Hario Technica Coffee Syphon, Made in Japan
Hario
Technica Coffee Syphon
The best documented brewer in this roundup. Coffee touches glass, steel, and cloth, with one silicone rubber gasket at the neck; the plastic parts are the lid, spoon, and lamp holder, and Hario says so plainly. If you want the syphon experience with honest paperwork, this is it.
Theatrical vacuum brewing in Japanese heatproof glass. The brew happens in borosilicate glass through a cloth dressed steel filter; a silicone rubber gasket seals the two bowls and a few non brewing parts are polypropylene.
How this score breaks down
Strengths
- Brew happens entirely in borosilicate glass through a cloth and steel filter
- Hario publishes the material of every single part, the best disclosure in this roundup
- Every bowl, filter, and even the cloth is sold as a spare part
- Made in Japan by a century old family glassmaker
Trade-offs
- A silicone rubber gasket sits in the brew path where hot water passes twice
- Lid, measuring spoon, and lamp holder are polypropylene, though outside the brew
- The stand contains phenol resin, an early hard plastic
- Needs burner fuel and a careful hand; this is the fussiest way to make coffee

- Packaging
- Individual cardboard box per Hario's spec sheet; box contents beyond the brewer are listed in the manual.
- Microplastics
- Silicone is not a petroleum plastic and is not a microplastic source the way plastic is, though as a polymer it can release trace particles or siloxanes, more so with heat and age. Whether silicone forms microplastics is still an open question. The polypropylene parts stay out of the brew.

About Hario
Hario is a Japanese glassmaker founded in Tokyo in 1921 as the Hiromu Shibata Works, and its name means king of glass. The company is still led by the Shibata family and has melted its heatproof glass with electricity instead of oil since 1972. Coffee lovers know it for the V60 dripper line, syphon brewers, kettles, and teapots, alongside the lab glassware where it started. The Technica syphon is made in Japan and Hario publishes a complete material list for it, down to the brass fastener and the cotton lamp wick. The company has sold replacement parts since 1950, and every glass bowl and filter for this brewer can be bought separately. Disclosure this complete is the exception in coffee gear, not the rule.
