Ligre siji – Grind-by-Weight
The portafilter slides into its cradle, you let go — and without pressing a single button, the grinder starts working. It weighs as the grounds fall, factors in the last bit still in the air, and stops exactly at your dose. What's left is a portafilter with exactly the amount you wanted, not a crumb more.
What makes the siji special
The Ligre siji grinds by weight. A built-in scale continuously measures how much coffee sits in the portafilter, and predictive software accounts for the grounds still travelling between chute and basket — so it hits the set dose to within 0.1 grams. Ligre tested this accuracy with a robot over 50'000 repetitions. If you'd rather dose by time, you can do that too; grinding by weight is the patented feature.
Grinding happens over 55-mm steel flat burrs, infinitely and micrometrically adjustable. Operation is touchless: insert the portafilter, the scale tares itself, and after about a second the grinding starts on its own. Two amounts for single and double can be saved and each fine-tuned to a tenth of a gram. Which burrs are the "best" remains a matter of taste — like engines in a car; our opinion is one of many.

The feeling behind it
Nobody needs a grinder that hits 0.1 grams and operates touchless while doing it. But if you grind a single dose every day and appreciate design clarity, the siji is a piece that connects precision and form. As a design companion to the Ligre youn, it speaks the same language. This decision is an emotional one — and it's allowed to be.
Who it's for
For everyone who wants their dose exact and without detours: insert, grind, pull the shot. And for everyone looking for a grinder that fits the aesthetic of their setup — especially next to a Ligre youn.
The matching setup
The siji is a design match for the Ligre youn from our coffee machines. For pulling the shot, a scale — affordable in the Normcore Collection or with an app in the Acaia Collection —, plus a tamper and WDT tool for puck prep from the Normcore Collection or as a crafted piece from the Weber Workshops Collection.
Frequently Asked Questions
How accurate is Grind-by-Weight, really?
The siji hits the set dose to within 0.1 grams. This works thanks to predictive software that also accounts for the grounds still in the air when it stops. Ligre tested this accuracy over 50'000 repetitions.
Do I need to press a button to start grinding?
No, you insert the portafilter, the scale tares itself, and after about a second the grinding starts on its own, touchless.
Can I also grind by time?
Yes. Alongside grinding by weight, the siji also offers classic dosing by time. Two amounts for single and double can be saved.
Can I see the Ligre siji in person before buying?
Yes, in our showrooms in Bern and Zürich. Delivery takes 2 to 4 business days across Switzerland and Liechtenstein. Financing is available.
As a roastery, we know how much a consistent dose makes for a fair comparison: same grams, same grind size, same time. That's how the character of a rich, full-bodied roast like Cozy Chocolate or Nutty Delight comes through clearly. That's our recommendation, one of many.
