What is the best grind size for V60?
The best grind size for a V60 is typically medium-fine, similar to the texture of sea salt. Because the V60 uses a paper filter and a large drainage hole, this size provides the ideal resistance for water to flow through, ensuring balanced coffee extraction. You should adjust slightly finer for lighter roasts and coarser for darker roasts to manage flow rate.

The V60 is a pour-over method that relies on gravity and the specific geometry of its cone to extract flavor. Because it features a large, open drainage hole at the bottom, the grind size is the primary variable you have to control the flow rate and, consequently, the extraction time. If your grind is too coarse, the water will pass through too quickly, resulting in a sour, under-extracted cup. If it is too fine, the water will stall, leading to over-extraction and bitterness.
For most standard V60 recipes, a medium-fine grind is the starting point. Think of the texture of table salt or slightly finer sea salt. This provides enough resistance to keep the water in contact with the coffee grounds for the duration of your pour, typically between 2:30 and 3:30 minutes for a standard 15-20g dose. However, this is not a static rule; it must adapt to the coffee you are using.
and are major factors. Lighter roasts are denser and harder to extract, so they often benefit from a slightly finer grind to increase surface area. Darker roasts are more porous and soluble, meaning they extract very easily; if you grind them too fine, you risk pulling out harsh, ashy flavors. In these cases, a slightly coarser grind will help maintain balance.
In practice, the best way to find your 'sweet spot' is to use the V60's flow as a guide. If your brew finishes too quickly and tastes thin, tighten your grind. If it takes too long and tastes bitter, coarsen it. Remember that the V60 is a very transparent brewer—it will highlight both the brilliance of a high-quality and the flaws of an uneven grind. Using a consistent burr grinder is essential here, as a mix of boulders and fines will lead to an uneven extraction that no amount of pouring technique can fix.
