Siphon coffee brewer

The siphon coffee brewer is a brewing method that combines science and aesthetics, producing a clean and aromatic beverage through vacuum extraction.

About this subject

The siphon coffee brewer, also known as a vacuum coffee maker, was invented in Germany in the 1830s by Loeff of Berlin and later refined in France. The method uses two glass chambers: the lower one holds water that is heated, creating steam that pushes water into the upper chamber, where ground coffee is infused. After boiling, heat is removed, and the vacuum pulls the filtered coffee back down. This visually striking process yields a clean cup with light body and intense aromatic notes.

In Japan, the siphon gained popularity from the 1920s, becoming part of the coffee ceremony in specialized cafés. Today, it is cherished by baristas and enthusiasts who value the ritual and precision. Unlike the French press or paper filter, the siphon extracts essential oils and volatile compounds efficiently, resulting in a coffee with low acidity and natural sweetness. Water temperature (around 92-96°C) and brew time (about 1 minute) are critical for balance.

Interestingly, the siphon was used in chemical laboratories in the early 20th century before becoming a coffee brewing method. Its popularity declined with the rise of espresso machines but has resurged in the third wave coffee movement, particularly in specialty cafés aiming to highlight the sensory attributes of single-origin beans. Cleaning the equipment is vital to avoid off-flavors, and cloth or metal filters replace paper, allowing more oil passage.

Frequently Asked Questions

Is the siphon coffee brewer difficult to use?

It requires practice to control temperature and timing, but with basic instructions, an excellent cup can be achieved. The ritual is part of the appeal.

What is the difference between siphon and French press?

The siphon uses vacuum for filtration, resulting in a cleaner beverage without sediment. The French press retains oils and fine particles, giving a fuller body.

What type of coffee should be used in a siphon?

A medium to fine grind, similar to paper filter, is recommended. Light to medium roasts best highlight the aromatic notes.
