Inconsistent extractions? Uneven saturation? Choked brews? The Bloom was designed to fix them all.
This next-generation brew bed preparation tool gives brewers total control over the coffee bed before the first drop of water hits.
In seconds, Bloom breaks up clumps, removes hidden air pockets, reduces static, lifts non-soluble materials like chaff, and shapes a perfectly bed for brewing.
Faster saturation, smoother flow, and more consistent cups, every time. Whether you brew in a café, at home, or on a competition stage, Bloom delivers clarity, control, and confidence in every brew.
Bloom features an innovative retractable design powered by a precision inner helix mechanism for smooth, controlled movement.
This also allows for quick switching between straight and fan needle modes, and allows the needles to be protected during transport and when not in use.
The fan needle setting provides a static lift – as you sweep the Fan Needles through the coffee bed, it lifts non-soluble materials like chaff to the surface.
This reduces ‘choking’ of the brew bed and creates more consistency in draw-down time and overall extraction.
Bloom’s specialised needles resist bending and glide smoothly through the grounds, naturally attracting fines and chaff for cleaner brews.
By rapidly reducing static after grinding, Bloom lifts chaff, redistributes fines, and releases hidden air pockets — enhancing aroma clarity, flavour expression, and cup texture.
The Bloom’s specialised needles are able to be swapped, replaced and reconfigured to any configuration of your liking.
Each Bloom comes with several spare needles, ensuring you’re able to replace any when needed.
The Bloom features the FlowTip, an expertly crafted tip for creating an indentation in your coffee bed after needling.
A unique feature of the Bloom, creating this indentation in your coffee brew bed provides a faster and more even saturation, as well as reduces bubbling and channeling between brews.
