Congrats on embarking on your new coffee adventure! You’ve officially taken the first step on the road to becoming a worldly coffee aficionado. Take pride in the fact that you are now a part of a tradition that dates back to the 15th century and has carried on throughout our history, across cultures. Our manual burr coffee grinder will give you the power to unleash the true potential of your favorite coffee beans.

What Size Coffee Grind to Use

Now that you have your Wandercup grinder and your beans ready, it’s time to learn about the right grind size. Choosing the grind size depends on your method of brewing.

With your grinder, turn the adjustment knob all the way to the right. Each number in the table below represents a “click” to the left.

Setting up your first Wandercup Grind

  1. Remove lid and fill hopper with the desired amount of whole bean coffee you wish to grind.
  2. Adjust your grind size by turning the adjustment knob clockwise (finer) or counter-clockwise (coarser). See table above for more information this step!
  3. Grip the grinder firmly at the midpoint, turning the handle in a clockwise direction.
    Warning: Significant damage can occur to your burr grinder by spinning the handle counter-clockwise.
  4. Once finished grinding, remove the container and pour your freshly ground coffee into your brewer of choice. Enjoy!

Grind Tips

If your coffee is too weak or watery:
Try using a finer grind size. This will increase the surface area and extraction.

If your coffee is too strong or bitter:
Try using a coarser grind size. This will decrease surface area and extraction.

You might have to experiment a bit to get your coffee exactly the way you love it, but that’s part of the adventure!

Cleaning Your Wandercup Grinder

We recommend washing the grinder before your first use. Allow it to fully dry before grinding your coffee.

We also suggest cleaning your grinder every month to remove build up of fine particles and oils that can cause stale and undesirable flavors in your brew.


  1. Unscrew and remove the grounds catcher from the bottom of the grinder.
  2. Unscrew the adjustment knob, then grasp the bottom edge of the inner burr mill.
  3. Pull the burr away from the grinder to slide it off of the axle.
  4. There is a plastic insert that sits below the burr mill, and a spring and small washer that sits above the burr mill. These are used to level and adjust the burr. Remove.
  5. Carefully remove the top of the grinder from the hopper.  Do not wash the top handle assembly; it contains a gearbox that can be damaged if exposed to water.
  6. Remove the axle from the hopper.
  7. Gently hand wash the hopper, grounds catcher, and burr. A toothbrush is useful to clean the burr mill.
  8. Allow to air dry.
  9. Once everything is clean and dry, insert the axle into the hopper (the screw should be at the bottom). Then place and lock the top onto the hopper. Then replace the washer, spring, the inner burr mill, bottom insert, and tighten the adjustment knob onto the axle.
  10. Place and lock the grounds catcher to the hopper.

Additional Tips

  • Make sure the grounds catcher is screwed on tight before grinding.
  • Gently shake the grounds catcher to pour the grounds out of it.
  • Very lightly roasted, small, and stale beans are harder to grind.
  • Grind your coffee right before brewing. Once coffee is ground it will quickly lose it’s best flavors and aromas.
  • Place the grinder on a flat, smooth surface and hold in place while turning the handle.
  • Place the grinder on the top of your thigh, with knees bent. Hold in place and begin grinding.
  • Wrap your hand around the hopper, just below the top. Gently turn the handle to grind.


  • Your Wandercup grinder was designed to grind coffee beans. We do not suggest grinding anything but roasted coffee beans.
  • If the handle becomes hard to turn, try shaking the grinder or turning the handle in reverse to dislodge any hard or stuck beans.
  • Ceramic is a brittle material. The burr can break if dropped on a hard surface.  Replacements are available by contacting us at
  • Do not use an electric drill to power the grinder. This can cause unnecessary stress on the components and lead to parts breaking.
  • Keep out of the reach of children. There are small components which can act as choking hazards.
