If you enjoy café crème, the Trinity Zero offers an interesting mobile alternative. Although the French press from Australia doesn't produce crema, the coffee result is impressive. The Trinity Zero Coffee Press weighs just 115 grams. And in terms of size, the Trinity Zero is truly compact.
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 inside the brewing chamber for transport. A fine-mesh filter 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 reference point. During brewing, you can 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 is required. You don't need a scale to measure the water, as the water chamber provides a practical guide. Once the water has been added, close the lid to prevent heat loss.
From the moment the water is poured, we wait about 30 - 40 seconds before starting to press through. We push the rubber pump area into the brewer with your thumb or index finger. This requires no effort.
If the grind size is correct, several continuous streams of coffee water flow into the collection vessel. If the coffee only drips into the container, the grind is too fine. If the coffee sprays in many streams into the vessel, the grind is too coarse.
I recommend pushing the pump down with your thumb and holding it for approximately 3 - 5 seconds. Then release it, allowing air to flow into the Trinity Zero, and then press again.
After 5 to 7 strokes, all the coffee is in your cup in approximately 1.20 to 1.30 minutes.
How Does the Coffee from the Trinity Zero Taste?
The coffee reminds you sensorially of a strong long coffee. It tastes like I imagine a good café crème would taste, but without the crema. The coffee has a texture and feels creamy on the palate depending on the coffee, significantly thicker than filter coffee.
Compared to filter coffee, the coffee tastes 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 mouthfeel of the drink. This distinguishes it from a concentrated Aeropress extraction, which is filtered through paper.
Improving Trinity Zero Coffee
Depending on your 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).
If you prefer less concentrated coffees, you can extend the drink by adding 60 - 80 degree hot water. For example, to turn a 70ml extraction with 3.3 %TDS into a strong filter coffee with 1.5 %TDS, add approximately 84 ml of water.
You can also add milk or milk foam. To calculate the bypass amount, I've written an article about it here.
Which Coffee for the Trinity Zero?
Personally, I enjoy coffees roasted for filter coffee. Some filter coffees with pronounced acidity can taste a bit sharp in the concentrated version of the drink. This can be corrected by adding a bypass.
If you prefer to drink your coffee mixed with milk, a stronger roast is the better choice. It can shine better through the milk flavor and results in a more interesting and complex drink.
