When brewing pour-over coffee, the filter cup actually holds quite a few clues. The size of the dome that the coffee bed puffs up into during the blooming stage, and how well it retains water, can reflect the freshness of the coffee beans and the depth of the roast; whether the coffee bed can be lifted indicates the density of the coffee grounds; the color change of the foam on the surface can help us track the pouring path; and the speed of the drawdown is related to the coarseness of the grind, the density of the coffee bed, and fine particle clogging. As for the deep coffee bed pit that many beginners obsess over, it does not directly equate to a better-tasting cup; it is more just a reflection of the pouring method. In this article, Front Street will break down these readable pieces of information one by one during the brewing process, to help you have a few more bases for judgment when adjusting parameters.
