The Delter Coffee Press and the Aeropress are two popular coffee makers that are known for their portability and unique chamber and seal mechanism. Both are extremely easy to use, all you need to do is add water in order to have a brew that is ready in less than 5 minutes.
Delter was invented in 2018 while the Aeropress goes all the way back to 2005, and has since become a staple in brewing competitions.
The Delter and Aeropress look extremely similar, so one could be excused for thinking they work in exactly the same way.
There are, however, some key differences to be aware of that can influence the coffee-making process as well as the end result.
Even though both are very easy to use, one offers a little more control of the variables, which experienced and aspiring brewers will both appreciate.
To help you make the right decision based on your brewing style and personal preferences, we’ve analysed the key similarities and differences between the Delter and the Aeropress and explained them below.
One of the key similarities between the Aeropress and the Delter Press is their size. Both are very portable and ideal for camping trips, travelling, or if you do not have a ton of space at home for larger coffee equipment.

They can fit almost anywhere and can be assembled and cleaned in no time. The mechanism in both is centered around the chamber and the plunger, which creates a seal and applies pressure to the coffee grounds.
Both methods use a round paper filter that helps get rid of sediments and excess oil in order to produce a clean cup of coffee.
They are also very user-friendly coffee makers and most users get the hang of operating these devices fairly quickly.
Another thing the Delter and the Aerpress have in common is the need for a fine coffee grind.
This is what helps mimic an espresso and is one of the key factors involved in making coffee that doesn’t take a lot of time.

Immersion vs Injection Brewing
The Aeropress uses immersion brewing, similar to a french press. This basically means that your coffee grounds are fully in contact with the water for a period of time.
Once the filter is secured in the chamber, all you need to do is add coffee (fine grind size) followed by hot water before using the stirrer to agitate (a key step in the Aeropress process).
You can then start applying pressure to the plunger. This whole process doesn’t take more than 5 minutes.
The AeroPress comes with a stirrer (so you can incorporate the coffee grounds with the water as mentioned above) and a measuring scoop.
The Delter Press, on the other hand, uses injection brewing.
This method prevents uncontrolled agitation and has a more volumetric approach. The process works thanks to the jet seal mechanism which separates water from the coffee until you start brewing.
Injection brewing allows you to control the volume, time, and amount of pressure you apply, almost like an espresso machine. This method also allows you to pre-wet your coffee grounds (i.e. bloom) with a gentle pour of hot water before adding the rest.
The Delter Coffee Press doesn’t include a measuring scoop.
Another key difference is the brewing capacity. The Aeropress has a capacity of a single serving, around 220ml, while the Delter has twice that capacity, around 400ml.
If you are brewing for more than one person, you will have to clean your Aeropress and begin the process again.
Thanks to its much larger capacity, the Delter Press can brew up to 25 grams of coffee in one single extraction.
Last but not least, agitation. When using the Aeropress, you must agitate the coffee with the water in order to make sure that all coffee grounds are completely wet. However, too much agitation can create a bitter taste.
The Delter Coffee Press prevents unwanted agitation, thanks to its injection brewing mechanism, as the coffee is separated from the water within the chamber until you are ready to start brewing.

Making Your Selection
The Aeropress Coffee Maker is very affordable and is generally considered to be very hard to damage or break. It is extremely easy to clean and brews a great-tasting single cup of coffee. These factors alone make it a great choice for most people.
The Delter Coffee Press can brew two coffee servings and is able to deliver a bright and clean cup thanks to the jet seal and injection method.
Both products have a very well thought design and offer great value for their given price (which is just a couple of dollars difference).
In the end, the selection decision comes down to the following:
If you are someone that drinks one cup of coffee at a time, is fond of immersion brewing (e.g. plunger coffee), then the Aeropress Coffee Maker is for you. The taste can be quite similar to that from a plunger however with the Aeropress you can have coffee ready in as fast as one minute if you desire it.
One downside of the Aeropress is that it offers a more traditional brewing process that does not leave a lot of room for experimenting. There are, however, still some variations available, notably the inverted method.
If you want to make more than one coffee at a time, and enjoy methods that deliver a cleaner and brighter cup, like a V60, then the Delter Coffee Press is probably the best bet for you.
The Delter offers the possibility of controlling both the pressure and time of your brewing, which is an advantage if you are more experienced in that area and want to experiment with those features.
What is Aeropress good for?
The Aeropress is good for loosely replicating an espresso. Thanks to the plunger, the amount of pressure inside the Aeropress mimics the brewing process of an espresso machine. Due to its design, an extraction can take from 1 to 3 minutes, which is a plus for people that do not have a lot of time in the morning to make their coffee. It is also easy to clean and portable. Thanks to the paper filter, your cup of coffee will have a clear, oil-free flavour. This method is also good for people that like versatility, as you can brew in both the traditional method or the inverted method.
Is Aeropress better than V60?
We wouldn’t say that the Aeropress is better, but it is definitely different. The V60, thanks to the nature of the brewing method, can deliver a cleaner cup as it doesn’t use any pressure. It all comes down to your preference when drinking coffee. The V60 can also brew a larger quantity and it also needs a coarser grind than the Aeropress. However, if you’d like to replicate something along the lines of espresso and but without the machine, go with the Aeropress.
