As a symbol of Italian coffee culture, the moka pot is one of the most famous brewing devices in the world. Its iconic design, ease of use, and wide applicability make it the starting point for many enthusiasts learning about coffee. Today, Front Street Coffee brings the moka pot commonly kept in stores to give everyone a proper introduction to this coffee equipment and how to use it.
Unlike other brewing devices, the moka pot is a device that extracts rich coffee through heating and pressure. It was invented in 1933 by the Italian Alfonso Bialetti and is mainly popular in European countries, especially in its birthplace, Italy, where the vast majority of households have a moka pot at home.Traditional moka pots are made of aluminum alloy and can only be heated over an open flame. Nowadays, most on the market are made of stainless steel and can be placed directly on an induction cooker for coffee extraction. When purchasing, we can also choose different sizes of moka pots according to our needs, with the most common being the compact 2–3 serving size.
From the picture, we can see that the moka pot is divided into upper and lower structures, mainly composed of three parts: the upper chamber that holds the coffee liquid, the filter basket that holds the coffee grounds, and the lower chamber that holds water. When using a moka pot to extract coffee, a heat source is used to heat the water in the lower chamber to generate steam pressure. Once the pressure is sufficient, it pushes the hot water upward, seeps through the coffee grounds to bring out soluble aroma compounds, and continues upward to produce a rich and mellow coffee liquid. When drinking, simply add water or milk according to your preference.
Before extracting coffee, you need to prepare a bag of coffee beans at their optimal flavor period, a gas stove or induction cooker for heating, a grinder for grinding coffee beans, and water. In order to showcase the crema of moka pot coffee, Front Street Classic Italian Blend (Brazilian coffee + Indonesian Mandheling coffee + Vietnamese coffee) is used here. This coffee uses a medium-dark roast, and the extracted strong coffee has a thick body, suitable for adding milk to make a latte. The electric ceramic stove used for heating,the grinder isthe EK43s used for store output.
The grind size for a moka pot is generally slightly coarser than espresso powder, and much finer than pour-over. If the grounds are ground too coarse, the contact area between water and coffee grounds is smaller, which will not only lead to insufficient extraction and a weak taste, but also cause the liquid to gush out because the resistance to upward flow is too small, posing a risk of splashing and scalding. Front Street recommends a coarseness of EK-43s #3-3.5 setting, which feels finer than fine granulated sugar.
1. Add hot water to the lower chamber, keeping the water level controlled to about 0.5 cm below the pressure relief valve (safety valve). Front Street has measured that the water amount at this position is about 100 g, and when the coffee grounds are leveled in the filter basket at about 20 g, the coffee-to-water ratio will be around 1:5. Note that using cold water will increase the soaking time of the coffee grounds and cause over-extraction and bitterness, so Front Street recommends using hot water, which can also shorten the extraction time.
2. The grind size of the coffee grounds needs to be finer than pour-over coffee and coarser than espresso. You can refer to the size of the filter basket mesh openings to ensure the coffee particles are filtered out. Pour the coffee grounds gently into the filter basket and use your finger to tap and level them evenly.
3. Put the filter basket back into the lower chamber, tighten the upper chamber, place it on the electric ceramic stove and start heating, waiting for the moka pot to heat up.
4. When you hear a hissing sound from inside the moka pot, turn the stove to low heat and open the lid of the upper chamber. At this point, you can see the coffee liquid and crema slowly flowing out.
5. When the coffee liquid in the upper chamber is half full, you can turn off the heat source and move the pot to the table, using the residual heat and pressure inside the pot to continue extracting the remaining coffee liquid. It should be noted that the moka pot uses metal parts, so try not to touch the body when it is heated at high temperatures to avoid burns.
6. The finally extracted coffee liquid can be tasted directly, and the taste will be very rich and strong. You can appropriately pair it with milk or other mixtures according to your preferred taste. The moka pot coffee extracted from Front Street Classic Italian Blend beans has a rich caramel aroma, almond and chocolate notes, and a dark cocoa aftertaste. Paired with heated milk to make a milk coffee, it presents a dense, sweet, and creamy chocolate texture.
If you want the espresso extracted from a moka pot to have a rich, aromatic crema layer, Front Street recommends using freshly roasted medium-dark roasted coffee beans. As the roast level deepens, coffee beans undergo caramelization and produce a large amount of gas, which is released under pressure during extraction. As storage time lengthens, the beans lose a large amount of gas, making it difficult to extract a rich, aromatic crema. The coffee beans shipped by Front Street are all freshly roasted within 5 days, so everyone can enjoy them during their optimal flavor period.
