A coffee grinder is an essential piece of equipment for coffee enthusiasts, allowing them to grind coffee beans to various degrees of fineness, providing a crucial tool for making delicious coffee. With the popularization of coffee culture and the emphasis on coffee quality, there is an increasing demand for coffee grinders that can provide precise grinding results to ensure the best possible taste and aroma of coffee.

The Krups GX550850 burr coffee grinder allows you to freshly grind coffee beans to unlock maximum flavor and aroma. With 12 grind settings to choose from, this versatile grinder can produce grinds ideal for drip, French press, espresso, pour over, cold brew, and more.


The Krups GX550850 features premium metallic flat burrs that grind coffee beans uniformly for consistent particle size and optimized extraction. It has 12 major grind settings with micro-adjustments to fine-tune grind size from extra coarse to super fine.

The grinder is equipped with a powerful 110W motor and 8oz bean hopper. Its grounds container can hold enough ground coffee to brew up to 32 cups. Convenient features include a 2-12 cup selector, auto stop, and built-in cleaning brush.

Key Features

  • 12 grind settings
  • 8oz bean hopper capacity
  • 32 cup ground coffee capacity
  • Removable ground coffee bin
  • Built-in cleaning brush

Working Principle and Advantages

Coffee grinders operate by grinding coffee beans into different degrees of fineness using rotating burrs. The advantage of using flat burrs is that they ensure uniform grinding, providing a more consistent grinding result. Compared to blade grinders, flat burr grinders typically produce fewer fines, thus improving the quality and taste of the coffee.

Design and Build Quality

The GX550850 has a sleek all-black plastic exterior with stainless steel accents. The burrs are made of strong, durable metal. The grounds bin, while convenient to remove, is plastic and prone to static cling.

Ease of Use

Using this grinder is very straightforward. Just pour beans in the hopper, select grind setting and number of cups, and press the power button. I like that it stops automatically when done grinding. Cleaning is easy with the built-in brush.

Grind Settings

A major highlight of this grinder is the wide range of grind sizes it can produce. The 12 settings go from extra coarse for cold brew to super fine for espresso. I found the micro-adjustments between settings allowed me to really dial in the perfect grind.

Grind Consistency

The flat burrs produce impressively consistent grinds. I tested everything from French press to espresso and was pleased with the uniform particle size. Fines are minimized, though not completely eliminated.

Brew Performance

I’ve been getting great flavor from pour over, French press, and Aeropress using this grinder. The espresso grind is passable but not quite fine enough for optimal extraction. Those looking to upgrade from blade grinders will notice a marked improvement in coffee quality.

Noise Level

It produces a moderate noise level comparable to an average countertop blender. The sound itself is not irritating, but some may prefer to grind coffee before brewing to avoid the noise early in the morning.

Maintenance and Care Tips

To ensure the proper operation and longevity of the coffee grinder, it is recommended that users follow these maintenance and care tips:

  • Clean the grinder’s burrs and container promptly after each use to prevent coffee grounds residue.
  • Regularly inspect the burrs for wear and tear, and replace them promptly if worn to maintain grinding effectiveness.
  • Use specialized cleaning agents to clean the grinder’s interior regularly to keep it clean and hygienic.
  • Avoid putting damp coffee beans into the grinder to prevent rusting and corrosion.

By following proper maintenance and care practices, users can prolong the lifespan of their coffee grinder and ensure the quality and taste of their coffee.

The consistency and range of grind sizes are consistently praised. Many users mention taste and aroma improvements after switching from blade grinders. They appreciate the ability to fine tune the grind for optimal flavor extraction.

A common complaint is static cling and messiness with the plastic grounds bin. Some report grinds sticking to the bin walls and minor leaks when removing it. This may be alleviated by spraying bins with anti-static spray.

Several users warn the espresso setting does not produce a fine enough powder for ideal espresso extraction. They recommend stepping up to a dedicated espresso grinder for best results. However, the espresso grind is suitable for moka pots and aeropress.

In reviews, the grinder is described as easy to use and clean. The automatic stop and built-in brush are convenient features owners appreciate. Some note the noise is moderate but not intrusive.

Overall, feedback indicates the Krups burr grinder performs very well for French press, pour over, cold brew, and drip methods. It provides significantly improved grind consistency over cheap blade grinders. For the affordable price, most agree it is an excellent value.
