What is the best grind for siphon?
The best grind for a brewer is a medium-fine grind, similar to the texture of table salt. This size provides enough resistance to ensure a balanced extraction during the vacuum brewing process without clogging the filter. Because the uses a full-immersion method with a cloth or paper filter, a medium-fine grind helps achieve a clean, vibrant cup.

The , or vacuum brewer, is one of the most visually striking and scientifically interesting ways to brew coffee. It works by using vapor pressure to push water into the upper chamber, where it mixes with the coffee grounds, and then using a vacuum to pull the brewed coffee back through a filter into the lower chamber. Because the coffee is fully immersed in the water for the duration of the brew, the grind size is a critical variable in controlling the extraction.
A medium-fine grind is generally considered the 'sweet spot' for the . If the grind is too coarse, the water will pass through the coffee bed too quickly, leading to an under-extracted, sour, and thin cup. If the grind is too fine, it can create too much resistance, causing the water to stay in contact with the grounds for too long, which leads to over-extraction and a bitter, astringent flavor. Furthermore, an overly fine grind can clog the 's filter, making it difficult for the vacuum to pull the coffee back down.
When dialing in your grind for the , consider the of your coffee. Lighter roasts are denser and may require a slightly finer grind to extract effectively, while darker roasts are more porous and may benefit from a slightly coarser grind to avoid bitterness. The is a very precise brewer, and small adjustments to your grind size can have a significant impact on the final flavor profile.
Because the uses a cloth or paper filter, it produces a very clean cup with a light body, similar to a pour-over but with the added intensity of full immersion. The medium-fine grind helps to highlight the delicate floral and fruit notes that are often associated with high-quality . It is a brewing method that rewards patience and precision, making it a favorite for those who enjoy the ritual of coffee preparation.
In practice, start with a medium-fine grind and adjust based on your taste. If the coffee is too bitter, coarsen the grind slightly. If it is too sour or weak, fine it up. By keeping your grind consistent and using a high-quality burr grinder, you can master the and produce a cup of coffee that is both complex and incredibly clean.
