Blade grinders do not have grind settings - to grind finer, you will simply grind for a longer amount of time. Burr grinders do have grind settings from coarse to fine, which allow you to get the perfect grind no matter what brewing method youre using and create a more even and consistent grind than blade grinders can provide. Im not sure how fine youll need your grinds, but there are a couple of models I can recommend: the Krups Burr Grinder and the Bunn BCG. Both models have the ability for you to change the grind setting and select how much youd like to grind based on the number of cups.
