Brewing coffee is an art, and grind size plays a huge role in the final flavor of your cup. It controls how water pulls flavors from the beans. Especially for organic dark roast beans, the grind size can highlight or hide bold, rich notes. Starting with the right grind helps you brew delicious coffee every time. Roast28’s recipes provide clear instructions on coffee-to-water ratios and recommended grind sizes, making it easy to get started.
Understanding dark roast coffee and grind size
Dark roast beans are roasted longer, creating bold flavors with chocolate, caramel, and smoky hints. Beans that are roasted longer also become oilier and more porous. Because of this, dark roasts usually do better with a slightly coarser grind than lighter roasts. Using the right grind size lets you balance extraction and bring out the best notes. Too fine a grind risks bitterness, while too coarse might taste weak or flat.
How grind size affects flavor and body
Grind size affects how fast water extracts coffee flavors and the body of your brew. Finer grinds create stronger, fuller-bodied cups but can lead to bitterness if over-extracted. Coarser grinds produce smoother, lighter coffee but may under-extract and taste weak. For dark roast, finding the right grind is key to keeping those rich flavors bold yet smooth.
Matching grind size to brewing method
Different brewing methods need different grind sizes. For dark roast coffee, French press and espresso generally use coarser grinds to balance extraction and flavor. Pour-over and AeroPress often call for finer grinds to intensify bold notes. Additionally, brew time should match your grind size. Use longer brew times with coarse grinds (like French press) and shorter times with fine grinds (like espresso) to extract balanced flavor.
