Eureka Olympus KRE: Setup Guide VideoUpdated 6 months ago
Join Victoria as she demonstrates how to set up and dial-in the Eureka KRE Espresso Grinder.
Step one: Out of the box and onto the counter
- Remove the grinder from its box and place it on a solid level surface.
- Inspect the grinder for any damage. If you notice any, contact us immediately.
- Insert the hopper and tighten the hopper screw
- Plug the grinder in and turn it on.
Step two: Feeling the coffee
- Put some beans in the hopper and grind them into your hand.
- Feel the grounds. For espresso, they should feel similar to table salt.
- Not as fine as powdered sugar and not as coarse as sand.
- If it's too fine, adjust the coarser. If it is too coarse, adjust it finer.
Step three: Dialing the dose
- Once the grind is in the ballpark, it’s time to start pulling shots.
- First, grab a scale and tare the weight of the portafilter.
- Fill your hopper and use your portafilter to press and hold the grind button to grind manually. Release the button when the basket looks full.
- Now weigh the portafilter. Add or remove grounds as necessary to get to 20g if you’re using a triple basket or 18g if you’re using a double.
Step four: Adjustments - shot time
- Grip the tamper handle as though you were grasping a doorknob. Tamp straight down and simply lean your weight into it comfortably.
- The amount of pressure is not nearly as important as your consistency and ability to keep the tamp perfectly level so water doesn’t find weak spots.
- Insert your portafilter and start the shot.
- We’re going to be watching for the time of the first drops of espresso to fall between 6 and 10 seconds.
- If they fall outside the window, you’ll have to adjust the grind setting: under six seconds will be thin and sour, so you will need to adjust finer; over 10 seconds will be bitter, so you will need to adjust coarser.
- Make small adjustments. This will be easier than making big changes and over-correcting.
- As the shot progresses, we’ll observe the total shot time: Our target output is 1.5oz (or 30g) liquid espresso in 25 - 30 seconds.
- If it falls under 25 seconds, adjust your grind finer. If it falls over 30 seconds, adjust coarser.
- We recommend making half-digit adjustments at most to avoid over-correcting
- If you find that your ideal setting would be between two numbered settings, we suggest adjusting your dose.
- If your shot is pulling too fast, add a gram or so to slow it down. If it’s pulling too slow, try removing a gram to speed things up.
Step five: Time Dosing
- Now that we have our grind dialed, we can set up the grind timer for consistent and repeatable dosing.
- We find that it takes about 3 seconds to grind a 20g dose.
- Set your desired dose timer to 3 seconds using the plus and minus buttons.
- Select the 3-second dose and press the grind button with your portafilter. It will automatically stop after 3 seconds.
- Weigh the portafilter again. If the dose is too small, increase the timed setting. If it is too much, decrease it.
