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 in terms of size, the Trinity Zero is truly handy.
The brewing chamber has a height of 4.5 cm. The lid is placed on top, featuring 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 determine whether the grind size is right or needs to be adjusted for the next brewing.
The water is brought to a boil and used hot. 100 ml is required. A scale is not necessary for adding water, as the water chamber provides a practical reference guide. Once the water has been added, close the lid to avoid losing temperature.
From the moment of pouring, we wait approximately 30 - 40 seconds before we start pressing. We press the rubber pump area into the brewer with our thumb or index finger. This is effortless.
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 in many streams into the vessel, the grind size is too coarse.
I recommend pressing the pump down 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 strokes, all the coffee is in the cup in approximately 1.20 to 1.30 minutes.
What Does the Trinity Zero Coffee Taste Like?
The coffee is sensorially reminiscent of 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 feels creamy on the palate depending on the coffee, distinctly thicker than a filter coffee.
Compared to filter coffee, the coffee tastes concentrated and unusually strong. The sweetness of the drink nonetheless creates balance. Because the coffee is only filtered through a metal sieve, fine particles contribute to the texture 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 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. For example, to make a strong filter coffee with 1.5 %TDS from a 70ml shot with 3.3 %TDS, approximately 84 ml of water is added.
Of course, milk or milk foam can also be added. To calculate the bypass amount, I've written an article here.
Which Coffee for the Trinity Zero?
Personally, I like coffees that are roasted for filter coffee. Some filter coffees with pronounced acidity are somewhat sharp in the concentrated version of the drink. This can be corrected by adding a bypass.
If you like to drink your coffee mixed with milk, you're better off with a stronger roast. This can shine through the milk flavor better and results in a more interesting and complex drink.
