Grind size

Grind size refers to how finely or coarsely the coffee beans are crushed, which directly regulates how fast water extracts the flavors. Think of it like water flowing through sand versus gravel; finely ground coffee slows the water down for a rich, intense brew, while a coarse, sea-salt texture lets it flow faster. Matching the grind size to your specific brewing equipment is the easiest way to prevent your cup from tasting either unpleasantly sharp or weak and watery. Finding the sweet spot can turn a flat-tasting coffee into a vibrant explosion of natural sweetness. Behind the bar, we often say that a high-quality grinder matters even more than the coffee maker itself.
