Eureka Olympus 75E: Setup Guide Video

Congratulations on your new Eureka Olympus 75E Espresso Grinder. Dialing in your coffee grinder isn't always easy. We discuss the steps to fine-tune your burr grinder for the best possible extraction.

Join Ben as he demonstrates how to set up and dial-in the Eureka Zenith 75E 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 to hold it in place.
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 too fine, adjust coarser. Too Coarse, adjust finer.

Step three: Nailing the dose

Now that the grind is in the ballpark, it’s time to start pulling shots
First, grab a scale and tare the weight of the portafilter
Now use the portafilter to press and hold the grind button until it begins grinding. Holding the button initiates manual grinding mode, so simply release the button when the portafilter basket is full.
Now weigh the portafilter. Add or remove grounds as necessary to get to 18g.

Step four: Adjustments - drop time

Now you can compress the coffee with your tamper. Remember, tamping pressure is less important than making sure your tamp is level.
Insert your portafilter and start the shot. We’re going to be watching for the time of the first drops of espresso.
We’re looking for those 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; over 10 seconds will be bitter.
Make small adjustments. This will be easier than making big changes and overcorrecting.

Step five: Total shot time

Grind a fresh full dose, tamp, and pull your shot.
This time we’ll be looking at the full shot time
We’ll be looking for a target output of: 1.5oz (or 30g) espresso in 25 - 30 seconds.
If it falls under 25 seconds, adjust your grind finer. If it falls over 30 seconds, adjust coarser.

Step 6: Time dosing

Now that we have our grind dialed, we can set up the grind timer for consistent and repeatable dosing.
With the hopper filled set the grind time to 5.5 seconds. This is generally how long it will take to get an 18 to 20-gram dose.
Place your portafilter in the holder and press play and wait until the grinder stops.
Weigh the portafilter again. If the dose is too small, increase timed setting. If it is too much, decrease it.
Now you will be able to get a repeatable target dose
