How to Make Your Own Espresso - 5 Mistakes to Avoid

0 commentPost by : Jasmin Tétreault

Are you contemplating the purchase of a home espresso machine or have you already procured one but are struggling to attain a barista-quality espresso from the comfort of your abode?

The taste of espresso, with its well-balanced and nutty coffee flavor, coupled with a velvety finish, is undeniably scrumptious. Alas, achieving the perfect cup can be rather tricky, and nothing is more exasperating for a coffee aficionado than purchasing top-notch coffee beans and brewing an inferior espresso shot.

In such a scenario, it may be due to one of the five mistakes enumerated below, leading to substandard shots. As a result, let us explore these mistakes collectively to enable you to rectify them and savor the delightful espresso cup you yearn for.

Using The Wrong Grinding Practices 

Grinding coffee sounds pretty straightforward, right?

Take a few coffee beans, throw them in your grinder hopper, press the magical button, and tada; you’re left with incredible coffee aromas filling the air and a deliciously brewed cup of coffee.

If only it was that simple!

One common mistake people make is to start grinding with the beans already inside the burr. Now, it might not seem like a big deal, but it is. That’s because it will affect the particle size distribution and, therefore, affect the extraction process. 

Your goal when brewing coffee should be to achieve even extraction, meaning the coffee particles should all be the same size or as close as possible. Now, I could spend hours explaining how this process works, but to make things simple, when coffee particle sizes aren’t as close as possible to even, your coffee will have an unbalanced taste. The coarser coffee particles won’t have a chance to be extracted properly, leading to sour flavors, while the finer coffee particles will have experienced over-extraction leading to bitter flavors. And when these two are mixed in a cup of Joe, the taste isn’t great!  

To achieve even extraction, you need to ensure consistency in the revolution per minute your grinder operates. Any inconsistency in the rpm (revolution per minute) during grinding will result in less uniformity of the particle size distribution and negatively affect the taste of your coffee.

Starting the grinder with beans already in the burr will result in a wider particle size distribution because the beans will be ground at a slow rpm until it reaches the faster final rotation rate.

Now, the great news is that there’s an easy fix; single-dose your coffee and turn on the grinder before grinding your coffee beans. 

Problem solved.

Using Water With The Wrong Mineral Balance 

Let us first address a crucial point before we delve into the significance of attaining the proper mineral balance for your espresso. It is imperative to refrain from utilizing flavored water, as it can drastically alter the flavor profile of your coffee. While this may appear self-evident, I believe it is worth emphasizing.

When it comes to crafting a delectable espresso, water plays an indispensable role since it comprises one of the only two elements in the beverage. This is precisely why the use of high-quality water is paramount in ensuring that you can relish a perfectly brewed cup each morning. Unfortunately, the utilization of water with an unsuitable mineral balance can mar the flavor of your espresso, rendering it an unpalatable experience.

You need well-balanced water. Why is that? 

Because water too low in minerals will prevent proper extraction of the powerful coffee flavors from the beans. Conversely, if your water is too high in minerals, it will prevent the aromas from developing the way they should and give your coffee a bad aftertaste. And it will also damage your coffee machine. 

Without getting too much into details into water composition, the bottom line is that water alkalinity and water hardness can both impact the taste of an espresso so you need to ensure the water you use is well balanced for a sweet and round acidity.

Using Coffee That’s Too Fresh Or Too Old

It may come as a surprise, but when it comes to making espresso, the ideal beans to use are those that have been freshly roasted 5-6 days prior. Moreover, proper storage techniques can keep these beans fresh for up to 5 weeks. If you're on the lookout for premium roasted coffee from some of the best roasters in the nation, then you've come to the right place!


Improper Burr Alignment

Sweet, you just bought a new grinder! But guess what? Chances are your brand-new grinder is imbalanced, as new grinders are not always perfectly calibrated from the factory.

The thing is, if your burrs are misaligned, you will end up with an uneven grind, which, as you know by now, will affect the flavors of your espresso. That’s because you will widen the particle size distribution. A simple realignment will make a difference.

Wrong Brew Ratio 

Ever purchased fantastic coffee beans and threw them in the grinder, ready to enjoy a delicious espresso, only to end up with a coffee that tastes sourer than lemon after a tequila shot?

Rather disappointing when you’re expecting dark chocolate and caramel flavors! 

We’ve all been there.

This most likely means that your brew ratio is off. When that happens, your espresso will either be too weak or too strong. The traditional espresso should have a 1:2 ratio of coffee to water. And as a rule of thumb, it should come out in 25-30 seconds.
