Why is the grind size so important?
Before we delve into the details of each brewing method, we should understand why the grind size plays such a crucial role. The grind size of a coffee determines how finely or coarsely the coffee beans are ground. This fineness or coarseness of the coffee grounds directly influences how the water comes into contact with the coffee and how it flows through the grounds. This, in turn, affects the taste, aroma, and strength of your coffee.
Different types of coffee grinders:
Before we delve into the preparation methods, let's take a look at the different types of coffee grinders that affect the grind size.
- Hand grinders : Hand grinders are compact and user-friendly devices that allow you to control the grind size. Manufacturers such as Comandante and Hario offer high-quality hand grinders. Prices for these grinders typically range from €50 to €350, depending on the model and quality.
- Electric grinders : Electric grinders are efficient and ideal for those who grind a lot of coffee daily. Manufacturers like Mahlkönig offer professional electric grinders that allow for precise grind size adjustment. However, these grinders can be more expensive, typically costing between €300 and €2,000, depending on the model and features.
1. Portafilter Espresso
Espresso made with a portafilter is the most demanding method of coffee preparation and places high demands on the grind. In an espresso machine, hot water is forced through finely ground coffee under high pressure. A grind that is too fine can cause the water to flow through the coffee too slowly, leading to over-extraction and a bitter espresso. Conversely, a grind that is too coarse can cause the water to flow through the coffee too quickly, resulting in under-extraction and a sour or watery espresso. The ideal grind for espresso is often in the medium range, ensuring optimal extraction and a balanced flavor profile with a rich crema. In our regularly held barista course, you'll also learn the basics of adjusting your grinder.
2. Espresso maker (Moka)
The stovetop espresso maker, also known as a Moka pot, is a popular method for brewing espresso-like coffee on the stovetop. The grind size is crucial here as well. A grind that is too fine can create excessive pressure in the pot and even cause damage. A medium grind is ideal, as it allows for a balanced extraction and produces the characteristic espresso flavor of a Moka pot.
3. Filter coffee
Brewing filter coffee requires a medium to coarse grind. The coffee is slowly filtered through a paper filter, so the surface area of the coffee grounds should be large enough to ensure optimal extraction. A grind that is too fine can lead to over-extraction, which makes the coffee bitter. A medium grind, on the other hand, produces a clean and crisp cup of coffee with lighter aromas and a pleasant acidity.
4. French Press
The French press is known for its full body and intense aromas. Therefore, it requires a coarse grind. A grind that is too fine will allow small coffee grounds to pass through the filter and cloud your coffee. A coarse grind allows the coffee's aromas to develop optimally, resulting in a strong and aromatic cup of coffee.
Aromas and strength
The grind size affects not only the extraction but also the aromas and strength of your coffee. Finely ground coffee has a larger surface area and can deliver richer and stronger aromas. Coarsely ground coffee, on the other hand, produces a lighter and less concentrated coffee. If you love discovering different aromas and flavor nuances in your coffee, you should experiment with different grind sizes.
