Chemex 10 Cup

Fine Grind

Counter Culture Coffee's Chemex technique is expanded to the 10-cup brewer with a somewhat finer grind than many large-batch approaches and careful bloom mixing. The intended cup is clean, sweet, balanced, and fully developed.

Notes

Stir only enough during the bloom to wet the deep bed from top to bottom, then pour evenly to avoid carving channels. The finer starting grind raises extraction through the dense filter; coarsen it if the batch stalls or develops a papery, drying finish.
