11 Common Moka Pot Mistakes (and How to Avoid)

For every coffee lover, chances are you’ve used Moka Pot or heard of it at least once. This traditional Italian coffee maker has been around for decades and has been a staple in many households. But during brewing, you can make mistakes that can affect the Moka pot coffee.

Your brew may have turned out bitter or over-extracted, or your Moka pot may simply not function properly if you don’t avoid those mistakes.

Fear not; with this article, you will easily understand what you’re doing wrong. Let’s see 11 common Moka pot blunders and how to avoid them.

Common Moka Pot Mistakes To Avoid

It is easy to make mistakes with a Moka pot. Nevertheless, with a few simple tweaks, you can consistently produce the greatest cup and avoid these issues. Here are the eleven most common errors and how to fix them like a master.

1.     Don’t Overfill Your Moka Pot Water Chamber

Recognize that the secret to a good cup of coffee is the proper amount of water. If you overfill your Moka pot, your brew may taste weak or sour. Moka pot works on steam pressure. The air above the water chamber expands and pushes the water to flow into the upper chamber.

So, if you overfill the water chamber, less air will be there, and therefore enough pressure will not be generated. That can result in Moka pot sputtering. Additionally, overfilling the pot might cause water to pour out, creating a mess and perhaps causing burns

Conversely, adding too little water or half-filling the water chamber might result in bitter and burned coffee. So how do you obtain the proper quantity of water?

How to Avoid This?

To avoid overfilling, make sure to always fill the water chamber just below the lower end of the safety valve. This is the optimum water amount & Moka pot is designed to work with that water level.

2.     Not Selecting the Right Grind

One of the most common Moka pot blunders is choosing the improper grind size. The Moka Pot requires a medium-fine grind, which is far finer than what you would use for a French press or drip coffee maker. Employing the incorrect grind size might result in coffee that is either weak or bitter, and also can end up with sediments in your cup.

How to Avoid This?

To avoid this mistake, make sure to use medium-fine ground coffee. It’s best to grind your beans right before brewing. If you’re not sure which coffee grinder will be perfect for the Moka pot, I suggest you read this article where I’ve listed a few good grinders for the Moka pot.

3.     Not Preheating the Water

Preheating the water is an important step. You can brew with cold water. But some coffee experts like James Hoffmann recommend pouring boiled water into the water chamber.

Also, a simulation run a physicist Warren King also states that cold water extract coffee at too low a temperature.

Additionally, he mentioned that boiled water will extract coffee at too high a temperature than the ideal brewing temperature which is 195~205 °F. According to his experiment, 70°C is the ideal preheating temperature for water.

I’ve also experimented with my Moka pot adding different temperatures of water; cold, boiled, and 70°C preheated water. I found the coffee brewed at 70°C is the best in terms of flavor, aroma, crema, and strength.

How to Avoid This?

If you have a thermometer use that to measure water temperature. If you don’t have, boil the water, and then add some cold water to reduce the temperature.

4.     Setting Up the Stove Too Hot

If the temperature of the burner is set too high, the coffee will likely be scorched and of poor quality. This occurs as a result of the stove’s high heat, causing extreme bitterness.

The water rushes through the grounds too rapidly, minimizing the time spent in contact with it and resulting in coffee that lacks flavor.

How to Avoid This?

The optimal setting for the Moka Pot is medium-high heat, which allows the coffee to flow freely without exploding. If you have an electric stove, you should preheat the burner for 30 seconds before placing the pot on it.

5.     Rushing The Brew

One silly mistake we all make is rushing the brew. Making coffee is an art in itself; it requires slow and steady brewing. Rushing it can result in an over & under-extracted cup of coffee.

How to Avoid This?

To avoid rushing the brew, make sure to keep an eye on the pot while it’s brewing. The process should take around 5-10 minutes. It all depends on the size of your Moka Pot, the water temperature, and the stove heat.

Resist the urge to turn up the heat or take the pot off the stove early. As this will affect the flavor of the coffee.

6.     Not Cleaning the Moka Pot Properly

Cleaning your Moka Pot is important to ensure that it lasts for years to come and that your brew tastes great every time.

Not cleaning the pot properly can result in a buildup of coffee oils and residue. In addition, it can also lead to Moka pot oxidation, and mold formation which can surely affect the final taste

How to Avoid This?

To clean the pot properly, disassemble it and wash each part with warm water. Use a soft brush or cloth to remove any coffee residue or oils that may have accumulated. Never use an abrasive brush for cleaning, which can remove the protective coating, and can lead to Moka pot oxidation.

Make sure to rinse the pot thoroughly and dry it before using it again. It’s best not to use any soap while you clean, as this can give your next batch of coffee an odd flavor.

7.     Using The Wrong Heat Source

Another important factor when using a Moka Pot is the heat source. Using the wrong heat source can result in uneven heating. This can affect the flavor of the coffee.

How to Avoid This?

To avoid this mistake, make sure to use a heat source that is appropriate for your Moka Pot. Most Moka Pots are designed to be used on a gas stove or induction stove.

Check your Moka Pot’s instructions to see what heat source is recommended. And make sure to use the appropriate one.

8.     Never Inspect the Parts of Moka Pot

Before brewing inspect Moka pot parts periodically whether any of the parts of the pot is damaged. Rubber gasket, filter screen, ground funnel, etc can be damaged due to overuse. If the funnel screen or filter mesh holes got bigger, the coffee won’t taste the same since water may pass through the funnel or filter too quickly.

Simply keep an eye on the Moka pot parts, and look for any visible damage. If anything is found faulty, replace it or buy a new Moka pot.

9.    Packing Too Much Coffee By Tamping

The amount of coffee used in a Moka Pot is also essential for making the perfect cup. A harsh flavor may arise from packing too much coffee. Whereas too little coffee might result in a poor brew.

How to Avoid This?

Fill the coffee ground container up to its neck, and gently level it with your hand. Never tamp so hard. Tamping will pack the coffee grounds in the ground container. As a result, water will face more resistance to pass through the ground.

Therefore, it will create overpressure in the water chamber. So, it can lead to sputtering, and Moka pot leaking.

10. Using A Wrong-Sized Pot

Using a pot of the incorrect size might also alter the flavor of the brew. If you have a large Moka pot but you want to brew less amount with it, the outcome won’t be good. In order to do that you need to use less water and less ground coffee than the particular Moka pot is designed for. You’ll end up with a weak cup of coffee.

How to Avoid This?

To avoid this mistake, make sure to use the appropriate pot size. Most Moka pots come in different sizes, so choose one that’s appropriate for your needs. If you are a single person, a 3-cup Moka pot will be ideal for you, and for couples 6-cup size is perfect.

11. Moka Pot Losing Pressure Over Time

When you use the same Moka pot for a long time, it can lose its pressure. The seal will start to wear down and lose its previous pressure with regular usage, and it’s normal.

How to Avoid This?

It is obvious that the Moka pot is losing its pressure if you notice your coffee is not giving the previous taste. Replace the gasket with this easy fix, and you can bring a lot of difference to your coffee. The gasket is the part that seals the pot and makes pressure intact.
