Nucleus Bloom

Are you looking to buy Nucleus Bloom in Australia?

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 chaff, and shapes a perfectly even surface.

Faster saturation, smoother flow

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.

Retractable design

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.

Straight needles

The dual function of straight needles and fan needles offer different functionality than other needling tools.
The straight needle setting breaks up clumps, redistributes density and removes air pockets, and the long length allows the needles to reach deep into the coffee bed.

Fan needles

The fan needle setting provides to option to sweep the top layer of the coffee bed and lift chaff and light particles to the surface, reducing ‘choking’ of the brew bed and creating more consistency.

Static reduction

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.

Specialised advantage

The material of the Bloom needles are made of a specially compounded material.
Much stronger than steel, this provides a much smoother movement through ground coffee than other materials, and reduces static in the coffee by up to 20% more than other materials.

FlowTip for more consistency

The Bloom features the FlowTip, a specially crafted tip for creating an indentation in your coffee bed after needling.

A unique feature of the Bloom, it provides a faster and more even saturation, and reduces bubbling and channelling between brews.
