Hario Sommelier Coffee Siphon, 600 mL

The Hario Sommelier SCA-5 is a 600 mL manual coffee siphon made with heat-resistant borosilicate glass. I’d choose it for a slower coffee session when making the brew is as much a part of the morning as drinking it.

Why I like it

I like being able to see what’s happening. The clear chambers put the brewing process in view, and the Sommelier’s rounded lower vessel, flared upper chamber, and curved stand give it a distinct place on the coffee table. This is the kind of brewer I’d bring out when I have time to pay attention, rather than when I need coffee on my way out the door.

I’d approach it as a hands-on brewing method, not a shortcut to a guaranteed result. I can keep notes on my coffee dose, grind, and timing, then change one thing at a time as I work toward the cup I enjoy. That’s part of what draws me to manual brewing: I get to learn the coffee instead of leaving every decision to a machine.

The 600 mL capacity gives me a useful reference for planning a small batch to share. I’d work from the manufacturer’s recipe and fill guidance rather than treat the capacity as a promise of finished coffee volume. Reusable filtration also makes filter care part of my routine. I’d clean it after each session so old coffee residue doesn’t become part of the next brew.

Good to know

Is this an automatic coffee machine?
No. It’s a manual siphon brewer. I’d follow Hario’s setup and heating instructions and stay with it throughout the brew.

Does it make espresso?
No. This is a vacuum coffee brewer, not a pump espresso machine. I’d choose it for brewed coffee and the hands-on process.

How would I care for the glass?
I’d let it cool before cleaning, avoid sudden temperature changes, and follow Hario’s care instructions. Heat-resistant glass still needs careful handling.
