Mahlgrad-Siebtraeger-SIMON&BEARNS

Using a portafilter machine is almost like a choreographed dance – every movement of the barista must be precise to produce an outstanding espresso. A crucial element in this complex sequence of movements is grinding the coffee grounds with a coffee grinder. But how do I know that the coffee has the right grind? What's the right grind setting for your portafilter ? In this article, we'll explain what's important and what you should pay attention to in order to set the perfect grind for your portafilter. Enjoy reading!

Why is the correct grind size so important for portafilter machines?

The grind size for portafilter machines refers to the fineness or coarseness with which the coffee beans are ground. This is particularly critical when preparing espresso with a portafilter, as the grind size determines and influences the extraction time and therefore the flavor profile. A grind that is too fine can lead to over-extraction, resulting in a bitter and burnt-tasting espresso. Conversely, a grind that is too coarse leads to under-extraction, and your coffee will taste acidic. It can even lead to channeling – water, as we know, tends to take the path of least resistance and therefore doesn't flow through the entire coffee grounds. The espresso will taste watery.

The secret to the perfect grind for portafilter machines

The secret, indeed almost the art, of setting the correct grind for an espresso machine lies in achieving the balance between fineness and coarseness of the coffee grounds. This balance is only achieved through much practice, experience, and a good eye for detail. The rule of thumb is that the coffee grounds for an espresso machine should be ground finely enough that the extraction time is 25-30 seconds.

Tips for setting the correct portafilter grind

To find the perfect grind for your espresso machine, you'll need to experiment a bit. So grab your favorite coffee, turn on the grinder, and get a scale and timer ready. Then follow our tips:

1. Start with a medium grind and gradually work your way up from there.

2. Observe the extraction time.

If your espresso takes less than 25 seconds to brew, the grind is too coarse. If it takes longer than 30 seconds, the grind is too fine.

3. Pay attention to the consistency.

Upon closer inspection of your ground coffee, it should resemble fine sand. However, excessively fine powder can clog your portafilter. Conversely, excessively coarse powder will cause the water to flow unevenly through the portafilter.

4. Experiment!

Once you've found the perfect coffee setting for you, it's possible that it won't taste right with a different coffee. Therefore, check and adjust your settings slightly with each new coffee.

Frequently asked questions about the perfect portafilter grind

Can I use the same grind setting for all types of coffee?

Absolutely not! Different coffee varieties require different grinder settings. So experiment a little with each new variety and test which grind size is optimal for you.

Can the grind size vary from time to time?

Of course! Coffee is a craft with a "living" product, and factors like humidity, temperature, storage times, and much more affect the green coffee and can change the properties of the bean. All of this can necessitate an adjustment of the grind size.

How often should the grind setting of the portafilter be checked?

Especially with new coffees, the grind size should be checked immediately. And even with your favorite coffee, you should regularly test the grind size and adjust it if necessary.

Conclusion:

With a little patience and a willingness to experiment, finding the ideal portafilter grind is quite simple. Even if it seems challenging at first, every little adjustment on the way to the perfect espresso is worthwhile. So take your time to thoroughly test the different settings of your coffee grinder and portafilter and learn which buttons to press for optimal results.
