Hario Sommelier Coffee Siphon

The vacuum method uses vapor pressure to push water up into the brewing chamber and then pulls the coffee back down through a filter. This process creates a very clean, tea-like body that highlights the delicate aromatic notes of the beans, often producing a brighter cup than a standard drip machine.

Yes, the Hario Sommelier comes with an alcohol burner. It requires a bit of practice to manage the flame and heat consistency, but it is a straightforward process once you get the hang of the timing.

The Hario Sommelier is specifically designed to be used with the included alcohol burner. Using it on a direct stovetop flame can cause uneven heating or damage the glass, so it is best to stick to the intended heat source.

While borosilicate glass is heat-resistant and durable, it is still glass and requires careful handling. It is sturdy enough for daily use, but you should avoid sudden temperature shocks and handle the carafe with care during cleaning.

You should aim for a medium-fine grind, similar to what you would use for a pour-over or a slightly finer drip coffee. If the grind is too coarse, the coffee will be weak; if it is too fine, the filter may clog and the brew time will be too long.

Cleanup is more involved than a standard coffee maker because you have to disassemble the upper and lower chambers and clean the filter assembly. However, the glass components are easy to rinse, and the ritual of cleaning is part of the overall experience for most siphon enthusiasts.
