Optimal grind size depends on many factors including brewing method, roast darkness, bean type and freshness, and more. Experiment with different grind settings to achieve the brew that best suits your taste. If your coffee tastes too bitter, try a coarser grind size. If your brew is weak, adjust to a finer grind size.
1. Remove lid from hopper and fill with whole, roasted beans. Place lid back on hopper.
2. Grip the hopper from the top and slowly rotate to adjust the grind size setting (1 = fine, 15 = coarse). See chart below for grind setting recommendations. NOTE: Adjust the grind size while the motor is running to prevent jamming. 3. Plug into 110V outlet. 4. See pg. 11 for instructions on grinding by number of cups, and pg. 12 for instructions on grinding by grams or grinding manually |
GRIND SIZE SETTING RECOMMENDATIONS
The Grinder lets you grind in 3 modes: cups, grams and manual/portafilter. In cups and grams mode the Grinder weighs output with an integrated scale to ensure consistent and accurate results. In manual/portafilter the integrated scale is disabled.
Note:
• When in “cups” or “grams” mode, make sure to always have the stainless steel plate, the container and the lid on the base when grinding. If they are absent, the Grinder will not work properly. Refer to the Troubleshooting section for more details (pg. 17).
• Once Grinder has started, the display will show the weight increasing until it reaches the desired weight.
• Do not touch the container or shake the Grinder while grinding as it will affect the reading on the scale.
• Grinder will go into sleep mode after 20 seconds of no activity.
• You cannot adjust the number of cups or grams while grinding, but you can stop the grinding process at any time by pushing the OXO button.
To Switch Between Modes
When you first plug it in, the Grinder will default to “cups mode.” To change to a different mode, hold down the OXO button for ~3 seconds, then twist the dial to select your preferred mode. Your Grinder will then default to the last mode used, even after being unplugged.
Cups Mode
To grind based on the number of cups you wish to brew (up to 12):
1. Press the OXO button once to wake up your Grinder. Press and hold the OXO button for ~3 seconds to enter the mode selection menu.
2. Twist dial to select cups mode, then press the OXO button to select.
3. The scale will measure and display the number of cups in the ground coffee container. Twist the dial to select the total number of cups you would like in the ground coffee container.
For example, if there are 2 cups of ground coffee in the container, and you want a total of 8 cups of ground coffee, the number “2” will be displayed with a solid white ring around the OXO button. When you twist the dial, the ring will flash, and you can select the number “8”. When the grinding cycle is complete, you will have enough coffee in the container for 8 cups.
4. Press OXO button to grind.
OXO recommends using approximately 8 grams of ground coffee per cup (5 fl oz). If you want to adjust the pre-programmed setting to be a little less strong or a little stronger, use the strength adjuster (see “To Adjust Coffee Strength” on pg. 13).
Note: Coffee dosage recommendations are based on the SCAA gold cup ratio designed for optimal extraction and strength.
Grams Mode
If you already know how many grams you need for your favorite brewing method, you can grind by grams by selecting your desired quantity, from 1 to 125 grams.
1. Press the OXO button once to wake up your Grinder. Press and hold the OXO button for ~3 seconds to enter the mode selection menu.
2. Twist dial to select grams mode, then press the OXO button to select.
3. The scale will measure and display the number of grams in the ground coffee container. Twist the dial to select the total number of grams you would like in the ground coffee container.
For example, if there are 16 grams of ground coffee in the ground coffee container, and you want a total of 65 grams of ground coffee, the number “16” will be displayed with a solid white ring around the OXO button. When you twist the dial, the ring will flash, and you can select the number “65”. When the grinding cycle is complete, you will have 65 grams of ground coffee in the ground coffee container.
4. Press OXO button to grind.
Manual/Portafilter Mode
You can disable the Grinder’s built-in scale if you want to manually determine the amount of coffee to grind or if you want to grind directly into a portafilter ( ). In the manual mode, the display selection is disabled: you cannot select cups or grams.
If you find your coffee too weak or too strong, you can fine tune the dosage for next time.
1. Move the Strength Adjuster to the right to add a little more ground coffee, or to the left for a little less. Each position of the Strength Adjuster represents a change of one gram per cup. For example, if you select 4 cups and move the Strength Adjuster one position to the right, the Grinder will produce an additional 4 grams. (4 x 8 grams + 4 x 1 gram = 36 grams) |
The Grinder is designed and programmed to work with the steel plate, ground coffee container and lid it comes with.
If you prefer to grind in a different container than the one provided with the unit, you will have to tare the machine (which will set the scale to zero) with the new container on the scale.
Always unplug power cord from outlet before removing or replacing bean hopper.
To Remove Hopper:
|
To Replace Hopper:
NOTE: The bean hopper is designed with a “trap door” that automatically closes when the hopper is removed. The “trap door” allows for easy bean changing and mess-free cleaning.
• Freshly ground coffee is key to making better coffee. OXO recommends grinding coffee immediately before brewing.
• If you don’t grind regularly, make sure to clear the ground coffee from the chute before each use, as some older coffee dust may be sitting inside your Grinder and will affect the quality of your next batch. Without adding beans to the hopper, select 1 cup and grind. Discard the grounds. You are now to ready to grind your fresh beans.
• Coffee flavor and strength is a personal preference. Vary the type of coffee beans, amount of coffee and fineness of grind to achieve the flavor you prefer.
• Do not store beans in the bean hopper for an extended period of time.
• A grind size that is too fine can cause filters/brew baskets to clog and/or overflow. If you experience this, try a coarser grind size.
• Use fresh beans. Old/dry beans will create static. Excess static can lead to dust sticking to walls of Grinder.
Before cleaning, OXO recommends running the Grinder for 10 seconds with an empty bean hopper to help clear beans/grounds from the burrs and grounds chute.
1. Always unplug power cord from power outlet before cleaning.
2. Unlock and remove bean hopper from Grinder by pressing down on hopper release lever and twisting hopper counter-clockwise. See pg. 14 for full instructions.
3. Carefully remove any beans from between Grinder burrs
4. Lift metal burr handle, and twist counter-clockwise. Pull handle straight up to remove upper burr. 5. Clean upper burr, lower burr and grounds chute with a small bristle brush. 6. Align indents in upper burr with tabs inside lower burr. Push upper burr straight into grinder and turn handle clockwise, until you hear a “click.” Note: Continue pressing down while turning handle to ensure upper burr engages with lower burr. |
7. To test proper burr installment, pull metal burr handle straight up. If properly installed, burr will stay in place.
8. Wash the ground coffee container, bean hopper and both lids in warm water and mild detergent, rinse and dry thoroughly.
9. Wash and dry stainless steel plate and wipe free any coffee grounds sitting under plate.
10. Replace bean hopper by aligning icon with arrow, then gently seat hopper straight down.
11. Wipe Grinder exterior with a soft, damp cloth.
Note: Do not use abrasive pads or harsh chemicals to clean Grinder. Do not wash any part of your Grinder in the dishwasher.
