JAVA manual coffee grinder was built to make great coffee easy and intuitive to achieve. VSSL's signature Clip and Flip lever serves both as a carrying handle that can be clipped onto your pack and an extendable crank so you get the smoothest, easiest rotation while grinding. A magnetic handle attaches for added ease of use. The top simply pops off with the push of a button - so loading your beans is simple. Stainless steel bearings on both the top and bottom ensure a consistent grind size and reduce the dreaded “wobble” experienced with other grinders. JAVA only takes 60 seconds of cranking to produce around 20 grams of ground coffee — perfect for a single cup. VSSL really thought of everything with this one. This is really the ultimate manual coffee grinder.
