Coffee

Over the past couple of years, coffee has grown to be a more than a quick caffeine fix in the morning. I started seeing coffee as less of a consumption good and began enjoying it more consciously, informing myself about its cultivation, the origin of the beans, the roast and of course the brewing processes. I’ve tried many different variants and tools, from pour-overs using paper filters as well as re-usable ones, over Moka pots and the famous AeroPress up to the supreme discipline of pulling shots on a portafilter machine.

Solid Coffee, Hand-Pressed

One of my all-time favorite tools for brewing coffee has always been – and still is – the AeroPress by Alan Adler. While AeroPress, Inc. released a travel variant dubbed the AeroPress Go back in 2019, I still sport the O.G. 2014 model made out of dark brown polypropylene, although I might eventually upgrade to the 2023 AeroPress Clear made out of Tritan.

When I brew with the AeroPress, I prefer the inverted method.

Step 1: Grind coffee beans

We’ll be using 14 grams of coffee and 201 grams of boiling water. You’ll want to use a finer grind than for a regular filter coffee. Depending on the grinder you use the settings may vary and you might need to try-and-error a number of times. Generally speaking, if you have an espresso grind and a filter grind at hand, compare both and try to go in between them, in terms of coarseness.

Step 2: Boil water, prepare AeroPress

Heat 201g of water until it boils and meanwhile prepare the AeroPress. Place the plunger into the AeroPress until it reaches the number 4 and put it upside down (with the open end facing upwards) on a table. Then, add the 14g off ground coffee into it. Prepare the lid by placing a filter into it.

Step 3: Add hot water

First, add a little bit of hot water onto the filter – yes, that’s that 1g – so it sticks on the lid. Then fill up the AeroPress with the remaining 200g of water. Don’t rush it, but also don’t take too long to fill it up. Around 20 to 30 seconds should be fine. Afer that, wait one minute, give it a quick stir and add the lid. Wait another minute.

Step 4: Flip and press!

Add your cup upside down onto the AeroPress and with it in place, flip the whole contraption and press down the plunger. Don’t press too fast nor take too much time. Around 30 seconds from top to bottom should be good.

Your coffee is ready to be served!

Smooth Brew, Hand-Poured

Another very good and portable method for brewing coffee is the pourover. There are a wide variety of tools available, starting with the super portable Hario V60 Plastic Dripper, over the MOMA art piece which is the Chemex Coffeemaker, up to more fancy and fully automated coffee makers like the Ratio Eight.

When I brew pourover coffee, I prefer using the Able Kone instead of paper filters. The Kone is available for the Chemex as well as the V60 02 coffee drippers.

Step 1: Grind coffee beans, boil water

We’ll need 30g of coarse, sea salt-like ground coffee and 600g of water. Bring the water to a boil while grinding the coffee and adding it into the filter. In case you’ll be using a paper filter you might want to pre-wet it, unless your paper filter brand says otherwise.

Step 2: First pour

Start a timer and begin pouring water slowly, starting in the center, moving in a steady spiral towards the edge and back again. You should be pouring around 60g of water within 15 seconds. Wait 30 seconds after the first pour to allow the coffee to bloom.

Step 3: Second pour

Just like in with the first pour, start in the center and pour water in a steady spiral toward the outer edge and back again. This time we’ll be pouring around 90g of water within roughly 15 seconds. Wait around 50 seconds afterwards.

Step 4: Third pour

After the water from the second pour dropped to the bottom of the filter, pour 100g of water using the same pattern as before, again within roughly 15 seconds. Afterwards wait for another 30 seconds.

Step 5: Fourth pour

For the fourth and final pour add 100g of water within 20 second, again using the same pattern as before. Wait until the coffee stopped dripping.

Your coffee is ready to be served!

While I enjoyed these different hand-brewing variants over extensive periods of time and dialled different knobs – like the bean origin and the roast – to vary the cups of coffee I was getting out of these preparation methods, at the end of the day I kept coming back for a good espresso from my Rancilio Silvia.

I loved the Silvia for being a very compact yet powerful espresso machine. Even though it had its shortcomings, like the lack of a pressure gauge or its unstable brewing temperature, I managed to get some very decent cups of coffee out of it. The Macap M2D I had standing next to it did a good job at grinding the freshly roasted espresso beans consistently enough so that the Silvia would not only work with the coffee grounds but also produce some very thick and stable crema along the way.

Unfortunately a full-size espresso machine is not exactly cabin luggage, so I had to give it away one day. Forced to find an alternative, I tested a few options and eventually ended up with what’s now part of my essential travel equipments list: The Aram Espresso Maker.

Beautiful Espresso, No Electricity Required

The Aram Espresso Maker (or Coffee Maker, how it was still called when I got mine) is a minimalistic and very high quality tool for extracting genuine espresso using a fully manual process. To do so, ground coffee and some boiling water is required.

