When faced with a coffee bean you've never encountered before, how do you quickly develop a suitable pour-over plan? This article starts with simplifying the brewing framework and shares a practical method: first roughly categorize coffee beans by roast level, establish a highly versatile brewing plan for each category, and then identify where unfamiliar beans belong through flavor descriptions and bean color. As experience accumulates, gradually refine the categories, deriving medium roast from light roast and dark roast, and even making further adjustments for special varieties such as Geisha. Front Street Coffee uses its own two brewing plans as examples to show that by keeping the dose, ratio, and technique consistent and adjusting only the water temperature, grind size, and dripper, most beans can be handled. This approach not only reduces decision-making costs but also leaves room for subsequent optimization. [more…]
