Manual coffee grinders typically feature burr grinders, which consist of two abrasive surfaces (burrs) that grind the coffee beans. However, improper burr adjustment can lead to a variety of problems in terms of grind consistency and quality. Here are three common mistakes to watch out for:

Setting the burrs too close

When the burrs are set too close together, the grind size becomes too fine, resulting in over-extraction and a bitter taste. This mistake is often made by coffee enthusiasts who chase after an ultra-fine grind for their espresso shots. However, by setting the burrs too close, you risk turning your coffee into a sludgy mess and compromising the flavor profile. It’s important to find the right balance and avoid the temptation of pushing the burrs too close for an even finer grind.

Setting the burrs too far apart

On the other hand, setting the burrs too far apart can result in a coarse grind that lacks consistency. This mistake is often made by those who enjoy brewing methods such as French press or cold brew, which require a coarser grind. By not adjusting the burrs properly, you may end up with inconsistent particle sizes, leading to uneven extraction and a subpar cup of coffee. Taking the time to find the optimal setting for your desired brewing method is essential for achieving the best possible flavor.

Inconsistent grinding

Inconsistency in grind size is a common issue when the burrs are not properly adjusted. This mistake can occur when the burrs are loose or not securely placed, leading to uneven grinding. Inconsistent grinding can result in both over-extraction and under-extraction during brewing, leading to an imbalanced and less enjoyable cup of coffee. It’s crucial to ensure that the burrs are properly aligned and tightened to achieve a consistent grind size.

Grinding Too Fast or Slow

The speed at which you grind your coffee beans can also significantly impact the flavor and extraction of your final cup. Here are three common mistakes related to grinding speed:

Grinding too fast

Grinding too quickly can generate heat and friction, which can negatively affect the flavor and aroma of your coffee. When the beans are ground at a rapid pace, the heat produced can cause the volatile compounds in the coffee to evaporate, resulting in a loss of flavor. Additionally, fast grinding can lead to a more inconsistent grind size as the beans are not given enough time to be properly processed. To avoid these issues, it’s important to take your time and grind at a moderate speed, allowing for a more controlled and flavorful extraction.

Grinding too slow

While grinding too quickly can be detrimental, grinding too slowly can also have negative consequences. When the grinding process is excessively slow, the beans can become overheated, leading to a burnt or bitter taste. Moreover, slow grinding may result in an inconsistent grind size as the beans are subjected to extended contact with the burrs. It is crucial to find the right balance and maintain a moderate grinding speed to ensure optimal extraction and flavor.

Not adjusting the speed

One of the advantages of manual coffee grinders is the ability to control the speed at which you grind. However, many people make the mistake of sticking to a single speed without considering the specific needs of their coffee beans and brewing method.
