How do I adjust my grinder for different beans?
Adjust your grinder for different beans by focusing on and . Lighter, denser roasts generally require a finer grind to extract properly, while darker, more porous roasts extract easily and often need a coarser setting. Always make small, incremental adjustments and brew a test cup to dial in the flavor for each new coffee.

Every coffee bean is unique, and your grinder settings should reflect that. When you switch from a light-roast Ethiopian coffee to a dark-roast Brazilian , you are changing the physical properties of the material you are grinding. Light roasts are denser and harder, meaning they resist water penetration and require more surface area—a finer grind—to extract their delicate floral and acidic notes. Dark roasts, having been roasted longer, are more porous and brittle; they release their compounds very easily and can quickly become bitter if ground too fine.
Beyond , is a major factor. High- coffees are often denser than those grown at lower elevations. If you find that your current grind setting is producing a weak, sour cup with a new bag of beans, it is a sign that the coffee is not extracting efficiently. You should move your grind setting finer. Conversely, if the coffee tastes harsh, ashy, or overly bitter, you have likely over-extracted the beans, and you should move your setting coarser.
It is also important to account for the 'retention' in your grinder. Most grinders hold a small amount of ground coffee in the chute or around the burrs. When you change your setting, the first few grams of coffee that come out will be a mix of the old setting and the new one. To get an accurate result, purge a few grams of coffee through the grinder after making an adjustment before you brew your actual cup.
In practice, keep a simple log of your settings. Note the coffee, the , and the setting you used. Over time, you will start to see patterns—for example, you might find that all your light-roast pour-overs perform best at a specific number on your dial. This takes the guesswork out of your morning routine. Remember that the goal is not to find a 'perfect' setting for all coffee, but to find the setting that allows each specific bean to express its unique character. Don't be afraid to experiment; the best cup of coffee is often found just one or two clicks away from your current setting.
