If you enjoy café crème, the Trinity Zero offers an interesting mobile alternative. While the coffee press from Australia doesn't produce crema, the coffee result is impressive. The Trinity Zero Coffee Press weighs 115 grams. And as far as size goes, the Trinity Zero is 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. Inserted into the brewing chamber is a fine-mesh filter made of stainless steel (AISI 304).
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 reference point. During brewing, you can then determine whether the grind size is right or needs to be adjusted for the next brew.
The water is boiled and used at boiling temperature. 100 ml are required. A scale is not necessary for adding the water, as the water chamber provides a practical reference guide. Once the water has been added, close the lid so that no temperature is lost.
From the moment the water is poured, wait approximately 30 - 40 seconds before you begin pressing through. We press the rubber pump area into the brewer with the thumb or index finger. This requires no effort.
If the grind size is chosen correctly, several 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 sprays into the vessel in many streams, the grind size is too coarse.
I recommend pressing down the pump with your thumb and holding it for approximately 3 - 5 seconds. Then release it so that air can flow into the Trinity Zero and then press again.
After 5 to 7 pushes, all the coffee is in your cup in approximately 1.20 to 1.30 minutes.
What does the coffee from the Trinity Zero taste like?
The coffee is sensorially reminiscent of a strong long coffee. It tastes the way I imagine a good café crème to taste, albeit without crema. The coffee has a texture and feels creamy on the palate depending on the coffee, noticeably thicker than filter coffee.
Compared to filter coffee, the coffee seems concentrated and unusually strong. The sweetness of the drink still provides balance. Because the coffee is only filtered through a metal mesh, fine particles contribute to the tactile sensation of the drink. This distinguishes the coffee from a concentrated AeroPress extraction, which is filtered through paper.
Improving Trinity Zero Coffee
Depending on preference, the extraction of the Trinity Zero can be adjusted or improved. The brewing ratio of 18 to 100 ml, or 1:5.55, results in a concentrated cup of coffee with a volume of approximately 70 ml. The concentration of dissolved coffee solids is between 3.2 and 3.5 TDS% (total dissolved solids).
Those who prefer less concentrated coffees can dilute the drink by adding water at 60 - 80 degrees. For example, to turn a 70ml shot with 3.3% TDS into a strong filter coffee with 1.5% TDS, approximately 84 ml of water is added.
Milk or milk foam can of course also be added. For calculating the bypass amount, I've written an article here.
Which coffee for the Trinity Zero?
Personally, I enjoy coffees that are roasted for filter coffee. Some filter coffees with pronounced acidity can taste a bit sharp in the concentrated version of this drink. This can be corrected by adding a bypass.
Those who prefer to drink their coffee mixed with milk are better served with a stronger roast. This can work better through the milk flavor and results in a more interesting and complex drink.
