If you enjoy Café Crème, the Trinity Zero offers an interesting mobile alternative. Although the coffee press from Australia doesn't produce crema, the coffee result is still impressive. The Trinity Zero Coffee Press weighs 115 grams. And in terms of size, the Trinity Zero is also truly handy.
The brewing chamber has a height of 4.5 cm. The lid is placed on top, with an integrated rubber lip and finger pump. The brewer itself has a diameter of 9 cm. The 2 cm high coffee chamber can be stored in the brewing chamber for transport. A fine-holed sieve made of stainless steel (AISI 304) is inserted into the brewing chamber.
Brewing instructions for the Trinity Zero
We use 18 grams of medium-fine ground coffee. A grind size in the finer filter coffee range is a good guideline. During brewing, you can then determine whether the grind size is correct or needs to be adjusted for the next brew.
The water is boiled and used at boiling temperature. 100 ml are needed. No scale is necessary for adding the water, as the water chamber provides a practical guide. Once the water has been added, close the lid to prevent temperature loss.
From the moment of pouring, we wait around 30 - 40 seconds before starting to press through. We press the rubber pump area into the brewer with our thumb or index finger. This requires no effort.
If the grind size is chosen correctly, a few continuous streams of coffee water flow into the collection vessel. If the coffee only drips into the container, the grind size is too fine. If the coffee splashes into the vessel in many streams, the grind size is too coarse.
I recommend pressing the pump with your thumb and holding it for approx. 3 - 5 seconds. Then release, allowing air to flow into the Trinity Zero, and then press again.
After 5 to 7 presses, all the coffee is in the cup in approx. 1.20 to 1.30 minutes.
How does Trinity Zero coffee taste?
The coffee sensorily resembles a strong, long coffee. It tastes like what I imagine a good Café Crème to be, but without crema. The coffee has a texture and, depending on the coffee, feels creamy in the mouth, significantly thicker than filter coffee.
Compared to filter coffee, the coffee appears concentrated and unusually strong. Nevertheless, the sweetness of the drink creates balance. Because the coffee is only filtered through a metal sieve, fine particles contribute to the mouthfeel of the drink. This distinguishes the coffee from a concentrated Aeropress extraction, which is paper-filtered.
Improving Trinity Zero coffee
Depending on taste, the extraction of the Trinity Zero can be adjusted or improved. The brewing ratio of 18 to 100 ml, i.e. 1:5.55, results in a concentrated cup of coffee with a volume of approx. 70 ml. The concentration of dissolved coffee particles is between 3.2 and 3.5 TDS% (total dissolved solids).
If you prefer less concentrated coffees, you can extend the drink by adding 60 - 80 degree hot water. To, for example, turn a 70ml brew with 3.3% TDS into a strong filter coffee with 1.5% TDS, approx. 84 ml of water are added.
Of course, milk or milk foam can also be added. I have written an article here on calculating the bypass amount.
Which coffee for the Trinity Zero?
Personally, I like coffees that are roasted for filter coffee. Some filter coffees with pronounced acidity are a bit sharp in the concentrated version of the drink. This can be corrected by adding a bypass.
If you like to drink coffee with milk, a stronger roast is better advised. This can come through the milk flavor better and leads to a more interesting and complex drink.
