The moka pot is one of the earliest household coffee brewing devices ever invented. It is a short-time, high-pressure extraction device, and the coffee it produces is espresso.Moka Pot CoffeeIt is also very simple to operate, satisfying both our nostalgia for the retro and our coffee needs. However, the moka pot can sometimes produce bitter, overly strong coffee with insufficient flavor. So how do we solve these problems? Today, let's analyze this from the aspects of bean selection, brewing, and tasting.

 

1. Try fresh medium-dark roasted coffee beans

 

Because the moka pot uses pressure-based extraction, it tends to amplify the flavors of the beans themselves, sometimes even turning them into flaws. If you use light-roasted coffee beans in a moka pot, the resulting coffee will have thin crema and be intensely sour, and adding water or milk may also taste strange.

Medium-dark roasting, on the other hand, brings more caramelization reactions to the coffee beans and produces more gas. If you want to make moka pot coffee with a balanced taste, full body, and crema, it is recommended to choose fresh medium or medium-dark roasted coffee beans.


There are many types of coffee beans suitable for moka pot use, which can be roughly divided into blends and single-origin coffees. Single-origin coffees allow you to taste distinct regional flavors, while blends offer higher value for money and can serve as everyday staples.

2. Use a sufficient amount of coffee grounds

 

How do you tell if the coffee grounds are filled to the top? You can do it this way: fill the empty filter basket of the moka pot with coffee beans, then pour the coffee beans from the empty basket into the grinder to grind, and finally pour all the ground coffee into the basket. If some grounds won't fit, you can tap the basket on the table to make sure the rest of the grounds go into the basket.

Filling the basket to the top is also about avoiding the extraction of unpleasant defective flavors. This is because the closer the density of the coffee grounds in the basket, the less likely it is that some grounds will be over-extracted or some under-extracted, which would lead to uneven flavor or bitterness. If every particle of coffee grounds can be extracted evenly and just right, the flavor of the cup will be more complete with fewer defects.

 

3. Testing the grind size

 

We all know that one important thing in making coffee is nailing the grind size of the coffee beans, and this is also the issue everyone agonizes over the most. What exactly is the right grind size? How many notches should I set my grinder to?

The moka pot is designed for high-temperature, pressurized extraction, so the coffee itself will be richer overall. Therefore, you cannot grind as fine as espresso, otherwise it will easily clog or over-extract and develop bitterness. Of course, don't grind the coffee too coarse either, otherwise the mouthfeel will be thin, the flavors will be lost, and only bitterness will remain—a waste of both the beans and the equipment. We can refer to the gaps in the filter basket: as long as the grounds don't fall through, grind as fine as possible to meet the extraction requirements. When you first start learning to use a moka pot, you may need to try several times before finding the knack, so don't get discouraged.
