Olympia Express Puck Prep Tool 49mm – Distribution Tool for Cremina, Made in Switzerland
You dose your coffee, press the tamper, pull the shot – and the espresso flows faster on one side than the other. Channeling. A clump in the puck, a depression, an unevenness. This is precisely where the Olympia Puck Prep Tool comes in. With fine stainless steel needles, guided by a wooden handle from Schwanden, you break up clumps and distribute the ground coffee evenly in the basket. What sounds like a detail can determine the aroma – or bitterness – in your cup.
What makes this tool special
Clean Distribution Before Tamping
Freshly ground coffee doesn't fall evenly into the basket. Clumps, small valleys, and dense corners form. When you then tamp, the puck looks even on top – but it isn't on the bottom. During extraction, the water takes the path of least resistance, and the espresso develops bitter notes in one spot and a thin taste in another. The Puck Prep Tool breaks up these clumps before tamping and distributes the ground coffee homogeneously. The result: consistent extraction, no channeling, more sweetness.
Swiss Craftsmanship, Olympia Style
Wooden handle in the well-known Olympia look, stainless steel needles, all from Schwanden in the canton of Glarus. Just like the Cremina itself: no superfluous designs, just a tool that does its job. Typically Olympia, understated and built for longevity.

Three Ways to Puck Distribution – Honestly Compared
For puck distribution, we offer three legitimate options that meet different needs – and frankly, three very different price points.
Affordable and Proven: Normcore
The Normcore WDT-Tool has been the tool for most home baristas to get into the WDT workflow for years. Solidly built, several fine needles, magnetic stand. Functionally, it does what you expect from a WDT tool. If you simply want even distribution without a premium surcharge, this is a good choice.
Swiss Original: Olympia Express
This tool here. Wooden handle in Olympia aesthetics, from Schwanden, manufactured in the same factory as your Cremina. For anyone who wants to keep their Cremina setup consistent – machine, tamper, distribution tool, all from the same house. The price is significantly higher than Normcore, but below the Weber premium level. Those who appreciate Swiss craftsmanship and aesthetic consistency will find an honest choice here.
Premium Level: Weber Workshops Moonraker
The Weber Workshops Moonraker works differently from a classic WDT tool: rotating needles, precise geometry, significantly larger investment. For those who want the endgame of puck distribution and are willing to pay significantly more for it. Surprisingly elegant in workflow, especially for professionals and ambitious home baristas who want to prepare every shot reproducibly.
Our opinion: For 90% of Cremina owners, the Normcore WDT tool is functionally perfectly adequate. Those who want the Swiss-made setup choose Olympia. Those who work at Weber premium level usually also have a Linea Micra or larger in their setup and use the Moonraker there rather than with a Cremina.
Who this tool is for
For Cremina owners who want to make their shot more consistent and value Swiss craftsmanship. Those who are still getting into the WDT workflow and just want to try if it makes a difference can also do so with the cheaper Normcore tool – the learning effect is the same. But those who already know that WDT is part of their workflow and want a tool for the next 15 years that matches their Swiss-made machine, are in the right place here.
Accessories that fit the Cremina setup
Original Cremina 49 mm tamper (red or black) from the Olympia Express Collection. Tamping mat: affordable from the Normcore Collection or as a Swiss original also from Olympia. Dosing funnel for clean filling of the basket: Olympia original 49 mm or Normcore Dosing Funnel, premium Weber Workshops Dosing Cup. Grinders crucial for grind quality: Grinder Collection. For precise dosing: Acaia scales.
Frequently Asked Questions
What does WDT mean?
WDT stands for Weiss Distribution Technique, named after John Weiss. The principle: fine needles are moved through the ground coffee in the portafilter to break up clumps and distribute the ground coffee evenly. The result is a homogeneous puck that extracts evenly.
Do I really need this tool?
Need is a strong word. If you just want to make nice espresso with the Cremina, you can do without it. But if you have channeling problems or want to get the last bit of consistency out of your shot, a distribution workflow will noticeably benefit you. It's part of the learning curve, not a miracle cure.
What is the difference to the Normcore WDT tool?
Functionally very similar. The Olympia tool is Swiss craftsmanship with a wooden handle, the Normcore tool is Asian mass production with a stainless steel handle. Both have fine stainless steel needles. The price difference mainly reflects the place of manufacture and aesthetics, less the function.
How do I clean the Puck Prep Tool?
Tap it off briefly after each use, occasionally rinse with warm water. Do not put the wooden handle in the dishwasher, otherwise the wood will suffer. Place it on a tamping mat or a grinder brush holder.
Where can I buy or see the Puck Prep Tool live?
Online via coffeecoachingclub.ch with delivery in 2–4 business days to Switzerland and Liechtenstein. On-site in our showrooms in Bern (Gerberngasse 44, 3011 Bern) and Zurich (Hagenholzstrasse 50b, 8050 Zurich). Click and Collect possible. Financing possible.
Roastery Tip
We have been using WDT workflows in our showrooms for years because they allow us to work more reproducibly. But it's not a miracle cure: if the grinder doesn't grind evenly or the beans are old, even the best distribution tool won't help. The order in the learning curve, as we see it: first, fresh beans (roast date 7–28 days), second, a good grinder, third, stable water quantity and brew ratio, fourth, tamping, fifth, then puck prep. If you skip step 1, you won't gain much with distribution tools. If you have steps 1–4 clean, a puck prep tool will give you that last bit of consistency – and that's fun.
