This guide introduces simple preheating methods that can help achieve a more stable temperature when using the Leverpresso Orbit. These methods are based on my personal workflow, and if you have other useful techniques, feel free to share them.
Temperature plays an important role in espresso extraction and flavor development.
Unlike electric espresso machines, the Leverpresso Orbit was designed as a portable espresso maker that extracts coffee using hot water without a built-in heater. Because of this design, the temperature of the device can influence the final espresso beverage temperature.
Preheating is not required, but it can be helpful for users who are sensitive to temperature or prefer a hotter espresso.
The body of the Leverpresso Orbit is made of stainless steel. While stainless steel absorbs and retains heat well, it can initially draw heat away from the brewing water. For users who want to reduce this temperature loss, preheating the device can help stabilize the brewing temperature.
As shown in the thermal image, when hot water enters the Leverpresso Orbit, the temperature gradually rises around the center of the cylinder, demonstrating how the body warms up. By increasing the temperature of the body beforehand, heat loss during extraction can be reduced.
Although individual preferences may vary, preheating the Leverpresso Orbit can help achieve an espresso beverage temperature in the range of 70–80 °C (158–176 °F).
To help maintain a more stable temperature during brewing, the Leverpresso Orbit was designed with a relatively large 120 ml cylinder. Filling the cylinder with a sufficient amount of hot water can warm the body effectively and help maintain a more stable espresso beverage temperature during extraction.
Basic Preheating Method
In the video, a thermometer is shown only to demonstrate the temperature change during preheating. The footage is played at 2× speed.
1. Fill the chamber completely with boiling water.
2.Preheat your espresso cup by filling it with hot water as well.
3.Allow the metal body to absorb heat for a short moment.
4.Discard the water and proceed with normal espresso extraction.
Using this method, the espresso beverage temperature will typically reach around 70 °C (158 °F).
Higher Temperature Preheating Method
If you prefer a hotter espresso, you can use a more intensive preheating method. With sufficient preheating, it is possible to achieve an espresso beverage temperature above approximately 75 °C (167 °F).
Follow the steps below:
1. Prepare a steam pitcher or cup slightly larger than the Leverpresso Orbit.
2.Place the device inside with the lever in the raised position.
3.Pour boiling water into the Leverpresso Orbit water inlet, allowing the body to become surrounded by hot water.
4.If necessary, add more hot water so that the entire body is heated evenly.
5.Once the body is sufficiently warmed, raise and lower the lever to remove the water inside the cylinder.
6.Attach the prepared portafilter and proceed with extraction.
Additional Preheating Methods Used by Some Users
Some users also apply the following methods:
- Placing the Leverpresso body inside an electric kettle while heating water
- Resting the device above a boiling kettle to warm the body with steam
Leverpresso is built with materials capable of handling high temperatures.
The Leverpresso Orbit is built with materials capable of handling high temperatures.
However, please note that the silicone seals used in the product have a heat resistance of approximately 150 °C (302 °F). As long as the device is used within this range, it can be safely preheated.
