This is where the bistro electric burr coffee grinder comes in and becomes part of the coffee making ritual. The Bistro is continuously adjustable - twisting the upper bean container determines how finely ground the beans will be. With over 14 settings from coarse to fine, you can deliver the ideal grind for any brewing method. But there's more to it than that. Most coffee grinders use plastic containers to receive the ground coffee but plastic and ground coffee don't go together well. The powder gets statically charged and spills all over the place. The new Bistro comes with a borosilicate glass container to catch the grounds.
