Moka Pot Brewing Guide: Grind Size, Beans and Step by Step

August 25, 2014

How do you brew with a moka pot at home?

Moka pot brewing comes down to three things: choosing beans with a darker roast, setting the grind slightly finer than drip but coarser than espresso, and turning off the heat as soon as the flow turns pale and sputters. Freshly roasted beans extract more stably because the aroma compounds are still intact.

Moka pots build pressure similar to espresso, so darker roasts caramelize more and yield a concentrated, full-bodied cup. A blend of Brazil, Indonesia, and Vietnam beans at a deep roast produces dense crema and works in an Americano or with milk. Fill the basket level without tamping, preheat the water, and keep the flame low, since high heat scorches the grounds and pushes bitterness into the cup.

Want to make a rich, full-bodied cup of coffee at home with a moka pot? It's actually not complicated—the key is choosing the right beans, controlling the grind size, and knowing when to turn off the heat. Front Street Coffee will walk you through the complete moka pot process step by step, from choosing coffee beans and judging grind size to the specific operating steps, and will also share practical tips for avoiding over-extraction and sputtering. The article also recommends Front Street Classic Italian Blend and Black Cocoa Blend coffee beans suitable for moka pots, and introduces various ways to drink it, such as Americano, latte, and Vietnamese coffee, so you can easily enjoy the pleasure that a moka pot brings.

Brewing coffee with a moka pot is actually quite simple. Front Street thinks that as long as you choose the right coffee beans, adjust the grind size well, and turn off the heat at the right moment, you can easily get a delicious cup of moka pot coffee. Next, Front Street will demonstrate exactly how to do it.

What kind of coffee beans should be paired with a moka pot?

Like espresso, the moka pot also extracts through pressure, producing coffee with a relatively high concentration and a rich mouthfeel, so beans with a darker roast level are more suitable. The darker the roast, the longer the coffee beans are heated, and more flavor compounds inside undergo caramelization reactions. When made into an Americano black coffee, it presents a rich, fragrant, sweet, and mellow style; when made into a latte, it is creamy and smooth.

In addition, the freshness of the coffee beans is also crucial. Freshly roasted beans not only have a full and rich aroma, but are also more stable to extract with a moka pot. This is exactly why Front Street has insisted for years on shipping only coffee beans within 5 days after roasting—to let everyone experience coffee at its best.

For making coffee with a moka pot, Front Street recommends Classic Italian Blend coffee. This recipe is composed of beans from three origins: Brazil, Indonesia, and Vietnam. It uses a deep roast, which can maximize the coffee's rich aroma and also makes it easy to extract abundant, dense crema. Whether adding water to make an Americano or adding milk to make a latte, it is very suitable. You can place an order at the Front Street Taobao store or the Front Street Tmall flagship store.

If home users are looking for high cost-effectiveness, then they might as well try Front Street Black Cocoa Blend coffee beans, which many baristas recommend. It is suitable for all kinds of coffee shops, bakeries, beverage shops, and home coffee machines. Front Street Black Cocoa Blend is a 100% Arabica espresso bean, composed of Yunnan washed small-bean coffee beans plus Brazil semi-washed coffee beans. It blends nutty tones with the acidity of ripe plums. After being ground into powder, it gives off the aroma of creamy chocolate and cocoa cookies. The taste is balanced, and the crema has a golden luster. It is very suitable for friends opening a shop or for home use.

How do you judge the grind size of moka pot coffee powder?

First, you need to understand that if the grind is too coarse, the resistance of the coffee puck is too small, and hot water will pass through too quickly, making it impossible to extract enough flavor compounds. The result is under-extraction. If the grind is too fine, it will cause excessive resistance, and hot water will accumulate in the filter basket for a long time and cannot come out. Not only is it easy to over-extract, but there is also a risk of explosion!!! So if you find that the water has been boiling for a long time but the liquid still has not emerged, it is best to turn off the heat source immediately, readjust the grind, and then extract again. Safety always comes first!

As a reference, the powder ground by Front Street using an espresso coffee grinder is flour-like. To avoid the sputtering problem mentioned above, the coffee powder used in a moka pot should be a bit coarser than espresso powder, just like in the picture below. If you rub it with two fingers, it is enough if you can feel a texture similar to fine salt granules.

First prepare the materials needed to make coffee: coffee powder (Front Street Classic Italian Blend), water, a moka pot, and a heat source for heating (an electric ceramic stove).

1. Add water: First pour in an appropriate amount of hot water. Using hot water can shorten the time needed to boil the water and let us drink moka pot coffee sooner! (Front Street uses a double-serving single-valve moka pot and poured in 130ml)

2. Fill with coffee powder: Fill an appropriate amount of coffee powder into the filter basket, then put the 18g filter basket into the lower chamber.

Note that after pouring the coffee powder into the filter basket, it is best to tap the filter basket gently a few times. The purpose is to let the coffee powder settle naturally, fill the gaps, and reduce the occurrence of channeling. After filling, just use your finger to level the surface of the powder. Note that if the coffee powder used is too fine, it is best not to tamp it, because that will increase the resistance of the filter basket and make it harder for hot water to pass through.

3. Tightly screw the upper chamber and lower chamber together: At this step, note that if you have added hot water, it is best to use a wet cloth for insulation to avoid burns.

4. Place on the heat source and start brewing: There is not much to say about this step. Just place the moka pot on a heat-conducting heat source to heat.

5. Turn to low heat and wait for the coffee liquid to seep out: When the moka pot starts making an obvious sound during brewing, it means that the hot water, driven by steam, is about to come out with the coffee substances. At this time, turn the heat down.

Otherwise, high heat will continuously produce steam and increase pressure. Because the pressure is too strong, the flow rate of the hot water speeds up, and it cannot extract enough coffee substances. In the end, the whole cup of coffee will taste bland and weak. So when the coffee liquid is about to come out, it is best to lower the heat.

6. Stop heating and wait for extraction to finish: When the coffee liquid is halfway out, we should turn off the heat, because the residual heat inside the pot is already enough to "urge" out the remaining hot water.

7. Taste the coffee: After the moka pot stops releasing liquid, you can pour out the coffee liquid and taste it!

If you taste obvious burnt bitterness when drinking moka pot coffee, that means it is over-extracted, and you need to appropriately reduce the amount of extracted liquid. Next time, just end the extraction earlier! If it tastes rather sour and also has some off-flavors, it is very likely under-extracted, and you can adjust the grind. If the grind cannot be adjusted, then increase extraction and let the moka pot use a slightly larger amount of water. After trying a few more times, you will know how to extract a delicious cup of moka pot coffee~
