Yama Glass BN1 Butane Burner for Siphon Coffee Makers

The Yama Glass BN1 portable butane burner is an adjustable heat source for tabletop siphon coffee makers, also called vacpots or vacuum brewers. If you're putting together a siphon setup or replacing an alcohol burner, this is the part that supplies the heat beneath the brewer.

What I like about this setup is the ability to adjust the flame. Siphon brewing is hands-on, and a flame control lets you change the heat instead of working with one fixed setting. Electronic ignition handles lighting, while the refillable butane tank keeps the burner ready for the next refill rather than making it a disposable piece of gear.

Will it work with your siphon?

This burner can be used with Yama CNT5, TCA3D, and TCA5D coffee makers. It works with both Yama tabletop siphon configurations, including as a replacement for the alcohol burner on the tabletop model originally fitted with one. It is also offered as a separate heat source for standard vacpot setups.

If you're shopping for your first siphon burner, I'd start by checking your brewer's model and the space beneath it. The burner measures 125 × 80 × 76 mm, so those dimensions are worth comparing with your setup rather than assuming every stand has the same clearance.

What makes it useful

• Adjustable flame: Change the heat level as you work through your brew.
• Instant electronic ignition: Light the burner using its built-in ignition system.
• Refillable butane tank: Holds 30–35 g of butane fuel.
• Approximate working time: About 45 minutes.
• Portable format: A compact micro-burner for a tabletop brewing setup.

About Yama Glass

Yama Glass makes hand-blown specialty glassware in Taiwan, including cold brew towers, siphon coffee makers, and teapots. Its glassware is tempered and heat resistant; this BN1 burner is a separate accessory for supplying heat to a compatible brewer.

For me, the reason to choose this burner is straightforward: adjustable heat, electronic ignition, and a refillable tank in a compact format. Check your siphon model first, then build your brewing setup around the right fit.
