are expected to begin in December 2025.
