Grinding coffee for the Newton BRUA.

If you're a fan of espresso, you know that the quality of the coffee beans and the brewing process can greatly affect the taste of your daily cup. While some people opt for automatic espresso machines, many coffee enthusiasts prefer to take a more hands-on approach by using a manual espresso maker.

One crucial step in the manual espresso brewing process is grinding the coffee beans to the right size and consistency. In this blog post, we will explore the importance of grinding coffee for manual espresso and share tips for achieving the perfect grind.


Manual  vs. electric coffee grinders 

Coffee enthusiasts have long debated the merits of electric versus manual coffee grinders. While both types of grinders can produce a fresh and flavorful cup of coffee, there are some key differences to consider. 

Electric coffee grinders are typically faster and more efficient than their manual counterparts. They use a motor to turn the burrs or blades, which can grind coffee beans in just a few seconds. This makes electric grinders ideal for busy mornings when you need to make coffee quickly.

On the other hand, manual coffee grinders require a bit more time and effort to use - approximately 1 minute to grind 16 grams of coffee. These grinders have a hand crank that you must turn to grind the beans. While this may seem like a hassle, many coffee aficionados prefer manual grinders because they offer more control over the grind size and the flavor of the coffee.

Another advantage of manual coffee grinders is that they are often more affordable and portable than electric grinders. They don't require electricity, so you can use them anywhere, whether you're camping, traveling, or just enjoying a lazy morning at home - perfect when using a manual espresso maker.

Ultimately, the choice between an electric and manual coffee grinder comes down to personal preference. If you prioritize speed and convenience, an electric coffee grinder may be the better choice. But if you enjoy the process of making coffee and want more control over the final product, a manual grinder may be the way to go.

Getting the grind size right

Getting the right coffee grind size for espresso is crucial to achieving a balanced and flavorful shot. The ideal grind size for espresso is fine enough to create resistance during extraction, but not so fine that it clogs the machine. A good starting point is a grind size that resembles table salt. However, it's important to note that different machines and beans may require slight adjustments in the grind size. It's recommended to experiment with different grind sizes and fine-tune as needed to achieve the desired taste and texture of the espresso shot.

Common mistakes when grinding coffee beans

One of the most common mistakes people make when grinding coffee is using the wrong grind size for their brewing method. For example, using a fine grind for a French press can result in over-extraction and a bitter taste. Another mistake is not adjusting the grind size based on the freshness of the beans.

As coffee beans age, they become more brittle and require a coarser grind to avoid uneven extraction. Finally, people often forget to clean their grinders regularly, which can leave lingering coffee oils and affect the flavor of future batches. By avoiding these common mistakes, you can ensure a better cup of coffee every time.


In conclusion, the brewing process for manual espresso requires attention to detail, especially when it comes to grinding the coffee beans. Electric grinders offer convenience and speed, while manual grinders provide more control and portability. Getting the right grind size for espresso is crucial to achieving a balanced and flavorful shot, and it may require some experimentation. Finally, common mistakes such as using the wrong grind size, not adjusting for bean freshness, and neglecting to clean the grinder can all impact the taste and quality of the coffee. By keeping these tips in mind, you can elevate your coffee game and enjoy a delicious cup every time.
