In the practice of pour-over coffee, one detail that is often discussed is: should the coffee grounds around the edge be moistened with water? This article starts from the two stages of blooming and the main extraction, and, combined with comparative experiments on light, medium, and dark roast levels, analyzes the impact of the pouring range on flavor. The experiment shows that whether to wet the outer layer of grounds during blooming depends on whether all the coffee grounds can evenly absorb water and release gas in the shortest time. Not pouring around the outer ring tends to cause inconsistent extraction rates, and light and medium roast beans are prone to a grassy, unripe taste; while pouring directly onto the outer ring may block gas release in the center. The article also shares practical techniques such as swirling and stirring to help coffee enthusiasts extract every particle of coffee grounds more evenly. [more…]
