This electric burr grinder crushes the coffee beans between conical burrs rather than chopping them, preventing the coffee from losing its characteristic taste and aroma. Variable grind settings can be adjusted by twisting the bean container--from a coarse grind for French presses all the way down to a fine espresso grind. The static-free borosilicate glass container inserts into the base of the unit to collect ground coffee and features a non-slip silicone band for secure handling.