Info: While I still own my Aram Espresso Maker and would still recommend it to others from a purely qualitative aspect, I have learned that when something should break - like it did with the gasket on mine - it will a lot of trouble to get replacement parts to fix it, especially during these times.

My Aram has been out of order since the beginning of 2021. There aren’t many parts that can break on this device, but if even a single of of them does you’re basically screwed and have to wait for Aram to have the part in stock as well as be able to receive it.

I’m not even mad about Aram not being able to offer a quicker way to get replacements, but what I’m mad about is the fact that especially at the price of ~$500 one could expect that they would at least add replacement parts for the parts that will experience the most wearing, like gaskets. These parts cost basically nothing in bulk and it would save customers in case they fail.

Update: It turns out that other gaskets have also deteriorated and broke. I’m yet on the hunt for replacement parts. Communication with Aram has become tedious, simply because it takes ages for them to get back and even when they do, misunderstandings seem to happen. I’ve tried finding the broken parts at hardware stores nearby, but haven’t had any success so far.

Update: It’s January 2022 and it has been almost a year since I had to put the Aram out of service due to broken gaskets. Communication with Aram is bad, like really bad. At some point they simply stopped responding. I was trying to order (and pay for) the replacement gaskets from them, but it seems like helping out their customers is not their top priority at all. Eventually I found an online hardware store that’s located somewhere in Europe, that had gaskets that are similar to the ones used by Aram. I gave it a shot, ordered them and was able to fix my Aram just recently.

The gaskets don’t fit 100% though. While the Aram works and the pressure seems fine, I’m still very disappointed by Aram support. It’s possible to fix the Espresso Maker using third party components, although it’s less than ideal, especially at the price at which Aram positioned their device. It feels like fixing a Ferrari by using scrapped components from an old Fiat - it’s certainly possible but definitely not the experience you’d expect.

Step 1: Grind coffee beans

The first thing you’ll need to get a good cup of espresso from the Aram is obviously a handful of good quality roasted beans of your liking and a good grinder. To make it clear upfront: The Aram won’t work with most pre-ground coffee (e.g. from supermarkets or maybe even from your local coffee shop) as it’s quite pretentious in terms of grind coarseness. You will definitely need a decent grinder that will allow you to fine-tune the grind level, otherwise you won’t be getting anything close to a good espresso out of it.

I use a Comandante C40 hand grinder. I tried cheaper hand grinders (like the Hario Mini Slim) with the Aram but couldn’t get a satisfiable result with those grinds. Even with the Comandante it took me a few cups until I got the flavour on point.

As for the amount, I would suggest going with approximately 19g. I used to use a scale for getting the right amount, but eventually I got the feeling for it and could spare an expensive scale. I found that as soon as I dialled the grinder to a good setting, small variations in the amount are totally okay and in fact produce very interesting taste profiles.

Step 2: Boil water and preheat

Preheating is key to success with the Aram. It’s a chunk of 304 stainless steel that absorbs an incredible amount of heat, hence it requires a few rounds of how water running through it before the actual brew can happen. I usually boil the water, pour it into the Aram (with its valve fully closed) and let it sit for two to three minutes, while I keep the rest of the hot water at a near-boiling temperature. Then I turn the crank to open the valve and let the water run back into the pot/boiler/kettle, where I make it boil just to pour it back into the Aram and let it stay for a bit again.

I repeat this two to three times, until I can feel that the Aram’s exterior got close to being uncomfortably warm. You could stick a thin thermometer through the holes on the top to measure how the water temperature changes, but, duh, nerd.

Hint: Don’t use tap water unless you know the mineral content of it. As I’ve detailed previously (search for TDS), not all water is the same, hence the resulting cup of coffee will taste differently depending on the water that you use. I usually prefer bottled water for which I can look up its mineral content, to make sure it is in the acceptable range for espresso.

Step 3: Pull the shot

As soon as I drained the chamber, I use a cloth to dry the bottom part and attach the filter containing the tampered coffee and connect the glass underneath. Then I pour the boiling water into it and turn the crank as quickly as possible until the screw thread reached its upper end. After that I quickly turn the crank the other way around until I can feel the pressure building up, which is when I start slowing down. At that point the espresso starts flowing and becomes brighter and brighter with every turn.

I usually stop the extraction as soon as I got the desired amount of coffee in the cup. This is done by spinning the crank back up until you hear a slurping sound, which is when the negative pressure kicks in, stopping the coffee from flowing. The glass can then be removed safely and the rest of the water inside the chamber can be drained afterwards.

Coffee beans

In addition to the tools that I use and the actual espresso brewing process, I’m also beginning to maintain this list of some of the coffee beans that I’ve had so far. This list will grow over time and I will try to look up older roasts and add them as well.

These are all espresso roasts. The rating is my very personal rating for the individual roasts. Keep in mind that coffee is seasonal and hence not constant in availability nor flavour.
