Calibrate your coffee grinder for better-tasting coffee



If you love to brew your own coffee, you know that grinding beans is an important step in ensuring a perfect cup. More importantly, the coffee is ground evenly. Uniformly sized surfaces are crucial for the preparation of excellent coffee.

Unfortunately, even the most unusual coffee mills can yield a mixture of particle sizes. This unevenness destroys the ideal taste of your sude and ultimately hampers its potential taste.

But do not lose heart. In this guide I offer you an easy way to test and calibrate your coffee grinder at home to get the most out of it.

And if you suspect that your old hustler no longer grinds like you used to, you're in luck. These steps will also confirm that.

Even fancy coffee grinders with burrs are a reason for mixed particle sizes.

Why the Uniformity of Milling Is Significant

The magnitude of uniform grinding may be a bit different for coffee nerds than if they were obsessed. If you love good Joe, it's not a trivial matter.

Let's say you have an excellent coffee maker and freshly roasted coffee beans. Now connect this to a mediocre mill. The drinks you brew may not be bad. They can even be pretty good. But to get the ultimate aroma from your beans, you have to do better.

The reason lies on the surface. Finer reasons have more, bigger bits have less. So water extracts coffee compounds from fine soils faster than coarse ones.

This leads to an uneven extraction. Fine, coated bottom increases the bitterness of the brewed coffee. Large, undervalued facilities give the party a faint taste and a bad acidity.

With the Kruve Sifter you can find out how well your grinder processes coffee beans.

Step 1: Collect your tools

You need two tools for this project. The first is an ordinary kitchen scale. You may already have one. Usually about $ 20, they are relatively cheap if you do not.

The second article, the Kruve Sifter Two (49 Euro), consists of two stainless steel sieves and three inner compartments. It is the base model for the overflow. Yes, that's a pretty specific tool, but you'll see why.

Make sure you also have some coffee beans handy. Finally, hold your coffee grinder within easy reach, as you want to use it.

Start with a rough shot and then work your way to finer grind sizes.

Step 2: Weighing and grinding

First, weigh out 10g of coffee beans. Next, adjust the coarseness of your grinder. Start with the coarsest setting that is within the recommended range for your brewing method.

In my case, I used the Baratza Encore ($ 139 at Amazon) which is set to 15 (0 to 40). At this point, it is a good idea to record the weight of each Kruve section (including the screens, but not the lid). That makes life easier later.

Now grind the coffee and drop it into the top of the kruve.

Drop your terrain onto the top of the Kruve sifter.

Step 3: Browse the Terrain

The next step is to sift through your terrain. When the ground coffee is in Kruve, replace the lid. Shake the device horizontally for 60 to 75 seconds.

Be sure to tap regularly on the sides of the Kruve during the process. This helps to remove coffee grounds that could adhere to the interior walls of the compartment.

With the right attitude, your mill will create a reason that stays in the middle section of the Kruve.

Step 4: Analyze the Product

Carefully place the Kruve on a flat surface, remove the lid, and separate the chambers. You should see that the Kruve has sorted your terrain in three sizes. Rough areas are in the upper area, medium areas in the middle and fine particles have landed below.

What distinguishes the reasons are the two screens, which differ in porosity. Small particles pass through the first sieve (800 μm). The smaller areas still move through the second (400 microns). Ideally, you want most of your property to land in the middle chamber.

If your grinder is set for the right level of roughness, most of your equipment will be in the middle chamber and you will have a small, equal amount of fine and coarse surfaces.

Confirm by weighing each Kruve chamber (which still contains sieve and soil). From each value, subtract the weight of the empty chamber (which you previously recorded). This will give you exact quantities without having to transfer ground coffee to another container.

Step 5: Adjust and Repeat

It is likely that you will get an amazing result the first time you try it. For example, you could have more rough reasons than medium or fine. Or you have too many finely ground coffees and not enough medium. In this case, you must set the milling stage for a finer meal. Then repeat the process until you succeed.

There may be problems where your mill creates unbalanced proportions regardless of its setting. If so, you probably have a bigger problem – worn burrs. In that case, you probably need to buy new burrs from the manufacturer of your mill. Another possibility is to send the device to the factory for repair. And if everything else fails, you can always buy a brand new .
