Fine Grind

Espro Bloom Misc pourover by Prima Coffee Equipment

Prima Coffee's Bloom guide exploits the brewer's perforated base with a fine grind and hot water, using bloom stirring and a later swirl for even saturation. It pursues high extraction, pronounced sweetness, and clarity without choking the bed.

Notes

Break up dry pockets with a brief stir during the bloom, then use a controlled swirl after the later pour to level the bed. Begin fine, but judge by taste and drainage rather than forcing the published pace: coarsen if the finish turns dry or flow stalls, and clean the micro-filter thoroughly after brewing.
