The most important thing about brewing coffee
Every coffee grind is a slightly different size and shape, experiences a different flow and duration of water, and comes from a slightly different portion of the coffee bean. This means that every brew is a mixture of hundreds and thousands of individual tiny micro-extractions. Some are extracted more, some are extracted less, some sit in the middle. It’s this cacophonous mix of different extractions that all work together to make a cup of coffee.
