Black Seed Oil: Single Press or Double Press?
To return
When you buy black seed oil, one thing you might notice is that brands or companies will advertise the oil as being either one-time pressed (or single pressed) or two-time pressed (or double pressed). It’s not as self-explanatory as it sounds, and the difference is actually important.

The pressing process is where the oil is extracted from the black seeds. Different companies have different techniques and different ideas about the best way to extract the oil. But one thing that’s worth mentioning is that not all companies are dedicated to quality. Larger companies want to get as much oil as possible from the seeds because they have large markets to supply, and will usually prioritize volume over quality.

Let’s look at some specifics on how black seed oil is extracted and what you should look for when buying black seed oil

Before we get into the differences, you need to know how black seeds are pressed for oil. Most black seed oil producers will use either a commercial press or an industrial-quality press. Industrial presses are huge, heavy, and bulky, and have the capacity to press several times more seeds than a commercial-sized press.

Commercial presses are smaller, so black seed oil is crafted in smaller batches. The spiral, or tube, is also smaller, which allows it to only press a single layer of seeds at a time so that a second press isn’t necessary

How is Black Seed Oil Extracted?
Organic Seeds and oil?
Truth or Fiction?
A lot of companies, particularly in the Middle East, will use industrial machines because they can press more seeds in less time, thus producing more oil. When the seeds are pressed, they end up looking like shiny, flat pieces of plastic. Because so many seeds are pressed at once, many of them still contain oil after the pressing process is finished. They exit the press still wet, and then the companies put them back into the press for a second extraction.

In a way, this makes sense. These are big companies who are looking to supply big markets and need to squeeze as much out of their product as possible to make up volume.

The problem is that the quality diminishes during this second press. It’s not as clean, and the texture and flavor are altered.

In a single press process, the black seeds are spread out in the press in an even layer for maximum extraction. They’re minimally processed in this way to produce a better, cleaner oil

Single Press vs Double Press: What’s the Difference?

The general consensus among black seed oil consumers is that one-time press is best. The only way to know for sure what kind of oil you’re getting is to know the type of machine the company is using to press the black seeds in the first place.
