A BOOST FOR YOUR BREW
From Nucleus Coffee Tools, Bloom is a brew bed preparation tool designed to improve extraction and flavour consistency for filter coffee.
Bloom takes the principle of the Weiss Distribution Technique (WDT) even further, incorporating an advanced set of distribution needles to separate clumps, manage fines, and lift non-soluble materials in filter coffee beds – all before the first drop of water hits.
The Nucleus Bloom distribution tool helps to remove common issues in conical pour-overs, immersion drippers, flat-bed brewers, and more with a controlled and repeatable preparation process. With a satisfying and user-friendly design, Bloom is the perfect tool for beginner home baristas and professionals.
Never struggle with overwhelmingly bitter, acidic, or dull coffee again. With up to 15 precision needles and FlowTip™ technology to reduce variability between brews, the Nucleus Bloom gives you more consistent extractions and richer flavours in every cup (it can even be used in the preparation of espresso!)
Three Functions, One Compact Design
With its sleek and transportable shape, the Nucleus Bloom is not much larger than your average WDT tool. Hidden inside are three unique functions, each one thoughtfully added by Nucleus Coffee Tools to create uniform density, remove insolubles, and promote optimal water flow.
- Deep distribution for improved flavour distinction and sweetness.
