If you're a coffee snob (or you just like brewing great coffee on-the-cheap), you likely grind coffee beans fresh with each brew. The inexpensive JavaGrind hand-crank mill grinds more uniformly than electric blade grinders and works when you don't have power.
I recently noticed how inconsistently my electric grinder was grinding my beans — a problem that results in both overly powdery and chunky grounds. The result: sometimes sludgy, sometimes overly weak brews (particularly with coffee presses). After a bit of research, I learned that coffee aficionados swear by burr grinders over blade grinders for more consistent grounds. The problem: really good burr grinders are often extremely expensive.
JavaGrind's hand-crank coffee mill is a hand-powered burr grinder that only costs around $US20 and comes highly recommended from great-gear blog Cool Tools. Not only do you get the burr grind, but as a hand-powered gadget, it works wherever you are, whether for your daily office grinds or on an electricity-free camping trip.
