Overview

Enjoying Mother Nature's vast beauty shouldn't stop you from appreciating a cup of freshly ground java. The next time you're packing for a most excellent expedition, don't forget the grinder! With a little manual muscle power, GSI's Java Mill will have you savoring a campsite espresso or pour over in no time. Not the outdoorsy type? Keep this grinder as a handy back-up for an unexpected power outage - you'll thank us later!

Features and Functionality

  • Detachable Parts - Remove the handle, silicone grip, grounds container and top of the grinder for easy adjustments and cleaning.
  • Portable - Because the handle is removable, you can easily change the direction in which it sits. Lock the handle horizontally with the silicone grip pointing up for low resistance grinding. When the trail is calling you name, lock the handle vertically against the grinder with the orange grip facing down for a storage friendly shape.
  • Small Bean Storage - The "bean hopper" portion of this portable grinder can hold up to 2 ounces of whole beans.
  • Adjustable Grind - Turn the rotating lever (inside the grounds container) clockwise for a finer grind and counterclockwise for a coarser grind.
Pros
  • BPA Free - The Java Mill is constructed of BPA free copolyester.
Cons
  • Resistance - As with most manual grinders, the finer the grind the more muscle power you will need during the grinding process.
Suitable Applications Coffee Press, Drip Coffee, Espresso, Fine Drip / Pour Over

How long does it take to grind a (coffee) scoop of beans?
charu k on Sep 23, 2014
Best Answer: i drink my morning cup from a large mug and like it fairly strong so I use 2 scoops of a "standard" coffee scoop. i'm grinding one rotation of the adjuster finer than the setting it came preset at. i used the logo on the side of the grinder as a guide. it takes about 2 minutes to grind the coffee. then i toss it into my Bonavita and brew for 5 minutes.

Best 2 out of 3.Review by Nate

I have had two of these, and my roommate has one as well, so that's three examples to draw experience on. They can actually turn a very consistent grind due to the very well supported burr shaft and precise adjustment screw. The design has a few quirks, as others have mentioned, like the bearing on the lid popping out, but that's manageable. The first one cracked during grinding, but two other examples have proven themselves to be quite robust. The handle is a KISS kind of genius, and makes it a lot easier to manage in a backpacking or car camping scenario, whereas with other grinders the handle tends to wander off and get lost. All said, the grinder is a cinch to use, feels good in hand, puts out a decent grind, and is very easy to travel with. (Posted on 12/23/2016)
Great Survival GrinderReview by Brandy

I've had my GSI grinder for about 2 years now and use it every weekend mostly to grind for either my Chemex or French Press when I want to step away from my weekly espresso and don't feel like adjusting that grinder.

Although somewhat heavy for backpacking, I do take it with me on camping trips, I have not experienced any cracking with it but I am very careful as to how I align the lid before pushing down. My biggest complaint is that the center of the metal lid detaches from the plastic ring which is not a huge deal but I do get grease on my fingers when detaching it. I've even degreased this connection point to no success.

Bottom line - this is a great backup grinder to take camping or serve as a weekend grinder; just handle with care. (Posted on 6/1/2016)

Loved the grinder. used it 1 x daily for three weeks and then the plastic cracked. I read many other reviews saying the same thing. I wish it was made better because I loved it until it broke. (Posted on 1/29/2016)
Great for occasional useReview by Robert

I work overseas and am always travelling. This grinder is good for me because it's small enough to toss in my bag and doesn't require power. It works great for a cup or two at a time. Doesn't take more than a minute to get enough ground. The grind settings are easy to figure out and are consistent.
The only issue I've had with it is the top. You pull the top off to load beans, then as you push the lid back on it has to line up or you risk cracking the plastic. I've used it just over fifty times and there's already a crack, but it's still working fine. I'm thinking about wrapping it in duct tape to stop the crack from spreading and for extra grip.
Overall, I'm satisfied with the grinder and will continue to use it, but I can't say it's a good choice for more than a cup here and there. Look from something else if you're wanting a daily use hand grinder. (Posted on 12/23/2014)
