How to Use and Choose a Belgian Royal Coffee Maker

If you’ve ever wanted to turn your morning coffee routine into something closer to a science experiment crossed with a Victorian parlor trick, the Belgian royal coffee maker—or balancing siphon—is your next brewing project. With its striking design and theatrical brewing process, it delivers not just coffee, but an experience steeped in 19th-century elegance.

To use a Belgian royal coffee maker, fill the lower chamber with about 380cc of water, place 40g of freshly ground coffee in the upper glass chamber, light the alcohol burner, and let the vacuum and siphon action brew your coffee at around 95°C. Once brewed, release the air valve and dispense the coffee as it returns through the filter.

What Is a Belgian Royal Coffee Maker?

Also known as a balancing siphon or Balancing Syphon, the Belgian royal coffee maker was originally designed in the 19th century and became a favorite of Belgian royalty. British shipbuilder James Napier is credited with its invention. Though it functions similarly to a siphon or vacuum pot, its unique design includes a pair of connected chambers joined by a curved siphon tube—resembling a balance scale—with one side holding the water over an alcohol lamp, and the other containing ground coffee.

The visual drama is part of the appeal: as the water heats, steam pressure forces it through the siphon into the coffee chamber. After brewing through contact with the grounds at approximately 95°C, the coffee is pulled back down through a filter by gravity and vacuum, leaving the grounds behind. The result? A clean, full-bodied cup with theatrical flair.

How the Belgian Siphon Coffee Maker Works

The brewing process relies on basic physics: heat, pressure, and suction. Here’s the sequence:

• The lower chamber is filled with water and heated by an alcohol burner.
• As the water boils, steam pressure pushes it upward through the siphon tube into the upper glass chamber where the coffee grounds wait.
• The coffee brews at around 95°C as the water and grounds mingle.
• Once all the water has moved into the upper chamber, the heat is removed or reduced.
• Cooling creates a vacuum, which pulls the brewed coffee back down through a filter into the original water chamber, leaving the grounds in the top.
• You then open a valve or spigot to pour the filtered coffee.

Step-by-Step: How to Use a Belgian Royal Coffee Maker

Follow these steps for a successful brew:

1. Prepare the filter. Boil the included filter cloth for 10–15 minutes, rinse it, and attach it to the filter nozzle.
2. Set up the alcohol burner. Fill the burner’s alcohol bottle to about 70% with industrial alcohol and adjust the wick to a low flame.
3. Assemble the siphon. Position the filter nozzle centrally over the glass coffee chamber. Seal the water chamber with the silicone gasket and ensure both sides are balanced.
4. Add water. Pour about 380cc of hot water into the lower chamber and tighten the lid.
5. Add coffee. Place roughly 40g (about 5 level scoops) of freshly ground coffee into the upper glass chamber.
6. Start brewing. Press down the counterweight (gravity hammer), light the alcohol burner, and secure it under the water chamber. The heated water will begin rising into the coffee chamber.
7. Brew time. Let the coffee brew until all the water transfers. For a stronger cup, repeat the process once more after the first brew.
8. Serve. Once brewing is complete, let the coffee flow back down. Loosen the water chamber slightly to allow airflow, then open the tap to pour your coffee.

Frequently Asked Questions

How much coffee should I use in a Belgian royal coffee maker?

Use around 40 grams of freshly ground coffee. This typically equals about 5 level scoops, depending on your grinder’s output. Adjust to taste, but this is the standard amount for balanced brewing.

What water temperature does the Belgian siphon brew at?

The coffee brews at approximately 95°C, ideal for extracting balanced flavours without excessive bitterness. The rise of steam pressure naturally brings the water to this temperature during the process.

Do I need special coffee beans for a Belgian coffee maker?

No special beans are required, but freshly roasted, high-quality beans work best. A medium roast brings out the clarity and complexity this brewing method highlights. FrontStreet Coffee’s Classic Blend and Ethiopia Humbera are excellent choices for siphon brewing.

How do I clean a Belgian royal coffee maker?

Disassemble all parts after each use. Rinse the glass chambers, filter cloth, and nozzle thoroughly. The filter cloth should be boiled occasionally to remove coffee oils. Avoid soap if possible to maintain the flavor purity of subsequent brews.

Why does the coffee go back down after brewing?

After the heating stops, the reduction in temperature causes a vacuum in the lower chamber, which pulls the brewed coffee through a filter back down from the upper chamber, separating it from the grounds.

Is the Belgian royal coffee maker hard to use?

It has a learning curve due to its multiple steps and reliance on precise assembly and flame control, but once mastered, it offers a highly rewarding and theatrical brewing experience.
