How to Brew Coffee with a Belgian Royal Coffee Maker

If you’ve ever seen a dramatic, two-tiered glass-and-metal coffee maker bubbling away at a café table, chances are it was a Belgian Royal Coffee Maker. Known for its striking design and theatrical brewing process, it’s often used in fine dining or upscale coffee service—but many find the resulting cup weaker than expected.

To brew coffee with a Belgian Royal Coffee Maker properly, heat 400–450ml of water in the lower metal chamber, add roughly four level scoops of medium-fine ground coffee (about 4 tablespoons) into the upper glass bulb, ignite the alcohol lamp beneath, and let the device self-brew. Once brewing finishes and the coffee draws back down, simply release the valve and pour.

What Is a Belgian Royal Coffee Maker?

The Belgian Royal Coffee Maker, also known as a balancing siphon or a two-chamber siphon brewer, is a historic coffee brewing device once associated with European royalty. Its elegant glass and metal construction makes it a centerpiece for tableside service, especially in high-end cafés or restaurants aiming for a dramatic presentation. While visually impressive, its short contact time between water and coffee grounds often leads to under-extracted, lighter-bodied coffee.

Why Does It Produce a Lighter Cup?

The main drawback of the Belgian Royal Coffee Maker is its limited brew time and extraction efficiency. Because the hot water doesn’t linger long enough with the coffee grounds, it tends to under-extract key flavor compounds. This results in a cup that is often described as mild, delicate, or even weak—especially when compared to immersion or pressure-based brewing methods like French press or espresso.

Step-by-Step: Brewing Coffee with the Belgian Royal Coffee Maker

Follow these exact steps to operate the Belgian Royal Coffee Maker for best results:

• 1. Prepare Your Equipment: You’ll need a full Belgian Royal Coffee Maker set and ensure the alcohol lamp is fully fueled.
• 2. Heat the Water: Pour approximately 400–450ml of water into the metal (lower) chamber of the brewer.
• 3. Add Coffee Grounds: Grind around four level scoops (approx. 4 tablespoons) of coffee beans to a medium-fine grind size, similar to table salt. Place the grounds in the upper glass chamber.
• 4. Ignite the Lamp: Light the alcohol lamp located under the metal chamber and hold down the lamp cover to stabilize the flame.
• 5. Begin Brewing: As the water heats, it will rise into the upper chamber through vapor pressure, mixing with the coffee grounds. Allow the mixture to brew automatically.
• 6. Observe the Process: The coffee will brew as the water interacts with the grounds in the upper chamber. This part of the process is both functional and visually engaging—often served as part of the café experience.
• 7. Serve the Coffee: Once brewing completes and the coffee draws back down into the lower chamber due to gravity, turn off the heat, wait briefly for the coffee to finish ‘back-siphoning,’ then open the release valve and pour through the tap.

Frequently Asked Questions

How much coffee should I use in a Belgian Royal Coffee Maker?

Use about four level tablespoons—or roughly four scoops—of coffee grounds. This typically equates to around 20–24 grams, depending on your scoop size.

What grind size works best for the Belgian Royal Coffee Maker?

A medium-fine grind is ideal, similar to the texture of table salt. Avoid grinding too coarse, as it may lead to under-extraction, or too fine, which could slow drainage or clog the filter.

How much water should I put in the bottom chamber?

Pour between 400 and 450 millilitres of water into the metal (lower) chamber before heating. This ensures enough water will siphon into the upper chamber for proper brewing.

Why is my coffee coming out weak or light?

The Belgian Royal Coffee Maker has a short brew time and limited contact between water and coffee grounds, often leading to under-extraction. This results in a lighter-bodied and more delicate cup, which is a known characteristic of this brewer.

Do I need to do anything special to serve coffee from this device?

Once brewing is complete and the coffee has drawn back down into the lower chamber, make sure to turn off the alcohol lamp, wait a moment, then open the release valve before pouring through the tap. Always ensure the valve is opened for safe and clean dispensing.
