To make a decent espresso at home, you need to get three things straight: how much coffee you use, how much liquid you extract, and how fine you grind. The standard reference is a 1:2 coffee-to-liquid ratio—about 9 grams of coffee yielding 18 grams of liquid for a single shot, and 18 grams of coffee yielding 36 grams for a double, with the actual output fine-tuned to taste. As for grind size, watch the flow rate: if it runs fast, grind finer; if it runs slow, grind coarser, until the extraction time falls within the right range. The roast level of the beans also matters a lot—medium-dark roasts and darker make it easier to achieve a balanced flavor. Drawing on the real-world parameters of Front Street Coffee's classic blend, this article lays out the extraction logic clearly in one go. [more…]
