Blooming is an indispensable preparatory step in pour-over coffee. It works by wetting the coffee grounds with a small amount of hot water, releasing carbon dioxide and using capillary action to connect the particles, laying a uniform and efficient foundation for subsequent extraction. Many people are in the habit of always using a fixed 30 seconds, but coffee beans in different states actually have different requirements for bloom duration. Freshly roasted beans and light-roast, high-density beans need a suitably extended degassing time, while beans that have been sitting for too long or dark-roast beans are the opposite. This article will guide you through how to flexibly determine when to end the bloom based on the beans' gas content, roast level, and the wetness of the coffee bed and the frequency of off-gassing during blooming, as well as master pouring techniques for evenly wetting the coffee bed, bringing every cup of pour-over closer to perfection.
