Like other adjustable factors in coffee brewing, ground density can affect taste. Key things to consider when adjusting your coffee grinder are brewing method, roast, and bean origin. Brewing methods that involve high heat and pressure for short extraction times call for finer grounds. Other methods involving lower pressure and longer brewing times require a coarser grind. Lighter roasts can be ground finer, while dark roasts work better as coarse grounds. If you’re shopping for a coffee grinder, we recommend a burr grinder as found in
De'Longhi Bean to Cup coffee machines.
