Apr 11, 2019· An extracoarse grind is best for cold brew coffee. As the brew method with the longest extraction time, cold brew coffee does not require as much surface area to fully extract flavor from the grounds. If you try to brew cold brew with a fine grind, you''ll end up with a bitter, over extracted result even though you''re using cold water.
