Why We Extract One Liter Per Hour

Speed Creates Friction. Friction Creates Heat.

When you force thousands of seeds through a high-speed industrial expeller press, the mechanical friction creates intense localized heat. Even if the manufacturer does not turn on an external heating element, the machine itself cooks the oil. This friction heat degrades the volatile therapeutic compounds, specifically the Thymoquinone.

To hide this reality, mass-market brands rely on a massive industry loophole: there is absolutely no legal temperature standard for what constitutes "cold-pressed" black seed oil.

In Spain, 27°C is the strict, legally defined ceiling for Extra Virgin Olive Oil. But the rest of the Cold Pressed Oil industry has zero regulation, except for few minor suggestions that are not enforceable. A brand can run a high-speed press, let friction heat spike past 60°C, and still legally print "Cold Pressed" simply because they didn't turn on a heater. They hide the machine's internal temperature because the law lets them.

1 Liter Per Hour: Why and How?

By capping production at this pace, we minimize the mechanical friction that spikes temperatures and cooks delicate compounds like Thymoquinone.

How we pull it off: Extracting oil at a crawl sounds simple until you actually try it.

Think of driving up a steep mountain road. A tiny, weak engine has to rev at high RPMs just to make the climb, generating intense heat under the hood. A big V8 engine pulls that exact same load effortlessly at a low purr.

Most oil presses are tiny engines. If you slow them down, they choke on tough seeds, forcing operators to run them fast and generate friction heat.

Our German Oelwerk press is built with serious low-end muscle. Its heavy-torque motor crushes seeds effortlessly at a snail's pace, giving us better temperature control and minimizing friction heat

Temperature Monitoring

We have an external temperature sensor with the probe right next to the exit point of the oil. So far, we have been witnessing temperatures range strictly between 35°C and 39°C throughout our runs.

See It For Yourself

We record every single extraction session and upload the full footage to YouTube. In the future, we will also be live-streaming our pressing runs so you can watch the process in real time.
