Mahlkonig EK43 factory taste

Grinders are one of the keys to exceptional espresso. Discuss them here.

After two years with a trusty Breville Smart Grinder Pro I saved my pennies and just got an EK43s. I'm curious how many pounds of coffee I should expect to grind before the factory taste wears off. The first coffee was undrinkable. I didn't bother brewing the second. The third was still unpleasantly metallic. Should I just get a big five pound bag of Costco swill, grind it, and take it to the break room at work?

Not sure what factory taste is. If your coffee is undrinkable I wouldn't put that down to entirely to the burrs not being seasoned .
If you wanna put some oily beans down it be my guest but they will leak a residue too.
When i got mine i put 10kg in it, but i wasnt seeing a factory taste before this .
The EK is a different thing and i wouldnt be trying to pull short brew ratio espresso with it , that will not lead to tasty .

There will no follow a series of posts relating to the fact the a factory EK makes garbage coffee and you will need to align it, buy new burrs and pre breaker....

The EK43 is radically different from all aspect against the smart grinder pro, maybe you could share with us what is your brewing technique, beans etc etc.

I did not encounter any metallic taste with my EK43S, just a steep steep learning curve. :lol: :lol:

Never heard of EK43 making coffee metallic? Do you see actual metal pieces after you grind the coffee?

The problem using commercial brew grinders for home use: They take about 2 years to break in.

I was doing a pour over with my kalita wave and using a Costa Rican single origin from Verve. Fellow Stagg EKG is my kettle. The dripper was metal yes but the taste was fine with my breville — the grinder was the only variable changed.

There was no visible change to the coffee. It was just the taste. And smell. It also smelled like metal.

I certainly hope it doesn't take two years.

I don't ever recall getting a metallic taste in mine. I did see a large amount of the lubricant on the back of rotating burr carrier and chamber. More than I would have expected seeing other people's EKs.

Maybe try putting some Grindz and/or rice through it?

Is plain white rice the best variety?

I'm not sure - it might be best to ask Mahlkoening to make sure it doesn't void your warranty and such. I don't doubt something as powerful as the EK43 and the incredibly hard burrs will chew through any kind of rice/grain but you want to be careful with such expensive equipment.
