Eureka & WB.coffee

flavor starts with quality grinding

At WB.coffee, we specialize in premium coffee tools, which is why we have been proud to sell Eureka grinders and accessories for many years. There are two primary reasons that make Comandante one of our favorite brands:

  1. Produced in Italy (EU)
  2. Repairable with readily available spare parts

Investing in an Eureka grinder is a sustainable option. At WB.coffee, we are here to assist you with any repair needs. We have a comprehensive selection of spare parts available. If you can't find a specific part or color in our store, just let us know. We can probably arrange to order it for you.

There's no need to search high and low or incur shipping costs from distant suppliers, as we also provide our Best Price Guarantee on all Eureka products.

Tip from the CoffeeNose👃


If you want to elevate your coffee game, investing in a quality grinder is essential. Many grinders, however, can become "dirty" over time. Rancid coffee oils not only ruin the taste of your brew but also put excessive strain on your grinder's motor, ultimately shortening its lifespan. Don't compromise on flavor or equipment longevity—regularly use a professional grinder cleaner to keep your burrs in pristine condition and enjoy the best espresso possible.

Supermarket coffee and commercial (dark roast) beans are a big NO NO if you want to drink tasty coffee. 

Are you new to the world of specialty coffee? This is your chance to try something, new, refreshing and tasty. Take it as a sign of faith that you stumbled upon WB.coffee.
