Not adjusting grind settings is a mistake that can negatively affect the quality of your coffee or espresso. Failing to tailor the grind size based on factors like bean type, roast level, and brewing method can result in under- or over-extraction, leading to a subpar beverage experience.

Different beans and roast levels require specific grind sizes to achieve optimal extraction and flavor. For example, darker roasted beans typically need a coarser grind, while lighter roasts require a finer grind. Similarly, various brewing methods, such as espresso, pour-over, or French press, call for different grind sizes to ensure proper extraction and taste.

To make the most of your Grind by Weight grinder and consistently create delicious coffee or espresso, it's essential to adjust the grind settings as needed. Familiarize yourself with your grinder's adjustment mechanism and experiment with different settings to find the perfect grind size for your beans and brewing method.

By taking the time to fine-tune your grinder settings, you'll unlock the full potential of your GbW grinder and enjoy a consistently satisfying coffee or espresso experience.

Inconsistent tamping 

Inconsistent tamping is a common mistake that can have a significant impact on the quality of your espresso. When you apply uneven pressure while tamping the espresso grounds, it can cause channeling, which is when water flows through the coffee puck unevenly. This leads to imbalanced extraction and ultimately affects the flavor and consistency of your espresso.

To prevent channeling and ensure a properly extracted espresso, it's essential to practice consistent tamping techniques. Here are some tips to help you achieve even tamping:

  1. Use a level surface: Ensure your work surface is level and stable to help maintain consistent pressure while tamping.
  2. Distribute grounds evenly: Before tamping, distribute the coffee grounds evenly in the portafilter to create a uniform surface.
  3. Apply even pressure: Press down on the tamper with equal force, using your body weight for leverage. Some tampers have built-in pressure indicators to help you gauge the correct amount of force.
  4. Keep the tamper level: As you press down, ensure the tamper is level with the portafilter to create an even coffee puck.

By mastering consistent tamping techniques, you'll make the most of your Grind by Weight grinder's precision and enjoy a well-extracted, delicious espresso every time.

Rushing the process 

Rushing the process is a mistake that can undermine the accuracy and performance of your Grind by Weight grinder. Not allowing the grinder enough time to fully weigh and dispense the desired amount of coffee can lead to inaccurate dosing, which in turn affects the consistency and taste of your coffee or espresso.

GbW grinders are designed to provide precise dosing based on weight, ensuring optimal extraction and flavor. To fully take advantage of this feature, it's essential to give your grinder sufficient time to weigh and dispense the coffee grounds accurately.
