Aluminum Moka Pot vs. Stainless Steel – Which is Better From a Taste and Safety Perspective

What is a Moka Pot anyways?

aluminum vs stainless steel moka potsBasically, a Moka Pot is an appliance in which it uses pressure (similar to how pressure cookers work) to brew coffee. The pot itself has three distinct chambers. The first chamber is located at the bottom and is filled with water. The pressure built up in this chamber allows the water to rise and flow through the second chamber.

The second chamber is funnel shaped wherein the ground coffee is placed here. The reason it is funnel shaped is because the water, when boiling, rises through the funnel to reach and brew the ground coffee in the middle chamber. Of course, this middle chamber has small holes to prevent the ground coffee from falling into the first chamber as well as to allow the water to go through the second chamber.

The third chamber is where the brewed coffee is collected. Now, the shape of the third and top chamber is a sort of reverse funnel wherein there is a tall funnel in the centre from which the brewed coffee flows.

As a result, the brewed coffee is much hotter than when brewed in a standard pot, due to the superheated water resulting from the use of pressure.

Safety Measures

All Moka Pots are equipped with gaskets that ensure that there is a safe build-up of pressure in the lower chamber. Since the Moka Pot separates into three, the gaskets are there to hold the chambers together while also keeping pressure from escaping through the separations.

Moka Pots are also equipped with safety valves. These valves are another avenue from which steam escapes. Of course, Steam can only escape through these safety valves in the case of intense build-up or in other words, too much steam is accumulated in the lower chamber. On the other hand, a clean filter in the second chamber will prevent unnecessary steam build-up since this is the main pathway where steam will pass through. This will also ensure that the coffee is finely brewed.

In addition, some recipes state how much water to use per amount of coffee bean. This ratio is very important is this plays a huge role in the outcome of the flavour of coffee. Knowing to use how much water also serves another purpose. This keeps the pot from generating too much pressure which worsens the quality of the coffee and poses possible damage to the pot.

Coffee Characteristics of the Moka Brew

You may now be wondering how different coffee tastes when brewed using a standard pot or coffee maker as compared to using the Moka pot. For starters, the taste and flavour of coffee generated by a Moka pot greatly rely on several factors such as the type of coffee bean, roast level, how fine the grind is and as mentioned, the amount of temperature in the pot.

The design of the Moka pot, in which it uses superheated water and pressure to brew coffee, results in a stronger flavour as compared to the standard pot and drip brewing. This is because there is more caffeine present in the brew of Moka pots. Moka pots also generate more crema or foam as compared to other brewing mechanisms.

Due to the extraction rate of the Moka pot, meaning the amount of coffee brewed, most people commonly mistake the Moka pot as a variation of an Espresso machine. This is not the case since Moka pots generate a PSI of 29 as compared to 130 of Espresso machines. Thus, Moka brews are not classified as Espresso and should be considered as distinct type of coffee brew in itself.

Aluminum vs. Stainless Steel

Moka pots were traditionally made of aluminium due to its malleability, making the crafting process of complex shapes and features much easier compared to when using thicker metals such as steel. There are still Moka pots available out there on the market but manufacturers such as Alessi, Serafino Zani, Vev Vigano and Bellman have now designed Moka pots made of stainless steel apart from their aluminium offerings.

The pots practically offer the same features and functionality but do both materials actually contribute to users in terms of taste and safety?

This question can be answered through the comparison of four benchmarks discussed below.

Winner: Stainless steel

Winner: Aluminum

Winner: Stainless steel

Winner: Stainless steel

Winner: Aluminum

Conclusion

Based on the breakdown above, one should definitely opt for a stainless steel pot. The health scares are primarily rooted in corrosion in which stainless steel is more resistant. Also, due to stainless steel’s durability, it is more likely to withstand the intense pressure generated by the lower chamber.

Taste-wise, both pots go either way. As mentioned above, the flavour generated by a Moka pot really depends on the aforementioned factors and thus, the characteristics of aluminium and stainless steel pots have no room in the discussion.

If one is looking for a more traditional tasting Moka brew, one should then opt for aluminium pots since traditional Moka pots were made of aluminium. Of course, one should always keep in mind that hazards that go along with it.
