Among grinders, gadgets and gear, one quiet innovation stood out.


One of the most intriguing brewers at this year’s Amsterdam Coffee Festival wasn’t loud, complex or tech-heavy — it was the Hario Suiren, a fresh, elegant take on filter brewing that quietly pulled a crowd all weekend. Light, sculptural and instantly striking, it became one of the festival’s most-talked-about releases — and for good reason.

A New Shape for Filter Coffee

Named after the Japanese word for water lily, the Suiren merges Hario’s signature glasswork with a smart rethinking of water flow. The design is deceptively simple: a broad, petal-like base with a raised centre that looks more like a piece of modern sculpture than a brewer.

But this is no case of aesthetics over function. The wide, shallow bed encourages water to disperse quickly and evenly through the grounds, shifting the extraction dynamic away from the typical cone or flat-bed approach. The payoff is immediate: clean, expressive brews with lifted sweetness and plenty of detail.

Brewing With the Suiren
The Suiren’s charm lies in how intuitive it is. The shallow bed naturally guides you towards a gentle, steady pour, helping flavours open without bitterness, muddiness or overextraction. Expect quicker drawdowns, high clarity and cups that lean bright, aromatic and lively.

It’s a brewer that rewards attention without demanding precision stress — ideal for home brewers chasing elevated simplicity, and café bars looking to add a moment of quiet theatre to their service. Not just a pretty object, but a thoughtful new take on what filter brewing can feel like.
