What Coffee Beans Are Suitable for Moka Pots: Advantages, Disadvantages, and Usage Steps

While espresso coffee is certainly delicious, not every household has the financial resources or space to own an espresso machine. Therefore, more people have moka pots at home. Moka pots are convenient and quick—you simply add hot water and coffee grounds, then place them on a heating device and wait for your coffee.

However, coffee brewed in a moka pot doesn't match the quality of today's espresso machines. The original purpose of the moka pot was to serve as a substitute for espresso machines. It's worth understanding that modern espresso extraction uses extremely high pressure to force near-boiling water through a compact coffee puck, and achieving such high pressure only became possible in recent times with the development of espresso machine manufacturing technology.

The History of Espresso Machines and Moka Pots

To understand the emergence of the moka pot, we must first discuss the history of espresso machines. The first espresso machine was showcased in Turin, Italy, at the end of the 19th century. By 1905, La Pavoni introduced the first commercial espresso machine, allowing baristas to serve espresso to multiple people quickly. Subsequently, more and more cafes across Italy began using La Pavoni machines.

This large commercial espresso machine required heating the entire device over a flame when making coffee. The machine's interior used internal steam to push hot water from the bottom compartment through a tube leading to the coffee grounds. However, this machine was prohibitively expensive and bulky—ordinary households couldn't possibly have such a coffee machine at home unless they were wealthy families.

The Birth of the Moka Pot

The moka pot emerged in the 1930s when Alfonso Bialetti from northern Piedmont invented this device. After working in the French aluminum industry for over 10 years, Bialetti returned to his hometown and established his own workshop producing aluminum household goods. One day, while watching his wife wash clothes, Bialetti had a sudden inspiration that led to the invention of the moka pot. At that time, washing machines were divided into two layers: the lower layer contained soapy water that was heated to boiling, while the upper layer held the clothes to be washed. A tube connected the two layers, allowing hot soapy water to flow upward and distribute over the clothes. With the help of Luigi De Ponti, the moka pot we know today was developed.

How the Moka Pot Works

The Bialetti moka pot operates on the same principle as the washing machine mentioned above. It features an octagonal aluminum pot with an insulated handle. The device consists of three main parts: the bottom chamber holds water, the top chamber collects the brewed coffee, and the middle section contains a metal filter for ground coffee.

To brew coffee with a moka pot, first fill the bottom chamber with a certain amount of hot water, add coffee grounds to the metal filter, then install the filter on the bottom chamber and screw on the top chamber tightly. Finally, place the entire brewing device on a heat source. When the water in the bottom chamber boils, it produces steam. Due to the limited space in the bottom chamber, as steam increases, so does the pressure, forcing hot water through a tube into the middle coffee grounds, then through pipes in the metal filter into the top chamber.

Differences Between Moka Pot and Espresso

The moka pot was created to replace the espresso machines of the late 19th and early 20th centuries. However, after decades of development, espresso machine extraction pressure far exceeds the early 1.5 bar. Additionally, because water moves upward through boiling, the water temperature is relatively high. This creates significant differences compared to espresso extracted by modern espresso machines. One of the pros and cons of moka pot coffee is its lack of rich crema. Modern espresso machines have extraction pressures far exceeding those of moka pots, meaning moka pot coffee has less crema than espresso machine coffee.

Furthermore, the reason for this characteristic lies in the moka pot's relatively coarse metal filter. Moka pot coffee requires coarser grounds than espresso machines. As grounds become coarser, the surface area between water and coffee particles decreases, resulting in less extracted material. This means moka pot coffee isn't as thick as espresso machine coffee.

Coffee Beans Suitable for Moka Pot

Many people want to make espresso at home and have equipped themselves with moka pots. This leads to the question: What coffee beans are suitable for moka pot brewing to produce delicious coffee? Since the moka pot was designed as an affordable alternative to early espresso machines, and espresso is characterized by its rich, smooth flavor, deeper roasted coffee beans are needed to achieve rich crema.

In addition to trying FrontStreet Coffee's Sunflower Warmth Blend, you can also try the Indonesia PWN Gold Mandheling coffee beans and Brazil Fazenda Rainha coffee beans from their bean list.

Indonesia PWN Gold Mandheling

Mandheling coffee beans originate from Sumatra Island, Indonesia, also known as "Sumatra coffee." Mandheling is a premium Arabica variety grown on highland plateaus at elevations of 750-1,500 meters. When it comes to Mandheling coffee, FrontStreet Coffee loves its intense aroma, full body, and strong flavor, while its unique herbal spice characteristics are also a hallmark of Mandheling coffee. In addition to Indonesia's growing conditions, the wet hulling processing method is one of the sources of Mandheling coffee's distinctive flavor.

Mandheling coffee typically uses Sumatra's unique wet hulling method. Due to water scarcity, Mandheling was originally processed mainly through natural drying, but this had the disadvantage of inconsistent quality. Later attempts were made with Brazilian semi-dry processing, but the local weather is predominantly rainy with frequent typhoons and constant humidity, making it impossible to achieve the weather conditions required for natural drying.

The local economy also has limitations, preventing the use of the more expensive washed processing method, which ultimately led to the development of the uniquely local wet hulling method. The wet hulling process is characterized by phased, rapid drying and hulling of parchment during drying. Teacher Han Huaizong describes it as "a rare processing method worldwide, which accidentally created Mandheling's special low-acidity, thick, and mellow flavor characteristics." In terms of roasting, to highlight Mandheling coffee's rich and intense characteristics, FrontStreet Coffee's roasters use a deeper roast level.

Brazil Fazenda Rainha

FrontStreet Coffee: Brazil Fazenda Rainha Coffee Beans
Region: Mogiana Region, São Paulo State, Brazil
Estate: Fazenda Rainha
Altitude: 1,400–1,950 meters
Variety: Yellow Bourbon
Processing Method: Natural Processing

The Yellow Bourbon variety was discovered in São Paulo State, Brazil, in the 1870s. Later scientific research found that Yellow Bourbon has a richer mucilage layer containing large amounts of sugars, giving Yellow Bourbon a more pronounced sweetness. FrontStreet Coffee's Yellow Bourbon coffee beans use the most primitive and traditional post-harvest processing method—natural processing. This method preserves the complete fruit skin and pulp, allowing more sugars to penetrate the coffee beans, achieving a qualitative leap in sweetness.

Fazenda Rainha has won multiple awards since the first Brazil Cup of Excellence competition in 1999, even winning 12 awards within 7 years, demonstrating the superior quality of coffee beans produced by this estate. Natural processing requires significant manual labor. To avoid undesirable fermentation flavors, Fazenda Rainha specifically uses small-scale natural processing to ensure green bean quality.

Alternative Brewing Methods

Those without moka pots at home might wonder: Can you make espresso with a French press? After all, the French press is one of the simplest coffee brewing tools, commonly found in homes. Making espresso with a French press, while it may not produce that beautiful golden crema, retains the coffee's original oils, offering its own unique flavor profile.
